Abstract
Abstract In one embodiment, the stent delivery system comprises an inner catheter. A handle is disposed at the proximal end of the inner catheter, and an enlarged tip is disposed at the distal end thereof. A stent engaging sleeve coaxially surrounds and is secured to a portion of the inner catheter proximally contiguous to the tip. A stent is mounted over the stent engaging sleeve in a longitudinally stretched state and is maintained, until deployment, in the stretched state by a stent restraining sleeve. The stent restraining sleeve, which coaxially surrounds the stent and is appropriately sized to maintain the stent in its stretched state, is a braided tube formed directly over the stent. The system also includes an outer catheter that surrounds much of the distal end of the inner catheter up to its tip, the outer catheter being adapted for axial movement relative to the inner catheter.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
123 words
A method of manufacturing a stent delivery system, said method comprising the steps of: (a) providing an inner catheter; (b) compressing a self-expandable stent over said inner catheter; (c) while said self-expandable stent is in a compressed state, positioning a braided tube around said inner catheter and said self-expandable stent, said braided tube, when thus positioned around said inner catheter and said self-expandable stent, being adapted for axial movement relative to said self-expandable stent and being dimensioned to maintain said self-expandable stent in said compressed state; and (d) positioning an outer catheter around said braided tube such that said braided tube is fixedly attached to said outer catheter tube, and said outer catheter being adapted for axial movement relative to said inner catheter.
Claim 2
Independent Claim
123 words
A method of manufacturing a stent delivery system, said method comprising the steps of: (a) providing an inner catheter; (b) compressing a self-expandable stent over said inner catheter; (c) while said self-expandable stent is in a compressed state, positioning a braided tube around said inner catheter and said self-expandable stent, said braided tube, when thus positioned around said inner catheter and said self-expandable stent, being adapted for axial movement relative to said self-expandable stent and being dimensioned to maintain said self-expandable stent in said compressed state; and (d) positioning an outer catheter around said braided tube such that said braided tube is fixedly attached to said outer catheter tube, and said outer catheter being adapted for axial movement relative to said inner catheter.
Claim 3
Dependent Claim
27 words
The method as claimed in claim 1 wherein said braided tube positioning step comprises sliding a pre-formed braided tube over said inner catheter and said self-expandable stent.
Claim 4
Independent Claim
106 words
A method of manufacturing a stent delivery system, said method comprising the steps of: (a) providing an inner catheter; (b) compressing a self-expandable stent over said inner catheter; (c) while said self-expandable stent is in a compressed state, positioning a braided tube around said inner catheter and said self-expandable stent, said braided tube being dimensioned to maintain said self-expandable stent in said compressed state; and (d) positioning an outer catheter around said braided tube, said outer catheter being adapted for axial movement relative to said inner catheter, wherein said braided tube positioning step comprises forming a braided tube over said self-expandable stent and said inner catheter.
Claim 5
Independent Claim
106 words
A method of manufacturing a stent delivery system, said method comprising the steps of: (a) providing an inner catheter; (b) compressing a self-expandable stent over said inner catheter; (c) while said self-expandable stent is in a compressed state, positioning a braided tube around said inner catheter and said self-expandable stent, said braided tube being dimensioned to maintain said self-expandable stent in said compressed state; and (d) positioning an outer catheter around said braided tube, said outer catheter being adapted for axial movement relative to said inner catheter, wherein said braided tube positioning step comprises forming a braided tube over said self-expandable stent and said inner catheter.
Claim 6
Dependent Claim
21 words
The method as claimed in claim 3 further comprising mechanically coupling said outer catheter to said braided tube for axial movement.
Claim 7
Dependent Claim
42 words
The method as claimed in claim 4 wherein said inner catheter and said self-expandable stent are coaxially disposed, wherein said self-expandable stent is flexible in both the longitudinal and radial axes and wherein said compressing step comprises stretching said self-expandable stent longitudinally.
Claim 8
Dependent Claim
43 words
The method as claimed in claim 5 wherein said outer catheter is provided with a longitudinal slit extending at least a part of the length thereof, said method further comprising, after said outer catheter positioning step, the step of sealing said longitudinal slit.
Claim 9
Independent Claim
120 words
A method of manufacturing a stent delivery system, said method comprising the steps of: (a) providing an inner catheter; (b) compressing a self-expandable stent over said inner catheter; (c) while said self-expandable stent is in a compressed state, positioning a braided tube around said inner catheter and said self-expandable stent, said braided tube being dimensioned to maintain said self-expandable stent in said compressed state; (d) positioning an outer catheter around said braided tube, said outer catheter being adapted for axial movement relative to said inner catheter, wherein said braided tube positioning step comprises sliding a pre-formed braided tube over said inner catheter and said self-expandable stent; and (e) mechanically coupling said outer catheter to said braided tube for axial movement.
Claim 10
Independent Claim
