Abstract: The present invention relates to a multi-reservoir port, catheter, and non-coring needle system that supports high-flow applications such as hemodialysis and apheresis. In particular, the invention relates to improvements to provide optimal flow rates, septum life, and septum/needle stability when introducing fluid into the multi-reservoir port.

Abstract: A septum for a port is provided, the septum having a top wall and a side wall. The side wall can include a pressure-activated valve element for regulating the flow of fluid across the valve. The curvature of the side wall and the geometry of the sidewall and the housing can be tailored to bias the valve element to open at different pressures during infusion and aspiration. The side wall can also include an extended portion that can function as a suture wing for securing the port within a port pocket.

Abstract: The present invention relates to a multi-reservoir port, catheter and non-coring needle systems that support high-flow applications such as hemodialysis and apheresis. In particular, the present invention relates to improvements to each of these systems to provide optimal flow rates and septum life with minimal intraluminal pressure; both individually and in combination.

Abstract: A system and method for catheter placement using ECG is provided. In certain embodiments, the system and method can generate a patient specific window for tracking a characteristic of an ECG waveform, such as the amplitude of a P-wave. The patient specific window can be utilized in a system and method for assisting in the placement of a catheter within a patient. In other embodiments, a tip location algorithm can be used with an anti-thrombogenic catheter and an intravascular electrode assembly for maintaining a high resolution intravascular signal in an ECG based catheter tip placement system.

Abstract: A catheter having a shaft with a substantially circular profile and a catheter channel on the inner wall spiraling about the catheter longitudinal axis. In some embodiments, the catheter has multiple catheter channels spiraling about the catheter longitudinal axis. Certain embodiments include the catheter as part of a system, including an implantable port system with a rifled port outlet stem, and an infusion system with a rifled syringe distal component.

Abstract: Systems and methods for securing a catheter to an implantable port are disclosed. The system includes a collar having a catheter gripping protrusion and a port lock cavity. A port having an outlet stem with a constant cross-sectional profile is utilized. The collar is configured to mate with a port lock protrusion connected to the port.

Abstract: Pressure activated valves for catheters with improved tolerance of high pressure and high flow conditions are described. Embodiments of the valve comprise a flexible membrane with one or more linear slits therethrough, and means for applying tension to the flexible membrane in-line with the linear slits. The application of tension may optionally be facilitated by structural features of both the flexible membrane and the valve housing.
