First Claim
1. A coupler configured to connect a first tubular vessel to an aperture in a second tubular vessel, the coupler comprising:
- one or more radially extending members;
a substantially nonmetallic tubular member, the tubular member comprising an outer wall, an inner wall defining a lumen having an open distal end and an open proximal end, and a circumferential ridge encircling the outer wall, a distal portion of the radially extending members extending from the distal end of the tubular member and a proximal portion of the radially extending members being fixed within the tubular member; and
at least one securing member mounted to the distal end of the tubular member, the securing member comprising a first segment positioned adjacent to the inner wall, a second segment positioned against the outer wall, and a third segment connecting the first segment and the second segment.

Abstract
A coupler is configured to connect a first tubular vessel to an aperture in a second tubular vessel. The coupler includes one or more radially extending members and a substantially nonmetallic tubular member. The substantially nonmetallic tubular member include an outer wall, an inner wall defining a lumen having an open distal end and an open proximal end, and a circumferential ridge encircling the outer wall, the radially extending members extending from the distal end of the tubular member. A method of fabricating a coupler the method including fabricating radially extending members; placing the radially extending members within a mold; injecting a material into the mold; allowing the material to cure to form the coupler; and removing the coupler from the mold. The coupler includes a tubular member having an outer wall, an inner wall defining a lumen having an open distal end and an open proximal end, and a circumferential ridge encircling the outer wall. The radially extending members extend from the distal end of the tubular member.

11. A method of deploying a coupler, the coupler comprising one or more radially extending members, a substantially nonmetallic tubular member and at least one securing member, the tubular member comprising an outer wall, an inner wall defining a lumen having an open distal end and an open proximal end, and a circumferential ridge encircling at least a portion of the outer wall, a distal portion of the radially extending members extending from the distal end of the tubular member and a proximal portion of the radially extending members being fixed within the tubular member, and the at least one securing member being mounted to the distal end of the tubular member, the securing member comprising a first segment positioned adjacent to the inner wall, a second segment positioned against the outer wall, and a third segment connecting the first segment and the second segment, the method comprising:
-
forming an opening in a wall of a tubular vessel; deflecting the radially extending members into a longitudinally extending configuration; inserting the extending members at least partially into the opening; and releasing the extending members such that the extending members return to the radially extending configuration from the longitudinally extending configuration, whereby the wall of the tubular vessel is compressed between the radially extending members and the circumferential ridge. - View Dependent Claims (12, 13, 14)
