Abstract
Abstract Methods and apparatus of forming hydrogel systems in situ are provided using a delivery system configured to deliver two or more fluent prepolymer solutions without premature crosslinking. The delivery system comprises separate first and second lumens coupling first and second inlet ports and first and second outlet ports, respectively, and may include a balloon, flexible distal region, mixing chamber or steerable distal end. Multi-component hydrogel systems suitable for use with the inventive methods and apparatus are also described.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
127 words
Apparatus for depositing a polymer within a space within a body comprising: a catheter having proximal and distal ends, first and second inlet ports disposed at the proximal end, first and second outlet ports disposed at the distal end adjacent to a balloon adapted to anchor within the space, a first lumen coupling the first inlet port to the first outlet port, and a second lumen coupling the second inlet port to the second outlet port, wherein the catheter is configured to inject into the space first and second fluent solutions that crosslink when mixed, the first and second solutions injected through the first and second lumens, respectively, the first and second lumens configured so that premature crosslinking of the solutions does not occur within the catheter.
Claim 2
Dependent Claim
127 words
Apparatus for depositing a polymer within a space within a body comprising: a catheter having proximal and distal ends, first and second inlet ports disposed at the proximal end, first and second outlet ports disposed at the distal end adjacent to a balloon adapted to anchor within the space, a first lumen coupling the first inlet port to the first outlet port, and a second lumen coupling the second inlet port to the second outlet port, wherein the catheter is configured to inject into the space first and second fluent solutions that crosslink when mixed, the first and second solutions injected through the first and second lumens, respectively, the first and second lumens configured so that premature crosslinking of the solutions does not occur within the catheter.
Claim 3
Dependent Claim
20 words
The apparatus as defined in claim 1 wherein the catheter is configured to be transcervically inserted into a fallopian tube.
Claim 4
Dependent Claim
43 words

Claim 5
Dependent Claim
31 words
The apparatus as defined in claim 1 wherein one of the first and second lumens is adapted to accept a guidewire to assist in placing the distal end within the space.
Claim 6
Dependent Claim
30 words
The apparatus as defined in claim 1 wherein a distal region of the catheter comprises a flexible material that permits the distal end of the catheter to be flow directed.
Claim 7
Dependent Claim
