Abstract
Abstract Disclosed is a Low Profile Perfusion Catheter, for use in coronary angioplasty applications. Preferably, the catheter is provided with an inflatable dilatation balloon, and a perfusion lumen extending therethrough. The diameter of the perfusion lumen is enlargable from a first, reduced diameter to a second, enlarged diameter. In one embodiment, an axially movable tubular support is movable within the lumen from a proximal, insertion position to a distal perfusion position. In another embodiment, the support is radially expandable. In a further embodiment, a porus drug delivery balloon is provided.
