BRANCHED VESSEL PROSTHESIS
First Claim
1. A branched vessel prosthesis comprising:
- two longitudinally spaced primary hoop members and at least one primary longitudinal strut coupling the two primary hoop members to define a primary lumen through the primary hoop members about a longitudinal axis, the primary hoop members being movable between a radially compressed configuration and a radially expanded configuration, anda branch hoop member and at least one flexible member coupling the branch hoop member with at least one of the primary hoop members, the branch hoop member being movable between a first position and a second position, where in the first position the branch hoop member is disposed within the primary lumen and between the primary hoop members in the radially compressed configuration, where in the second position the branch hoop member is disposed outside the primary lumen when the primary hoop members are in the radially expanded configuration, the branch hoop member in the second position defining a branch lumen about a branch axis in communication with the primary lumen.

Abstract
The present disclosure describes an implantable branched vessel prosthesis, such as a prosthetic valve, having both a radially expandable annular portion and a laterally extendable branch portion. Methods of delivering the branched vessel prosthesis to a branched body vessel are also provided, as well as delivery systems comprising the branched vessel prosthesis. The branched vessel prostheses are useful, for example, as implantable prosthetic venous valves for treating venous valve insufficiency. The delivery system is configured to deploy independently both the annular portion within a primary vessel and the branch portion within a branch vessel with only one delivery system.

11. A branched vessel prosthesis delivery system comprising:
-
a delivery catheter extending from a proximal end to a distal end about a longitudinal axis, the delivery catheter including an outer sheath enclosing an inner shaft portion, the outer sheath being translatable along the longitudinal axis relative to the inner shaft; and a branched vessel prosthesis having a support frame comprising two longitudinally spaced primary hoop members and at least one primary longitudinal strut coupling the two primary hoop members to define a primary lumen through the primary hoop members, the primary hoop members being movable between a radially compressed configuration and a radially expanded configuration, and a branch hoop member and at least one flexible member coupling the branch hoop member with at least one of the primary hoop members, the branch hoop member being movable between a first position and a second position, where in the first position the branch hoop member is within the primary lumen and between the primary hoop members in the radially compressed configuration, where in the second position the branch hoop member is outside the primary lumen when the primary hoop members are in the radially expanded configuration, the branch hoop member in the second position defining a branch lumen in communication with the primary lumen, wherein the outer sheath and the inner shaft portion are configured and oriented such that a retaining region is formed to receive the branched vessel prosthesis with the primary hoop members in the radially compressed configuration and the branch hoop member in the first position. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 20)

19. A method of delivering a branched vessel prosthesis to a point of treatment at a branched vessel site formed from a first body vessel and a second body vessel in fluid communication with the first body vessel, comprising the steps of:
-
inserting a branched vessel prosthesis in a compressed configuration into said body vessel, the branched vessel prosthesis having a support frame comprising two primary hoop members and at least one primary longitudinal strut coupling the two primary hoop members to define a primary lumen through the primary hoop members, the primary hoop members being in a radially compressed configuration, and a branch hoop member and at least one flexible strut coupling the branch hoop member with at least one of the primary hoop members, the branch hoop member being in a first position where the branch hoop member is within the primary lumen and between the primary hoop members in the radially compressed configuration, translating the branched vessel prosthesis to said point of treatment at said branched vessel site; radially expanding the primary hoop members from the radially compressed configuration to a radially expanded configuration to implant the primary hoop members within said first body vessel; and extending the branch hoop member radially outward from the first position to a second position so that the branch hoop member is positioned within said second body vessel, where in the second position the branch hoop member is outside the primary lumen when the primary hoop members are in the radially expanded configuration and defines a branch lumen in communication with the primary lumen, such that the branched vessel prosthesis is deployed at said point of treatment at said branched vessel site.
