    Abstract: An improved laparoscopic apparatus for tunneling to a desired anatomical location and developing a surgical space is disclosed, including a tunneling member adapted to receive a laparoscope therein and an inflatable balloon secured on the tunneling member. The tunneling member has a passage extending between its open proximal and distal ends. A lip is integrally formed on the distal end to retain a laparoscope inserted into the passage, the lip having a substantially rounded and blunt distal edge. The lip defines a recessed or open center area in the distal opening, enhancing the field of view of the laparoscope therethrough. The balloon is formed from flexible, transparent material, and is rolled and secured to the tunneling member. The balloon includes inverted seams and/or unfused outer edges adapted to minimize tissue trauma during inflation, and has an extended distal portion adapted to be unrolled during space development, thereby improving distal space development and enhancing visualization of landmarks within the space being developed.

    Abstract: A 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.
