Abstract: Devices and methods for obtaining high flow rates in a port catheter system, and devices and methods for using a high flow rate port catheter system are disclosed. In one embodiment, a reservoir is dedicated for aspiration and a separate reservoir is dedicated for infusion. Fluid flow channels associated with aspiration are larger than the fluid flow channels associated with infusion. The catheter connected to the port can have an offset tip configuration. Methods for accessing the port are also disclosed.

Abstract: Devices and methods for cleaning a port reservoir are disclosed. The system includes a trocar, cannula and cleaning member. In one embodiment, the cleaning member has scraping members disposed at its distal end for mechanical breakup of thrombus formation. The cleaning member can also have a lumen for infusing anti-coagulant fluid and aspirating loose pieces of thrombus formation.
