Abstract:
A method for occluding or coating a space within a body or tissue lumen comprising:providing a delivery system 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, 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, the catheter configured to inject first and second fluent prepolymer solutions that crosslink when mixed, the first and second lumens configured so that the premature crosslinking of the first and second prepolymer solutions does not occur within the catheter;positioning the distal end of the delivery system at a desired location in the space;providing first and second fluent prepolymers;injecting the first and second fluent prepolymers via the delivery system into the space;crosslinking the first and second prepolymer solutions to form a hydrogel in situ in the space; andwithdrawing the delivery system from the space.
