Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
201 words
A tunnelling apparatus for creating an anatomic
working space between tissue layers in a body comprising: a tubular member (33) having a bore extending
therethrough to provide an open distal end; a substantially rigid tunnelling shaft (47) having a
blunt distal tip (79) for tunnelling bluntly through tissue,
said tunnelling shaft (47) being slidably receivable in said
bore of said tubular member (33); a deflated balloon (87) formed into a roll surrounding
said tunnelling shaft (47) during tunnelling through tissue; means (101) carried by said balloon (87) for removably
securing said balloon (87) to said tunnelling shaft (47); a removable sleeve (106) surrounding at least a portion
of said deflated balloon (87) and said tunnelling shaft (47),
said sleeve (106) being provided with a weakened region (108)
extending longitudinally thereof to permit said sleeve (106)
to separate from said deflated balloon (87) thereby releasing
said balloon (87); and means for inflating said deflated balloon (87) after
tunnelling to a desired location within the body to cause
said balloon (87) to progressively unroll and attempt to
lie in a plane and to expand to create separation forces
between the tissue layers generally perpendicular to said plane
to create the anatomic working space.
Claim 2
Dependent Claim
18 words
The apparatus of claim 1 wherein said balloon (87)
is a non-elastomeric balloon (87) having a predetermined
shape.
Claim 3
Dependent Claim
15 words
The apparatus of claim 2 therein said balloon (87)
is formed from an plastic material.
Claim 4
Dependent Claim
18 words
The apparatus of claim 1 further comprising means
for introducing an insufflation fluid into the created
working space.
Claim 5
Dependent Claim
36 words
The apparatus of claim 1 wherein said inflation
means comprises a flexible tubular member (96) extending
from said balloon (87) and a fitting (98) attached to said
tubular member (96) for connecting to an inflation source.
Claim 6
Dependent Claim
31 words
The apparatus of claim 1 further comprising an
introducer member (51) having a bore extending therethrough,
said tunnelling shaft (47) being slidably mounted in said
bore of said introducer member (51).
