  • Patent number: 9827411
    Abstract: A bi-directional valve assembly, including valves for use in closed-ended catheters or other elongate tubular devices, is disclosed. In one embodiment, a catheter assembly for insertion into a body of a patient is disclosed and comprises an elongate catheter tube including an outer wall that at least partially defines at least one lumen that extends between a proximal end and a closed distal end thereof. The catheter tube includes a valve assembly that in turn includes a linear slit valve defined through the outer wall of a distal segment of the catheter tube, and a deformation region. The deformation region includes a compliant segment disposed in the outer wall of the catheter tube and a thinned portion of the outer wall. The compliant segment and thinned portion of the deformation region cooperate to preferentially deform the outer wall and open the slit valve during aspiration through the catheter tube.

  • Publication number: 20170281029
    Abstract: A catheter placement system for positioning a catheter in a vasculature of a patient using at least two different modalities. The catheter placement system includes a console with a display, a stylet removably positionable within a lumen of the catheter, a tip location sensor, and an external electrode. The stylet may include an electrocardiogram (ECG) sensor assembly for detecting ECG signals of a node of a heart of the patient, and a first connector in communication with the ECG sensor assembly. The tip location sensor may be configured to detect the stylet when the catheter is disposed within the vasculature of the patient, and to communicate information of the stylet to the console. The console may be configured to receive at least one aspect of the ECG signal detected by the ECG sensor assembly indicative of proximity of the ECG sensor assembly to the node.

  • Publication number: 20170231700
    Abstract: An integrated catheter placement system for accurately placing a catheter within a patient's vasculature is disclosed. In one embodiment, the integrated system comprises a system console, a tip location sensor for temporary placement on the patient's chest, and an ultrasound probe. The tip location sensor senses a magnetic field of a stylet disposed in a lumen of the catheter when the catheter is disposed in the vasculature. The ultrasound probe ultrasonically images a portion of the vasculature prior to introduction of the catheter. ECG signal-based catheter tip guidance is included in the integrated system to enable guidance of the catheter tip to a desired position with respect to a node of the patient's heart. Various methods for establishing a conductive pathway between a sterile field of the patient and a non-sterile field are also disclosed.

  • Publication number: 20140378942
    Abstract: An access port for subcutaneous implantation into a body of a patient is disclosed. The port is typically subcutaneously connected to a catheter, a distal portion of which is disposed within a vein or other vessel of the patient. The port is configured with enhanced fluid handling features to improve fluid flow therethrough while reducing the likelihood of clotting or occlusions in the attached catheter, thus improving system patency. In one embodiment, for instance, an implantable access port is disclosed and comprises a body defining a reservoir, a needle-penetrable septum covering an opening to the reservoir, a stem defining an outlet to the reservoir, and a deformable element included in the reservoir. The deformable element is operably connected to a main portion of the septum and deforms in response to displacement of the septum to counteract a change in volume within the reservoir and prevent blood ingress into the catheter.

  • Publication number: 20130338503
    Abstract: An ultrasound imaging device including the ability to determine when a component, such as a removable probe cap, is attached to a portion of an ultrasound probe. Such a cap is employed in one embodiment to act as a spacer component to provide a standoff for the probe head. Detection of probe cap attachment to the ultrasound probe enables the resultant ultrasound image to be adjusted automatically by the ultrasound imaging system. In one embodiment, an ultrasound imaging system comprises an ultrasound probe, a cap or other component that is attachable to the probe, and a component attachment detection system for detecting attachment of the component to the probe. Once the cap is detected, an aspect of an ultrasound image produced by the imaging system is modified, such as cropping the image to remove undesired portions of the cap, such as the spacer component.
