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.
