Patent ID: 7077821

Claim:
A system for bulking body tissue, comprising: an elongated member comprising a proximal end, a distal end, at least one opening in the distal end, and at least one inner lumen extending from the proximal end to the opening in the distal end; at least one compressible bulking device in the inner lumen of the elongated member, the at least one bulking device being configured to be implanted in body tissue to bulk the tissue; and a pushing device to push the at least one bulking device through the opening in the distal end of the elongated member, wherein the at least one bulking device is expandable from a compressed configuration to an expanded configuration, the at least one bulking device being in the compressed configuration when the at least one bulking device is in the inner lumen and the at least one bulking device expanding to the expanded configuration when the at least one bulking device passes through the opening in the distal end of the elongated member, wherein the at least one bulking device comprises a migration limiting element for limiting migration of the at least one bulking device in the body tissue, and wherein the elongated member comprises a first inner lumen containing the at least one bulking device and a second inner lumen in fluid communication with a source of fluid.
