Catheter for stent delivery having expanded inner member
First Claim
1. An inner member for use within a stent delivery system, wherein the stent delivery system has a stent and a balloon disposed within the stent, the balloon configured to be mounted about the inner member in a collapsed state, the inner member comprising:
- a proximal and a distal section, each having a first outer diameter, the proximal and distal sections having a first and a second lumen therethrough, respectively; and
an intermediate section having a third lumen therethrough in communication with the first and second lumens and having a second outer diameter larger than the first outer diameter for exerting a retaining force on the stent.

Abstract
An inner member for use within a stent delivery system is provided, wherein the stent delivery system has a stent and a balloon disposed within the stent, the balloon configured to be mounted about the inner member in a collapsed state. The inner member comprises a proximal section, a distal section, and an intermediate section. The proximal and distal sections each have a first outer diameter. The proximal and distal sections have a first and a second lumen therethrough, respectively. The intermediate section having a third lumen therethrough in communication with the first and second lumens and has a second outer diameter larger than the first outer diameter for exerting a retaining force on the stent.

13. An inner member for use within a stent delivery system, wherein the stent delivery system has a stent and a balloon disposed within the stent, the ballon configured to be mounted about the inner member in a collapsed state, the inner member comprising:
-
a proximal and a distal section, each having a first outer diameter and a first inner diameter, the proximal and distal sections having a first and a second lumen therethrough, respectively; and
an intermediate section having a third lumen therethrough in communication with and bondedly coupled to the first and second lumens, the intermediate section having a second outer diameter larger than the first outer diameter for exerting a retaining force on the stent and a second inner diameter larger than the first inner diameter, wherein proximal and distal sections comprise a flexible material and the intermediate section comprises material capable of being formed into a desired shape and size and heat treated to maintain said desired shape and size. - View Dependent Claims (14, 15, 16)

17. An inner member for use within a stent delivery system, wherein the stent delivery system has a stent and a balloon disposed within the stent, the balloon configured to be mounted about the inner member in a collapsed state and having a length in the collapsed state, the inner member comprising:
-
a proximal and a distal section, each having a first outer diameter and a first inner diameter, the proximal and distal sections having a first and a second lumen therethrough, respectively; and
an intermediate section having a third lumen therethrough in communication with the first and second lumens, a second outer diameter larger than the first outer diameter for exerting a retaining force on the stent, a second inner diameter that is substantially equal to the first inner diameter, and a length that is substantially equal to the length of the balloon in the collapsed state, wherein the proximal and distal sections comprise a flexible material and the intermediate section comprises material capable of being formed into a desired shape and size and heat treated to maintain said desired shape and size. - View Dependent Claims (18, 19, 20, 21, 22, 23)
