IMPLANTABLE MEDICAL DEVICE WITH CONSTRAINED EXPANSION
First Claim
1. A medical device for implantation in a body vessel, comprising:
- a support structure having a first, unexpanded configuration and a second, expanded configuration; and
a graft member connected to the support structure and comprising a valve portion and a constraining portion, the constraining portion sized to be drawn taught as the support structure expands from the first configuration to the second configuration and the valve portion adapted to permit fluid flow through said body vessel in a first direction and substantially prevent fluid flow through said body vessel in a second, opposite direction.

Abstract
Medical devices for implantation in a body vessel are provided. A medical device according to the invention comprises a support structure and one or more graft members comprising a valve portion and a constraining portion. The support structure has a first, unexpanded configuration and a second, expanded configuration. The constraining portion is adapted to substantially prevent the support structure from achieving the second, expanded configuration. The valve portion is adapted to permit fluid flow through a body vessel in a first direction and substantially prevent fluid flow through the vessel in a second, opposite direction.
