Interventional catheters incorporating aspiration and/or infusion systems

摘要

An interventional catheter assembly comprising a catheter for insertion and guidance to a target site in a body lumen or a cavity and an operating head mounted in proximity to a distal end of the catheter and comprising a system for removing obstructive material from the target site is provided. In certain embodiments, the catheter assembly includes at least one aspiration port located proximal to the operating head that communicates with a first sealed lumen for withdrawing fluids and obstructive material from the target site. The catheter assembly may also include at least one liquid infusion port that communicates with a second sealed lumen for supplying fluid to a location in proximity to the target site. Kits including the interventional catheter assembly with an aspiration and/or infusion conduit are also provided.

1. An interventional catheter assembly comprising:
(a) a flexible catheter having an integrated infusion lumen and an integrated aspiration lumen for insertion and guidance through a body lumen or cavity to a target site in a body; (b) an operating head mounted in proximity to a distal end of the catheter and comprising a system for removing unwanted material from the target site; (c) at least one aspiration port located proximal to the operating head, wherein the at least one aspiration port is in communication with the integrated aspiration lumen for withdrawing fluids and unwanted materials from the target site; and (d) at least one infusion port located distal to the operating head, proximal to the operating head, or through the operating head and in communication with the integrated infusion lumen.
