Abstract
A medical device with an expandable element and expandable tubular sleeve surrounding at least a portion of the expandable element which influences the rate, shape and/or force required to expand the expandable element and methods for use in a body lumen are provided.
Claims37
1-27. (canceled)
A medical device, comprising:
- an elongated tubular body having proximal and distal ends;
- an expandable element at the distal end of the elongated tubular body;
- an expandable tubular sleeve including a first portion having a first radial strength and a second portion having a second radial strength that differs from the first radial strength, wherein the expandable element has a sequence of expansion dictated by the first and second radial strengths of the expandable tubular sleeve.
A medical device comprising:
- an elongated tubular body having proximal and distal ends;
- an expandable element at the distal end of the elongated tubular body;
- an expandable tubular sleeve including a first portion having a first compression ratio and a second region having a second compression ratio that differs from the first compression ratio, wherein the expandable element has a sequence of expansion dictated by the first and second compression ratios of the expandable tubular sleeve.
A medical device, comprising:
- an elongated tubular body having proximal and distal ends;
- an expandable element at the distal end of the elongated tubular body;
- an expandable tubular sleeve comprising at least two portions with differing radial strengths,
- wherein the medical device is withdrawn from a body lumen after expansion of the expandable element.

A method of treating a site on a body lumen using a medical device, comprising:
- providing a medical device comprising:
- an elongated tubular body having proximal and distal ends;
- an expandable element at the distal end of the elongated tubular body;
- and
- an expandable tubular sleeve includes a first portion having a first radial strength and a second portion having a second radial strength that differs from the first radial strength;
- positioning within a body lumen the medical device so that the expandable element in folded form is adjacent to a treatment site;
- expanding the expandable element at a pressure sufficient to expand the expandable element at the first portion of the expandable tubular sleeve;
- and
- expanding the expandable element at an increased pressure to expand the expandable element at the second portion of expandable tubular sleeve.
