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.
