Abstract: Embodiments disclosed herein are directed to an identification insert and assembly alignment feature for a subcutaneous access port. The port can include an identification insert assembled with the device and configured to be visible under medical imaging when placed subcutaneously. The insert can indicate a property of the port and a location or orientation of the port to facilitate access thereto. An alignment feature can be configured to align the insert with the port in a first orientation during manufacture. The alignment feature can also be configured to misalign the insert with the port in a second orientation, different from the first orientation. This can prevent the port from being assembled if the insert is coupled with the port incorrectly. A port having an insert assembled incorrectly can lead to unnecessary disruptions and complications to the patient to correct the problem.

Abstract: Methods, devices, or systems that may allow for remote monitoring of a capture area or the automatic inspection of a capture area, such as an adhesive board, among other things. In one aspect, the disclosed subject matter includes receiving an image of a capture area, generating current detection boxes associated with objects (e.g., pests) by performing object detection on the image, determining output boxes by comparing the current detection boxes with historical detection boxes, generating the output boxes, and transmitting an object count based on the output boxes.

Abstract: An image may be received from a sensor associated with a capture area. Background elements associated with the capture area may be removed and a cleaned image generated. Objects may then be detected in this cleaned image. A spatial partition model may be generated to understand z-index and partially obscured areas while preserving relative object sizes. This model may be used to determine and remove foreground elements that may obstruct objects of interest. Object detection may be performed again on the further cleaned image. Detected objects may be filtered based on predefined criteria for different object classes.

Abstract: An adaptive object recognition system utilizes relevance-based weighting and scoring that may assist with accuracy and stability. The system receives multiple recognition results for objects across video frames. Weights are assigned to results based on their stability over frames and the relevance scoring of neighboring areas. This allows more confidence to be placed in consistent detections and clearer image regions. The system decouples high and low accuracy areas to apply appropriate thresholding. Temporal analysis is used to favor frequently detected objects. Weighted results are combined to generate final recognitions that are more robust to non-uniform image quality and noise.

Abstract: Embodiments disclosed herein are directed to a cathlock system integrally formed with a port or similar access device. The cathlock mechanism can include a shroud defining a recess, a stem disposed therein, and a collet lock transitionable between an unlocked and a locked configuration. The system can further include a tool configured to engage an outer surface of the cathlock and plastically deform the collet lock into the recess to the locked configuration. The collet lock can compress the catheter onto the stem to form a fluid-tight seal therebetween. The collet lock can be configured to engage the cathlock mechanism in the open configuration to facilitate coupling the catheter with the cathlock within the confined environment of a subcutaneous placement. Embodiments can include an extension leg disposed between the port and the cathlock mechanism.

Abstract: The techniques disclosed herein enable systems to safely deploy a plurality of upgrade variants to different resource units that provide a service by utilizing small-scale deployment and validation. To deploy upgrade variants, a system receives a selection of upgrade variants from a feature group and automatically selects an appropriate set of resource units at which to deploy the upgrade variants. The system is further configured to collect and analyze telemetry data from the set of resource units to determine if any problems have occurred as a result of the deployed upgrade variants. By analyzing the telemetry data, the system can also identify one or more upgrade variants that are causing the problems. In response, the system can remove the identified variants and proceed with deployment of the remaining upgrade variants.

Abstract: Embodiments disclosed herein are directed to a dual, in-line port having a body defining a first reservoir and a second reservoir arranged along a central port axis. Dual, in-line ports can be advantageous since the port can be placed through an incision site, along the central port axis, requiring a smaller incision site than side-by-side dual ports. Further, the port can include a stem extending from a side surface of the body, between the first and second reservoirs, the stem can be angled such that an axis of the catheter can extend parallel to the central port axis. The angled, side stem can mitigate disparities in fluid paths and fluid resistance between the first and second reservoirs and the respective catheter lumen. Embodiments can include a pivotable stem configured to allow an axis of the stem to be repositioned relative to the central port axis.

Abstract: Embodiments disclosed herein are directed to an anti-ingrowth cathlock including a compliant gasket. The cathlock can engage an outer surface of a catheter and secure the catheter to a stem of a port, or similar vascular access device, The gasket can be compressed between the cathlock and one of the catheter, stem, or port body to form a continuous outer profile therebetween and mitigate tissue ingrowth. Due to the tolerances during manufacture of the catheter, cathlock and port, gaps can occur between these portions when assembled, allowing for tissue ingrowth and complicating explantation of the port/catheter/cathlock assembly. The compliant gasket can be disposed on one of the port or the catheter and can fill these gaps, mitigating tissue ingrowth.

Abstract: Embodiments disclosed herein are directed to a multi-function adapter system for placing a distal tip of a catheter at a target location. The system is configured to maintain one or more electrical communication pathways with the catheter distal tip during a placement procedure. Two or more electrical pathways can be cross-referenced to determine accuracy. The electrical pathways can include a clip and first tether that provides a versatile electrical pathway in that the clip can be selectively coupled with either a saline column, stylet, guidewire, or needle. A flushing adapter can include a second tether formed integrally therewith and provide a second electrical pathway with a saline column. The stylet or guidewire can be fixedly coupled with the flushing adapter and can provide a second electrical pathway with the second tether. These electrical pathways can provide a fail-safe system to ensure electrical communication with the distal tip of the catheter.

Abstract: Embodiments disclosed herein are directed to a clamshell carhlock device and methods thereof. The cathlock includes a first portion hingedly coupled to a second portion and rotatable through a plane extending perpendicular to a central longitudinal axis. A user can apply opposing, radially inward, “pinching” force to transition the cathlock to the closed position, mitigating applying any pressure directly to the patient. The cathlock further includes a compliant sleeve coupled to an inner surface thereof and configured to slidably engage the cathlock with the catheter in both the open and closed positions. The sleeve can engage the catheter in an interference fit to allow a user to position the cathlock along the catheter and for the cathlock to remain in place until repositioned.

Abstract: Embodiments disclosed herein are directed to a dual, in-line port having a direct fluid path between the proximal reservoir and the stem. The port includes a conduit extending through the distal reservoir and defining a lumen in fluid communication with the proximal reservoir and the stem. The axis of the conduit lumen is aligned with stem lumen to minimize any tortuous fluid pathway and reduce fluid flow resistance. The port can further include a needle guard extending over the distal reservoir and configured to prevent an access needle from impinging on the conduit when accessing the distal reservoir. Embodiments can further include a removable reservoir insert that defines the distal reservoir.

Abstract: Embodiments disclosed herein are directed to an integrated cathlock mechanism configured to engage an outer surface of a catheter to secure the catheter to a stem of a port, or similar medical device. The engagement structure can include a plurality of fins or an O-ring. The cathlock mechanism can include an engagement structure disposed annularly about the stem and configured to transition between an unlocked and locked configuration. The cathlock mechanism can be biased towards a locked configuration. A tab can selectively engage the cathlock mechanism and can maintain the cathlock mechanism in an unlocked configuration. Urging the catheter into the cathlock mechanism and onto the stem can engage the stem in an interference fit. A user can then remove the tab to transition the cathlock mechanism to the lock configuration.

Abstract: Embodiments are directed to a port system including a port having a reservoir and a port lumen communicating therewith, and a connector having a stem defining a stem lumen and extending along a longitudinal axis. The stem can engage a catheter, providing fluid communication therewith. The connector can then be slidably engaged with the port along an axis extending perpendicular to the longitudinal axis, e.g. a transverse axis, until the stem lumen aligns with a port lumen. The connector can further include a locking pin slidable along a longitudinal axis and configured to inhibit retrograde movement of the connector from the port.

Abstract: Embodiments disclosed herein are directed to a stem including optimized geometry configured to maximize fluid flow while facilitating engagement with a lumen of a catheter. The stem can define a lumen having a distal opening defining a first diameter. The tip structure can define a tip structure lumen having a second diameter that is less than the first diameter. The tip structure can include one or more fingers extending longitudinally distally and defining one or more slots. The tip structure can fit within the catheter lumen, facilitating engagement therewith, while the one or more slots can improve fluid flow, providing little or no reduction in fluid flow relative to the distal opening.

Abstract: Embodiments disclosed herein are directed to a port system including a collapsible reservoir and associated methods thereof. The port can include a body defining a reservoir and formed of a compliant material. The port body can transition between an expanded configuration and a collapsed configuration. The port can further include a port stem or a base plate, formed of a rigid or needle impenetrable material. The base plate can be aligned with a floor of the reservoir to prevent an access needle from traversing the bottom surface of the reservoir. The port, or the reservoir, can transition to the collapsed configuration to provide a reduced overall size or outer profile for insertion and/or between access events. The port can require a smaller incision site, required fewer stitches or no stitches at all, improving patient recovery times, patient comfort, reducing scarring and improving aesthetics.

Abstract: Embodiments are directed to a low profile, injectable port system and associated methods of use. The port can define a port lumen extending between an inlet and an outlet and can include a needle penetrable septum or valve structure. The port stem can couple with a lumen of a catheter and optionally include a cathlock. The diameter, cross-sectional area or shape of the port lumen can substantially equal that of the catheter lumen in a relaxed state. Further the port lumen can define a straight axis and can be aligned with an axis of the catheter lumen. As such, the port can reduce fluid flow resistance between the port and the catheter. The outer profile of the port can substantially equal that of the catheter outer profile. As such, placing the port subcutaneously can require a smaller incision site, improving recovery times and aesthetics.

Abstract: Embodiments disclosed herein are directed to a port system including a body defining a reservoir and a port stem. One of the body or the stem can be formed of a shape memory material and can be transitionable between an expanded configuration and a collapsed configuration. One of the port body or the reservoir in the collapsed configuration can provide a reduced overall size or outer profile of the port for subcutaneous placement and/or between access events. The port can require a smaller incision site, required fewer stitches or no stitches at all, improving patient recovery times, patient comfort, reducing scarring and improving aesthetics. The port stem in collapsed configuration can be smaller than a catheter lumen diameter and can transition to an expanded configuration that is larger than a catheter lumen diameter facilitating a fluid tight seal therebetween.

Abstract: Embodiments disclosed herein are directed to a port system including a body defining a reservoir and a stem. One of the body can include a lower housing and an upper housing slidably engaged therewith and be transitionable between an expanded configuration and a collapsed configuration. The port body in the collapsed configuration can define a smaller volume or outer profile than the port body in the expanded configuration. The reservoir in the collapsed configuration can define a smaller volume than the reservoir in the expanded configuration. A biasing member can bias the port to the expanded configuration. A latching mechanism can retain the port in one of the expanded configuration or the collapsed configuration. An actuator can transition latching mechanism between a locked position and an unlocked position. Subcutaneous placement of the port in the collapsed configuration can require a smaller incision site, fewer stitches and improved patient recovery times.
