  • Patent number: 11918758
    Abstract: A catheter assembly for use in accessing a vasculature of a patient is disclosed. In one embodiment, the catheter assembly includes a catheter body that includes a flattened oval outer surface and defines first and second lumens. The catheter body defines a distal tip region that includes a venous lateral opening that is in fluid communication with the first lumen and includes a distal-facing portion. The distal tip region further includes an arterial lateral opening that is in fluid communication with the second lumen, includes a distal-facing portion, and is substantially un-staggered with respect to the venous lateral opening. A distal end opening is in fluid communication with a power injectable third lumen. In another embodiment, the first and second lumens each generally include a reniform cross-sectional shape. In yet another embodiment, a dual-lumen catheter includes first and second lumens that each define a modified ellipse cross-sectional shape.

  • Patent number: 11759615
    Abstract: An access port for providing subcutaneous access to a patient is disclosed. In one embodiment, the port includes an internal body defining a fluid cavity that is accessible via a septum. A compliant outer cover including silicone is disposed about at least a portion of the body. A flange is included with the port body and is covered by the outer cover. The flange radially extends about a perimeter of the port body proximate the septum so as to impede penetration of a needle substantially into the outer cover in instances where the needle misses the septum. The flange can further include both an anchoring feature for securing the outer cover to the port body and an identification feature observable via x-ray imaging technology for conveying information indicative of at least one attribute of the access port. The outer cover provides a suitable surface for application of an antimicrobial/antithrombotic coating.

  • Patent number: 11633566
    Abstract: A pre-curved catheter tube of a catheter assembly or other elongate medical device and methods for forming such a device using a heating procedure is disclosed. Pre-curving of the catheter tube is desirable to impart to the catheter assembly a desired positional configuration when the catheter assembly is inserted into a patient. The heating procedure may include heat sterilization procedures commonly used to sterilize medical devices prior to use. One method for curving a catheter tube of a catheter assembly includes constraining the catheter tube into a curved configuration using the tube constraint, heating the catheter tube in the curved configuration for a predetermined time at a predetermined temperature, and releasing the catheter tube from the tube constraint after the heating is complete.

  • Patent number: 10973497
    Abstract: Provided herein are systems, devices, and methods for sample collection. A sample collection device may comprise a vessel, a lid, and pre-loaded liquid solutions. The sample collection device may collect a liquid sample, such as a biological sample. The liquid solutions may comprise reagents for preserving and/or stabilizing biological samples, such as saliva, collected in the vessel. A chamber comprising the liquid solutions may be located in the vessel and/or the lid. In some instances, the liquid solution may be released from the chamber upon closure of the vessel with the lid. In some instances, the liquid solution may be released from the chamber upon actuation of an implement, such as a plunger. In some instances, the liquid solution may be released upon compression of an absorbent member. The sample collecting device may be delivered to a remote location for further processing and/or analysis.

  • Publication number: 20210077801
    Abstract: A power-injectable access port can include a power-injectable access port cap including an opening and a power-injectable access port base including a reservoir corresponding to the opening. The power-injectable access port can further include a septum corresponding to the reservoir. The septum can include a bottom surface covering the reservoir and a top surface extending through the opening in the power-injectable access port cap. The power-injectable access port can include a radiopaque identification feature indicating that the power-injectable access port is suitable for power injection. The radiopaque identification feature can be a suspension of a radiopaque material in a silicone material positioned on an outer surface of the power-injectable access port base.

  • Patent number: 10857340
    Abstract: A power-injectable access port and methods of making are described. One method of making includes forming a power-injectable access port housing, creating a screen including one or more apertures through the screen in the shape of one or more alphanumeric characters, suspending a radiopaque material in a silicone material to form a radiopaque suspension, and depositing the radiopaque suspension onto a surface of the power-injectable access port housing through the one or more apertures of the screen to create at least one radiopaque identification feature. The at least one radiopaque identification feature may have a thickness protruding from an outer surface of the port base such that it is perceivable by sight and touch prior to implantation of the power injectable access port, and is observable via imaging technology subsequent to subcutaneous implantation of the power-injectable access port.

  • Patent number: 10729846
    Abstract: A needle assembly to prevent fluid/vapor escape so as to reduce or prevent fluid exposure to a clinician during use of the needle assembly. The needle assembly may include a handle portion with a needle extending therefrom, and a base portion releasably coupled to the handle portion. The base portion may include a safety assembly to shield a distal tip of the needle and prevent user contact therewith. The base portion may further include a self-sealing pad covering a bottom external surface thereof. The self-sealing pad may include an upper surface designed to mate with the base portion and a raised portion compressively positioned in the opening of the bottom external surface. The needle assembly may further include a fluid isolation component.

  • Publication number: 20190231172
    Abstract: Disclosed herein are connection systems for establishing electrical connections across a sterile field. An example connection system includes a sensor connector, a probe connector, and a tether having a first end connected to the sensor connector and a second end connected to the probe connector. The sensor connector includes a piercing element. The piercing element is configured to pierce a sterile side of a drape and establish a first electrical connection with a receptacle of a sensor when the piercing element is inserted into the receptacle. The probe connector includes a probe-connecting means configured for a user to establish a second electrical connection between an electrical contact of the probe connector and a wire probe. The tether is configured to convey electrical signals between the sensor connector and the probe connector. Also disclosed herein are methods of connection systems for establishing electrical connections across a sterile field.
