Apparatus and method for developing an anatomic space for laparoscopic hernia repair and patch for use therewith
First Claim
1. An introducer and sheath assembly comprising:
- an elongate introducer member, a tubular sheath adapted to surround said introducer member, said tubular sheath having a weakened region which extends along its longitudinal axis from a proximal region to a distal region of said tubular sheath; and
a handle on the proximal region of said tubular sheath, said handle being adapted to be pulled proximally, thereby causing said weakened region to separate as said weakened region is drawn against said introducer member, thereby allowing said tubular sheath to be removed from said introducer member, said handle having one-or more inwardly directed latches adapted to releasably secure said sheath to said introducer member, wherein said one or more latches comprise one or more protuburances formed on an inner wall of said handle and wherein said introducer member comprises one or more recesses, said one or more protuberances being adapted to releasably engage said one or more recesses.

Abstract
Apparatus for creating an anatomic spade in tissue in a body comprising an introducer device having a tubular member with a bore extending therethrough. A tunneling shaft assembly is slidably mounted in the bore of the introducer device. The tunneling shaft assembly includes a tunneling shaft having proximal and distal extremities. A blunt tip is secured to the distal extremity of the tunneling shaft. A balloon assembly is provided. The balloon assembly is removably secured to the tunneling shaft. The balloon assembly includes a deflated collapsed balloon. A sheath encloses the balloon and is carried by the tunneling shaft. The sheath has a weakened region extending longitudinally thereof permitting the sheath to be removed to release the balloon.

7. An introducer and sheath assembly comprising:
-
an elongate introducer member, a tubular sheath adapted to surround said introducer member, said tubular sheath having a weakened region which extends along its longitudinal axis from a proximal region to a distal region of said tubular sheath; and
a handle on the proximal region of said tubular sheath, said handle being adapted to be pulled proximally, thereby causing said weakened region to separate as said weakened region is drawn against said introducer member, thereby allowing said tubular sheath to be removed from said introducer member, said handle having one or more inwardly directed detents for releasably securing the sheath to said member, wherein said one or more detents are formed on an inner wall of said handle and wherein said introducer member comprises one or more recesses, said one or more detents being adapted to releasably engage said one or more recesses. - View Dependent Claims (8, 9, 10, 11, 12)
