1. A catheter assembly for deploying an endoluminal sleeve, the catheter assembly comprising:
- a balloon catheter having a distal portion and a proximal portion;
a balloon disposed at the distal portion of the balloon catheter, the balloon expandable from a deflated configuration to an expanded configuration;
an endoluminal sleeve disposed about the distal portion of the balloon catheter, the endoluminal sleeve being rolled longitudinally and having a rolled portion and an unrolled portion disposed about the balloon, the expanded configuration of the balloon expanding the unrolled portion of the balloon while leaving the rolled portion unexpanded; and
a thread rolled within the rolled portion of the endoluminal sleeve and extending from within the rolled portion.

Abstract
A device and method for deploying an endoluminal sleeve is disclosed. The endoluminal sleeve has a proximal end that is rolled with a thread. The distal end is disposed about a balloon and can be expanded to contact the lumen wall. An adhesive holds the sleeve in place and the endoluminal sleeve is unrolled. The balloon is deflated and moved to a second location. The balloon is then inflated again expanding the endoluminal sleeve proximate the second location.

7. A method for delivering an endoluminal sleeve, the method comprising:
-
introducing a catheter assembly into a body lumen, the catheter assembly comprising a balloon catheter having a distal portion with a balloon and a proximal portion, a sleeve disposed about the distal portion of the balloon catheter, the sleeve being rolled longitudinally and having a rolled portion and an unrolled portion disposed about the balloon, and a thread rolled within the rolled portion of the sleeve and extending from the rolled portion to the proximal portion of the balloon catheter; positioning the catheter assembly proximate a first location within the body lumen; inflating the balloon and expanding the unrolled portion of the sleeve to contact a wall of the body lumen at the first location while leaved the rolled portion unexpanded; adhering a first expanded portion of the sleeve to the wall of the body lumen at the first location; tensioning the thread to unroll a portion of the rolled portion of the sleeve; deflating the balloon subsequent to adhering the first expanded portion of the sleeve to the wall of the body lumen at the first location; moving the catheter to a second location within the body lumen proximate the first expanded portion of the sleeve; inflating the balloon and expanding a second portion of the sleeve to contact the wall of the body lumen at the second location; and adhering the second portion of the sleeve to the wall of the body lumen at the second location. - View Dependent Claims (8, 9, 10, 11, 12)
