Endoprosthesis assembly for percutaneous deployment and method of deploying same
First Claim
1. An endoprosthesis assembly for percutaneous deployment and implantation within a body passageway, comprising:
- a radially expandable cylindrical frame having first and second ends, said fame having a first unexpanded outer diameter and a second expanded outer diameter; and
a radially expandable elastomeric sleeve surrounding a length of said frame and having first and second ends, said sleeve having a first unexpanded inner diameter and a second expanded inner diameter;
wherein said second expanded inner diameter of said sleeve is not greater than said second expanded outer diameter of said frame;
wherein said sleeve, when expanded, has a sleeve modulus in a range from about 100 psi to about 6000 psi; and
wherein said second expanded inner diameter of said sleeve is in a range from about 60% to about 380% greater than said first unexpanded inner diameter of said sleeve.

Abstract
The present invention provides an endoprosthesis assembly having a reduced cross sectional profile for percutaneous deployment and implantation within a body passageway such as a blood vessel. The assembly comprises a radially expandable cylindrical frame having first and second ends, and a first unexpanded outer diameter and a second expanded outer diameter. The assembly further comprises a radially expandable elastomeric sleeve surrounding a length of the frame and having first and second ends and a first unexpanded inner diameter and a second expanded inner diameter. The inner diameter of the expanded sleeve is not greater than the outer diameter of the expanded frame. The second expanded inner diameter of the sleeve is in a range from about 60% to about 380% greater than the first unexpanded inner diameter of the sleeve. The assembly of the preferred embodiment is adapted to be deployed through an introducer smaller than 9 French and the sleeve is capable of expanding to an inner diameter of about 12 millimeters.

20. A method of percutaneously deploying an endoprosthesis assembly for implantation at a treatment site within a body passageway of a patient, comprising the steps of:
-
(a) forming said assembly by surrounding a length of an unexpanded cylindrical fame having a first unexpanded outer diameter with an elastomeric sleeve having a first unexpanded inner diameter; (b) inserting said assembly into said body passageway; (c) threading said assembly through said body passageway until said assembly reaches said treatment site; and (d) expanding said frame to a second expanded outer diameter such that said sleeve is expanded to a second expanded inner diameter not greater than said second expanded outer diameter of said frame and such that said sleeve is expanded to a second expanded outer diameter not less than an inner diameter of said body passageway at said treatment site, wherein said sleeve, when expanded, has a sleeve modulus in a range from about 100 psi to about 6000 psi and wherein said second expanded inner diameter of said sleeve is in a range from about 60% to about 380% greater than said first unexpanded inner diameter of said sleeve. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
