Apparatus and method for developing an anatomic space for laparoscopic hernia repair and patch for use therewith
First Claim
1. An expansible tunneling apparatus for creating an anatomic working space in a body comprising:
- a substantially rigid tubular member having a bore therein and an open distal end;
a rigid tunneling shaft having a blunt distal end for tunneling bluntly through tissue in the body, said rigid shaft slidably receivable in said bore of said tubular member;
a first obturator slidably mounted on said tunneling shaft and having a rounded distal tip;
a second obturator mounted on a distal end of said tunneling shaft, said first and second obturators being of a size so that said first and second obturators can pass through said bore;
a balloon carried by said tunneling shaft during tunneling through tissue;
a releasable sheath surrounding at least a portion of said balloon, when deflated; and
means for inflating said deflated balloon after tunneling to a desired location to create the anatomic working space.

Abstract
Laparoscopic apparatus and method for insertion into a space or potential space in a body including an introducer device having a tubular member with a bore extending therethrough. A tunneling shaft assembly is provided and is slidably mounted in the bore of the introducer device. The tunneling shaft assembly includes a tunneling shaft having proximal and distal extremities. A tunneling member is mounted on the distal extremity of the tunneling shaft. A balloon assembly is provided which is removably secured to the tunneling shaft. The balloon assembly includes a balloon wrapped about said tunneling shaft. A sheath is provided which encloses the balloon on the tunneling shaft. The sheath has a slit extending longitudinally thereof permitting the sheath to be removed whereby the balloon can be released and inflated. A tubular member is provided which has a balloon inflation lumen thereon and is coupled to the balloon for inflating said balloon.

17. An expansible tunneling apparatus for creating an anatomic working space in a body comprising:
-
a substantially rigid tubular member having a bore therein and an open distal end;
a rigid tunneling shaft having a blunt distal end for tunneling bluntly through tissue in the body, said rigid shaft slidably receivable in said bore of said tubular member wherein said blunt distal end of said tunneling shaft extends through and beyond said open distal end to form, together with said tubular member, a blunt-tipped obturator for tunneling through tissue in the body;
