INTERVENTIONAL CATHETERS INCORPORATING ASPIRATION AND/OR INFUSION SYSTEMS
First Claim
1. An interventional catheter assembly comprising:
- (a) a catheter for insertion and guidance 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 a target site in a body lumen or cavity;
(c) at least one aspiration port located proximal to the operating head, wherein the at least one aspiration port extends over at least 20% of a circumference of the catheter and is in communication with an aspiration lumen for withdrawing fluids and unwanted materials from the target site; and
(d) at least one liquid infusion port provided in proximity to the operating head, wherein the at least one infusion port is in communication with an infusion lumen for infusing liquid through the infusion port.

Abstract
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, together with at least one liquid infusion port penetrating the catheter and located proximal to the at least one aspiration port that communicates with a second sealed lumen for supplying fluid to a location in proximity to the target site.

17. An interventional catheter assembly comprising:
- a catheter for insertion and guidance to a target site in a body;
an operating head mounted in proximity to a distal end of the catheter, the operating head being operable to remove unwanted material from body lumens or cavities;
at least one aspiration port located proximal to the operating head, wherein the at least one aspiration port extends over at least 20% of a circumference of the catheter and is in communication with a first sealed lumen for withdrawing fluids and obstructive material from the target site; and
at least one liquid infusion port provided in proximity to the operating head, wherein the at least one infusion port is in communication with a second sealed lumen for infusing liquid through the infusion port, whereby the interventional catheter assembly, when the aspiration lumen is in operable communication with an aspiration system and the infusion lumen is in operable communication with an infusion system, is capable of operating to provide an infusion rate of about 45-150 ml/min and an aspiration rate of about 20-90 ml/min.
- a catheter for insertion and guidance to a target site in a body;
