Abstract
Abstract The invention is directed to an expandable stent for implantation in a body lumen, such as an artery, and a method for making it from a single length of tubing. The stent consists of a plurality of radially expandable cylindrical elements generally aligned on a common axis and interconnected by one or more interconnective elements. The individual radially expandable cylindrical elements consist of ribbon-like material disposed in an undulating pattern. Portions of the expanded stent project outwardly into engagement with the vessel wall to more securely attach the stent.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
106 words
A method of implanting a stent in a body lumen, comprising the steps of: (a) providing a stent; (b) mounting the stent on a balloon of a balloon catheter; (c) partially inflating the balloon to secure the stent onto the balloon; (d) advancing the catheter, including the balloon and stent, through the body lumen; (e) positioning the balloon and stent at a desired location in the body lumen; (f) expanding the balloon, thereby deploying the stent at the desired location; (g) deflating the balloon; and (h) removing the catheter from the body lumen, whereby the stent remains deployed at the desired location in the body lumen.
Claim 2
Independent Claim
106 words
A method of implanting a stent in a body lumen, comprising the steps of: (a) providing a stent; (b) mounting the stent on a balloon of a balloon catheter; (c) partially inflating the balloon to secure the stent onto the balloon; (d) advancing the catheter, including the balloon and stent, through the body lumen; (e) positioning the balloon and stent at a desired location in the body lumen; (f) expanding the balloon, thereby deploying the stent at the desired location; (g) deflating the balloon; and (h) removing the catheter from the body lumen, whereby the stent remains deployed at the desired location in the body lumen.
Claim 3
Dependent Claim
20 words
The method of claim 1 , wherein step (a) includes forming the stent as a plurality of interconnected expandable elements.
Claim 4
Dependent Claim
26 words
The method of claim 1 , including, prior to step (f), the further step of: (i) mounting a generally tubular sleeve around the stent and balloon.
Claim 5
Dependent Claim
31 words
The method of claim 3 , including, prior to step (f) but after step (i), the further step of: (j) removing the generally tubular sleeve from around the stent and balloon.
Claim 6
Independent Claim
120 words
A method of implanting a stent in a body lumen, comprising the steps of: (a) providing a stent; (b) mounting the stent on an expandable member of a delivery catheter; (c) partially expanding the expandable member of the delivery catheter to secure the stent onto the expandable member; (d) advancing the catheter, including the expandable member and stent, through the body lumen; (e) positioning the expandable member and stent at a desired location in the body lumen; (f) expanding the expanding member, thereby deploying the stent at the desired location; (g) contracting the expandable member; and (h) removing the catheter and expandable member from the body lumen, whereby the stent remains deployed at the desired location in the body lumen.
Claim 7
Independent Claim
120 words
A method of implanting a stent in a body lumen, comprising the steps of: (a) providing a stent; (b) mounting the stent on an expandable member of a delivery catheter; (c) partially expanding the expandable member of the delivery catheter to secure the stent onto the expandable member; (d) advancing the catheter, including the expandable member and stent, through the body lumen; (e) positioning the expandable member and stent at a desired location in the body lumen; (f) expanding the expanding member, thereby deploying the stent at the desired location; (g) contracting the expandable member; and (h) removing the catheter and expandable member from the body lumen, whereby the stent remains deployed at the desired location in the body lumen.
Claim 8
Dependent Claim
20 words
The method of claim 5 , wherein step (a) includes forming the stent as a plurality of interconnected expandable elements.
Claim 9
Dependent Claim
16 words
The method of claim 5 , wherein step (a) includes forming the stent from stainless steel.
Claim 10
Dependent Claim
20 words
The method of claim 5 , wherein step (b) includes the step of crimping the stent onto the expandable member.
Claim 11
Dependent Claim
27 words
The method of claim 5 , including, prior to step (f), the further step of: (i) mounting a generally tubular sleeve around the stent and expandable member.
Claim 12
Dependent Claim
14 words
The method of claim 9 , wherein step (i) is performed after step (b).
Claim 13
Dependent Claim
31 words
The method of claim 9 , including, prior to step (f) but after step (i), the further step of: (j) removing the generally tubular sleeve from the stent and expandable member.
Claim 14
Dependent Claim
14 words
The method of claim 5 , wherein step (d) is performed after step (c).
Claim 15
Dependent Claim
14 words
The method of claim 1 , wherein step (d) is performed after step (c).
