Abstract
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.

Dependent Claim
129 words
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 valve portion adapted to permit fluid flow through said vessel in a first direction and substantially prevent fluid flow through said vessel in a second, opposite direction, and the constraining portion comprising a gathered portion of the graft member and adapted to substantially prevent the support structure from achieving the second, expanded configuration; wherein the gathered portion defines a passageway adapted to permit a controlled amount of fluid flow through said body vessel in the second, opposite direction; and further comprising a cannula disposed in the passageway.
Claim 10
Dependent Claim
51 words
The medical device of claim 7 , wherein the cannula comprises a distal end disposed near the valve portion of the graft member and a proximal end disposed near the constraining portion of the graft member, and wherein the proximal end defines an opening angulated with respect to the graft member.
Claim 11
Dependent Claim
132 words
A medical device for implantation in a body vessel, comprising: a support structure; and first and second graft members connected to the support structure, each of the graft members comprising a valve portion and a constraining portion, the valve portions being disposed substantially opposite one another and adapted to cooperatively permit fluid flow through said vessel in a first direction and substantially prevent fluid flow through said vessel in a second, opposite direction; wherein at least one of the constraining portions comprises a gathered portion of one of the first and second graft members, the gathered portion including first and second non-contiguous regions of the graft member held adjacent one another by a connecting mechanism; wherein the constraining portions cooperate to substantially prevent the support structure from achieving the second, expanded configuration.
