Abstract
Abstract A system/assembly for delivery and deployment of an inflation expandable stent within a vessel, comprising a catheter having proximal and distal ends; a stent, inflation expandable from a delivery diameter to a deployment diameter, such that the delivery diameter is reduced from the deployment diameter for conforming the stent to the catheter, such that the stent, in its delivery diameter, is coaxially mounted on the catheter near the catheter distal end; an expandable inflation member coaxially mounted on the catheter axially within the stent, for expansion of the stent from the delivery diameter to the deployment diameter upon application of fluid deployment pressure to the inflation member; and a securement component coaxially mounted on the catheter, axially within the expandable inflation members, the securement component designed and adapted to provide a securement pressure to the stent in the delivery diameter to maintain the stent in position on the catheter during delivery to the deployment site.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
267 words
A system/assembly for delivery and deployment of an inflation expandable stent within a vessel, comprising: a catheter having proximal and distal ends; a stent, inflation expandable from a delivery diameter to a deployment diameter, such that the delivery diameter is reduced from the deployment diameter for conforming the stent to the catheter, such that the stent, in its delivery diameter, is coaxially mounted on the catheter near the catheter distal end; an expandable inflation means coaxially mounted on the catheter within the stent, for expansion of the stent from the delivery diameter to the deployment diameter upon application of deployment pressure to the expandable inflation means; and a mounting and retaining means coaxially mounted on the catheter within the expandable inflation means, the mounting and retaining means designed and adapted to provide a securement for the stent in the delivery diameter to maintain the stent in position on the catheter during delivery to the deployment site, the catheter having a shaft and the expandable inflation means being positioned at a distal part of the shaft, the mounting and retaining means being positioned for receiving the stent on the expandable inflation means for radial expansion of the stent upon expansion of the expandable inflation means, the mounting and retaining means including at least one mounting body carried by the shaft inside the expandable inflation means whereby the diameter of the shaft and expandable inflation means are increased at the distal part for facilitating the mounting and retaining of the sent, the mounting body including at least one separation, whereby the flexibility of the body and catheter is increased.
Claim 2
Independent Claim
267 words
A system/assembly for delivery and deployment of an inflation expandable stent within a vessel, comprising: a catheter having proximal and distal ends; a stent, inflation expandable from a delivery diameter to a deployment diameter, such that the delivery diameter is reduced from the deployment diameter for conforming the stent to the catheter, such that the stent, in its delivery diameter, is coaxially mounted on the catheter near the catheter distal end; an expandable inflation means coaxially mounted on the catheter within the stent, for expansion of the stent from the delivery diameter to the deployment diameter upon application of deployment pressure to the expandable inflation means; and a mounting and retaining means coaxially mounted on the catheter within the expandable inflation means, the mounting and retaining means designed and adapted to provide a securement for the stent in the delivery diameter to maintain the stent in position on the catheter during delivery to the deployment site, the catheter having a shaft and the expandable inflation means being positioned at a distal part of the shaft, the mounting and retaining means being positioned for receiving the stent on the expandable inflation means for radial expansion of the stent upon expansion of the expandable inflation means, the mounting and retaining means including at least one mounting body carried by the shaft inside the expandable inflation means whereby the diameter of the shaft and expandable inflation means are increased at the distal part for facilitating the mounting and retaining of the sent, the mounting body including at least one separation, whereby the flexibility of the body and catheter is increased.
Claim 3
Dependent Claim
17 words
The system of claim 1 wherein the mounting body is substantially the same length as the stent.
Claim 4
Dependent Claim
43 words
