Abstract
Abstract The present invention relates to a stent delivery system, including a tubular stent delivery catheter (a "shuttle") comprising an expandable deployment segment, onto which a stent can be mounted in a contracted conformation. Unlike hitherto known delivery catheters, however, the deployment segment is expanded by an ancillary device, for example, by a balloon catheter separate and distinct from the shuttle.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
85 words
A shuttle for delivering a stent in a patient comprising a tubular catheter having a proximal end and a distal end and having, at the distal end of the tubular catheter, a deployment segment, wherein the deployment segment comprises an expandable portion flanked, on both sides, by reenforced regions that are less expandable than the expandable portion, such that the deployment segment is capable of being expanded by means of a separate balloon catheter to deliver the stent in a desired location in the patient.
Claim 2
Dependent Claim
85 words
A shuttle for delivering a stent in a patient comprising a tubular catheter having a proximal end and a distal end and having, at the distal end of the tubular catheter, a deployment segment, wherein the deployment segment comprises an expandable portion flanked, on both sides, by reenforced regions that are less expandable than the expandable portion, such that the deployment segment is capable of being expanded by means of a separate balloon catheter to deliver the stent in a desired location in the patient.
Claim 3
Dependent Claim
14 words
The shuttle of claim 1, wherein a stent is mounted on the deployment segment.
Claim 4
Dependent Claim
12 words
The shuttle of claim 2, wherein the stent is a self-expanding stent.
Claim 5
Dependent Claim
12 words
The shuttle of claim 2, wherein the stent is a non-self-expanding stent.
Claim 6
Dependent Claim
12 words
The shuttle of claim 4, wherein the stent is a Palmaz-Schatz stent.
Claim 7
Dependent Claim
19 words
The shuttle of claim 1, further comprising an embolic filter attached to the distal end of the tubular catheter.
Claim 8
Dependent Claim
16 words
The shuttle of claim 1, wherein the deployment segment comprises a pharmaceutical substance in releasable form.
Claim 9
Dependent Claim
130 words
A stent delivery system comprising (a) a shuttle for delivering a stent in a patient comprising a tubular catheter having a proximal end and a distal end and having, at the distal end of the tubular catheter, a deployment segment wherein the deployment segment comprises an expandable portion flanked, on both sides, by reenforced regions that are less expandable than the expandable portion; (b) a stent mounted on the expandable portion of the deployment segment; and (c) a balloon catheter having a shaft and comprising a balloon at its distal end; wherein the deployment segment is capable of being passed over the shaft of the balloon catheter and its expandable portion may be expanded by inflation of the balloon to deliver the stent in a desired location in the patient.
Claim 10
Dependent Claim
130 words
A stent delivery system comprising (a) a shuttle for delivering a stent in a patient comprising a tubular catheter having a proximal end and a distal end and having, at the distal end of the tubular catheter, a deployment segment wherein the deployment segment comprises an expandable portion flanked, on both sides, by reenforced regions that are less expandable than the expandable portion; (b) a stent mounted on the expandable portion of the deployment segment; and (c) a balloon catheter having a shaft and comprising a balloon at its distal end; wherein the deployment segment is capable of being passed over the shaft of the balloon catheter and its expandable portion may be expanded by inflation of the balloon to deliver the stent in a desired location in the patient.
Claim 11
Dependent Claim
21 words
The stent delivery system of claim 8, further comprising an embolic filter attached to the distal end of the tubular catheter.
Claim 12
Independent Claim
198 words
A method for placing a stent in a vasel of a patient wherein the vessel contains an obstruction, comprising (i) introducing a balloon catheter, having a shaft and comprising a balloon at its distal end, into the vessel such that the balloon is within the obstruction; (ii) inflating the balloon so as to dilate the obstruction; (iii) deflating the balloon; (iv) advancing the balloon distal to the obstruction; (v) passing a shuttle, comprising a tubular catheter having a proximal end and a distal end and having, at the distal end of the tubular catheter, a deployment segment wherein the deployment segment comprises an expandable portion flanked, on both sides, by reenforced regions that are less expandable than the expandable portion, and wherein a stent is mounted on the expandable portion of the deployment segment, over the balloon catheter, such that the stent is positioned within the dilated obstruction; (vi) withdrawing the deflated balloon into the shuttle such that the balloon lies within the deployment segment; (vii) inflating the balloon, thereby expanding the expandable portion of the deployment segment and delivering the stent within the dilated obstruction; and (viii) withdrawing the shuttle and the balloon catheter from the patient.
Claim 13
Independent Claim
198 words
A method for placing a stent in a vasel of a patient wherein the vessel contains an obstruction, comprising (i) introducing a balloon catheter, having a shaft and comprising a balloon at its distal end, into the vessel such that the balloon is within the obstruction; (ii) inflating the balloon so as to dilate the obstruction; (iii) deflating the balloon; (iv) advancing the balloon distal to the obstruction; (v) passing a shuttle, comprising a tubular catheter having a proximal end and a distal end and having, at the distal end of the tubular catheter, a deployment segment wherein the deployment segment comprises an expandable portion flanked, on both sides, by reenforced regions that are less expandable than the expandable portion, and wherein a stent is mounted on the expandable portion of the deployment segment, over the balloon catheter, such that the stent is positioned within the dilated obstruction; (vi) withdrawing the deflated balloon into the shuttle such that the balloon lies within the deployment segment; (vii) inflating the balloon, thereby expanding the expandable portion of the deployment segment and delivering the stent within the dilated obstruction; and (viii) withdrawing the shuttle and the balloon catheter from the patient.
