Abstract
This invention concerns a cystoscope delivery system for implanting a flexible, generally cylindrical, expandable stent. The system comprises a rigid or flexible sheath having distal and proximal ends, the sheath defining a central lumen and at least one secondary lumen extending therethrough and having two longitudinally displaced openings extending from a secondary lumen radially to the surface of the sheath, a rigid cystoscope comprising a distal scope member and a proximal viewing head, the distal scope member extending distally through the central lumen, a flexible, expandable stent having discrete proximal and distal ends, the stent being positioned circumferentially around the sheath, at least one release wire positioned in and extending through the secondary lumen or lumens, and two or three restraining members, two of which are positioned at respective ends of the stent and each having a restraining member extending over a respective end of the stent, the release wire or wires extending through at least one of said openings to hold one or both ends of the stent and thus to hold the stent in position, such that when the release wire or wires are pulled proximally, one or both ends of the stent are released from the restraining members to permit the stent to expand.
