Abstract
Abstract A delivery system for delivering an endoluminal implant to a distal deployment location inside a body lumen from a proximal access location outside the lumen. The system comprises the implant, a catheter, and a slidable sheath having an advanced position in which the sheath covers the implant and a retracted position in which the implant is exposed. The catheter comprises a stabilizer having a distal end adjacent the implant proximal end and/or a catheter tip attached to a central core slideably disposed relative to the implant and having a proximal end adjacent the implant distal end. The catheter tip proximal end and/or the stabilizer distal end comprises a docking section adapted to releasably engage a portion of the implant. Each docking section has an engagement geometry comprising a flared engagement surface that extends inside a short axial length of the implant or a pocket having a bottleneck geometry.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
158 words
A delivery system for delivering an endoluminal implant to a distal deployment location inside a body lumen from a proximal access location outside the body lumen, the delivery system comprising: the implant having a proximal end and a distal end; a catheter comprising, a catheter tip, the catheter tip having a proximal end located adjacent the implant distal end and attached to a central core slideably disposed relative to the implant; the catheter tip proximal end comprising a docking section adapted to releasably engage a portion of the implant, the docking section comprising a pocket adapted to releasably contain a limited length of one end of the compressed implant inserted therein, the pocket comprising an annular pocket having an inner wall located radially inward of the compressed implant and an outer wall located radially outward of the compressed implant, the inner wall and the outer wall both terminating at a substantially same axial location relative to the implant.
Claim 2
Dependent Claim
158 words
A delivery system for delivering an endoluminal implant to a distal deployment location inside a body lumen from a proximal access location outside the body lumen, the delivery system comprising: the implant having a proximal end and a distal end; a catheter comprising, a catheter tip, the catheter tip having a proximal end located adjacent the implant distal end and attached to a central core slideably disposed relative to the implant; the catheter tip proximal end comprising a docking section adapted to releasably engage a portion of the implant, the docking section comprising a pocket adapted to releasably contain a limited length of one end of the compressed implant inserted therein, the pocket comprising an annular pocket having an inner wall located radially inward of the compressed implant and an outer wall located radially outward of the compressed implant, the inner wall and the outer wall both terminating at a substantially same axial location relative to the implant.
Claim 3
Dependent Claim
17 words
The delivery system of claim 1 , wherein the docking section is integral to the catheter tip.
Claim 4
Dependent Claim
17 words
The delivery system of claim 1 , wherein the docking section is an attachment to the catheter.
Claim 5
Dependent Claim
58 words
The delivery system of claim 1 wherein the docking section comprises a set of fingers comprising an inner set of fingers that extend inside a short axial length of the stent, and an outer set of fingers that extend over a short axial length of the stent forming an annular region between inner and outer sets of fingers.
Claim 6
Dependent Claim
154 words
A delivery system for delivering an endoluminal implant to a distal deployment location inside a body lumen from a proximal access location outside the body lumen, the delivery system comprising: the implant having a proximal end and a distal end; a catheter comprising, a catheter tip, the catheter tip attached to a central core slideably disposed relative to the implant and having a proximal end located adjacent the implant distal end; the catheter tip proximal end comprising a docking section adapted to releasably engage a portion of the implant, the docking section comprising an engagement geometry for engaging the implant, and; a slidable sheath having an advanced position in which the sheath covers the implant and a retracted position in which the implant is exposed; the docking section engagement geometry comprising (a) a pocket having an outer wall located radially outward of the compressed implant and (b) a radial protrusion that engages the implant.
Claim 7
Dependent Claim
154 words
A delivery system for delivering an endoluminal implant to a distal deployment location inside a body lumen from a proximal access location outside the body lumen, the delivery system comprising: the implant having a proximal end and a distal end; a catheter comprising, a catheter tip, the catheter tip attached to a central core slideably disposed relative to the implant and having a proximal end located adjacent the implant distal end; the catheter tip proximal end comprising a docking section adapted to releasably engage a portion of the implant, the docking section comprising an engagement geometry for engaging the implant, and; a slidable sheath having an advanced position in which the sheath covers the implant and a retracted position in which the implant is exposed; the docking section engagement geometry comprising (a) a pocket having an outer wall located radially outward of the compressed implant and (b) a radial protrusion that engages the implant.
Claim 8
Dependent Claim
20 words
The delivery system of claim 5 , wherein the docking section radial protrusion protrudes inward from the pocket outer wall.
Claim 9
Dependent Claim
63 words
The delivery system of claim 6 , wherein the docking section pocket comprises a flared end rim radially biased outward relative to the compressed stent and adapted for the inward protrusion to releasably grip a limited length of the proximal end of the stent in pushing engagement therewith when the flared end rim is inwardly compressed by the sheath to a non-flared diameter.
