International ClassA61M 031/00AbstractA catheter and method of using the catheter for the delivery of therapeutic or diagnostic liquid within a body lumen of a patient. The catheter has an outer inflatable member which has a wall with a plurality of apertures which eject therapeutic or diagnostic liquid in a jet-like form deep within the lumenal tissue adjacent to the outer inflatable member. In one embodiment the catheter has an inner inflatable member disposed within the outer inflatable member which upon inflation expands the outer tubular member so as to dilatate a stenotic region of a body lumen such as an artery. The inflatable member may be provided with proximal and distal ends which expand to larger diameters than the central inflatable section so as to seal the larger ends and prevent the loss of fluid. | |
