1. A system for removing unwanted material from a body lumen or cavity comprising:
- (a) a catheter;
(b) an operating head positioned at or near a distal end of the catheter;
(c) at least one infusion port provided near the distal end of the catheter and in proximity to the operating head;
(d) a plurality of tissue penetration members provided as bristle-like structures having a stiffness sufficient to score tissue as they are moved with respect to the tissue and located in proximity to the at least one infusion port, wherein the plurality of tissue penetration members is adapted to contact tissue within a body lumen or cavity to promote uptake of a composition infused through the at least one infusion port, and(e) an inflatable structure adapted to adjust from a smaller diameter delivery condition to a larger diameter deployed condition, wherein the at least one infusion port is provided in the inflatable structure.

Abstract
Systems and methods for delivery of therapeutic and/or diagnostic compositions to an interventional site having diseased or newly treated tissue are provided. Integrated interventional catheter systems incorporating surfaces coated with a therapeutic composition, or tissue penetration members for scoring or disrupting tissue prior to or during administration of a therapeutic composition are provided. Infusion of therapeutic composition(s) may also be provided.
