Claim 1
Independent Claim
202 words
A system for the delivery of an expandable stent within a body lumen over a guiding member comprising: a) an elongated sheath having proximal and distal ends, an inner lumen extending therein, a first port in the distal end and a second port spaced proximally from the distal end, both of the ports being in fluid communication with the inner lumen; b) an elongated catheter disposed within the inner lumen of the sheath having proximal and distal ends, an expandable member proximally adjacent to the distal end of the catheter which is adapted to receive on the exterior thereof an expandable stent, and an inner lumen which is adapted to slidably receive a guiding member therein and which extends between a first port in the distal end of the catheter and a second port spaced proximally from the distal end of the catheter, both of the ports being in fluid communication with the inner lumen of the catheter; and c) means to adjust the relative axial positions of the catheter and the sheath to expose the expandable member on the catheter so that upon the expansion of the expandable member an expandable stent disposed about the expandable member will thereby be expanded.
Claim 2
Dependent Claim
25 words
The stent delivery system of claim 1 wherein the sheath has a wall with a slit therein extending between the first and second ports thereof.
Claim 3
Dependent Claim
32 words
The stent delivery system of claims 1 or 2 wherein the catheter has a wall with a slit therein extending from the second port to a location proximal to the expandable member.
Claim 4
Dependent Claim
115 words
The stent delivery system of any one of the preceding claims wherein the means to adjust the relative axial positions of the dilatation catheter and the sheath includes a manipulator comprising: an elongated housing having proximal and distal ends and an interior chamber; a cap which has a threaded passageway therethrough and which is rotatably mounted on an end of the elongated housing; and a longitudinally movable drive member which has a threaded exterior, which is disposed at least partially within the interior chamber of the elongated housing and which has a distal end extending through the central passageway of the cap, rotation of the cap causing movement of the axial movement of drive member.
Claim 5
Dependent Claim
25 words
The stent delivery system of claim 4 wherein the longitudinally movable drive member has a central passageway which receives the proximal end of the catheter.
Claim 6
Dependent Claim
20 words
The stent delivery system of claim 5 wherein the proximal end of the catheter is fixed to the manipulator housing.
Claim 7
Dependent Claim
33 words
The stent delivery system of claims 5 or 6 wherein the sheath is fixed to the distal end of the longitudinally movable drive member which extends out the distal end of the manipulator.
Claim 8
Dependent Claim
162 words
A kit for the delivery of a stent within a body lumen comprising: a) an elongated sheath having proximal and distal ends, an inner lumen extending therein, a first port in the distal end and a second port spaced proximally from the distal end, both of the ports being in fluid communication with the inner lumen; b) an elongated catheter adapted to be disposed within the inner lumen of the sheath having proximal and distal ends, an expandable member proximally adjacent to the distal end of the catheter which is adapted to receive on the exterior thereof an expandable stent, an inner lumen which is adapted to receive a guiding member therein and which extends between a first and second ports of the catheter; and c) means to adjust the relative axial positions of the catheter and the sheath to expose the expandable member so that upon the expansion thereof an expandable stent disposed about the expandable member will thereby be expanded.
Claim 9
Dependent Claim
28 words
The stent delivery system kit of claim 8 including an expandable stent which is adapted to be mounted on the exterior of the expandable member on the catheter.
Claim 10
Dependent Claim
27 words
The stent delivery system of claims 8 or 9 wherein the sheath has a wall with a slit therein extending between the first and second ports thereof.
Claim 11
Dependent Claim
33 words
The stent delivery system of claims 8, 9 or 10 wherein the catheter has a wall with a slit therein extending from the second port to a location proximal to the expandable member.
