Abstract
Abstract An apparatus for creating an anatomic space in tissue in a body includes 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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
99 words
A balloon assembly for use with a tunneling member comprising: a first sheet and a second sheet of a material which is substantially inelastic within a predetermined range of inflation pressures, said first and second sheets each having outer margins, said outer margins being bonded together to form a balloon having an enclosed space; a sleeve on said balloon for receiving the tunneling member; and a tubular member extending into said ballon for introducing a balloon inflation medium into said enclosed space to inflate said balloon to a predetermined size and shape, as determined by said substantially inelastic material.
Claim 2
Dependent Claim
99 words
A balloon assembly for use with a tunneling member comprising: a first sheet and a second sheet of a material which is substantially inelastic within a predetermined range of inflation pressures, said first and second sheets each having outer margins, said outer margins being bonded together to form a balloon having an enclosed space; a sleeve on said balloon for receiving the tunneling member; and a tubular member extending into said ballon for introducing a balloon inflation medium into said enclosed space to inflate said balloon to a predetermined size and shape, as determined by said substantially inelastic material.
Claim 3
Dependent Claim
14 words
The balloon assembly of claim 1 wherein said balloon is generally oval-shaped when inflated.
Claim 4
Dependent Claim
14 words
The balloon assembly of claim 1 wherein said balloon is generally rectangular when inflated.
Claim 5
Dependent Claim
21 words
The balloon assembly of claim 1 further comprising means on said sleeve for releasably securing the tunneling member to said balloon.
Claim 6
Dependent Claim
46 words
The balloon assembly of claim 4 wherein said means on said sleeve for releasably securing the tunneling member to said balloon comprises a weakened region extending longitudinally along said sleeve, said weakened region being separable to permit said balloon to be separated from the tunneling member.
Claim 7
Dependent Claim
20 words
The balloon assembly of claim 5 wherein said weakened region is formed from a series of longitudinally spaced apart perforations.
Claim 8
Dependent Claim
26 words
The balloon assembly of claim 1 wherein said sleeve extends longitudinally along said balloon and is spaced substantially equidisant from said outer margins of said sheets.
Claim 9
Dependent Claim
30 words
The balloon assembly of claim 1 wherein each of the said outer margins of said sheets is gathered toward a central axis of said balloon when said balloon is deflated.
Claim 10
Dependent Claim
24 words
The balloon assembly of claim 8 further comprising a balloon cover for retaining said balloon in a tightly gathered relationship about the tunneling member.
Claim 11
Dependent Claim
28 words
The balloon assembly of claim 9 wherein said balloon cover is a relatively flexible tubular member which surrounds said balloon and which may be separated from said balloon.
Claim 12
Dependent Claim
22 words
The balloon assembly of claim 1 wherein said balloon has a distally extending protrusion formed in a distal region of said balloon.
Claim 13
Dependent Claim
26 words
A balloon assembly as in claim 1 wherein said first sheet has an upper surface and at least a portion of said upper surface is roughened.
