Abstract
An embodiment of the invention relates to an apparatus for supporting first and second blood vessels connected by an anastomosis at a fistula, the apparatus comprising: a coupler that seats on and couples to the first blood vessel; and a sleeve connected to the coupler that ensheathes a portion of the second blood vessel in the vicinity of the fistula.

Apparatus for configuring first and second blood vessels connected by an anastomosis at a fistula, the apparatus comprising:
- a coupler comprising:
- a mount having a saddle-like shape that seats on and couples to the first blood vessel;
- an adapter having a substantially cylindrical shape that extends from the mount in the vicinity of the fistula;
- and
- a brace extending from a side of the mount that can be closed to prevent the coupler from lifting off from the first blood vessel;
- and
- a sleeve connected to the adapter that ensheathes and holds a portion of the second blood vessel in the vicinity of the fistula so that the first and second blood vessels are joined at an acute angle.
Apparatus for supporting first and second blood vessels connected by an anastomosis at a fistula, the apparatus comprising:
- a coupler that seats on and couples to the first blood vessel;
- and
- a sleeve connected to the coupler that ensheathes a portion of the second blood vessel in the vicinity of the fistula and has a cross section that increases as a function of distance from the coupler along the sleeve for at least a first portion of the sleeve length.
A method of configuring blood vessels at an anastomosis, the method comprising:
- making an incision having edges in a first blood vessel;
- transecting a second blood vessel to provide a blood vessel segment having an open end;
- ensheathing the segment in a sleeve so that the open end protrudes from the sleeve;
- suturing the open end to the edges of the incision to form a fistula;
- sliding the sleeve along the second blood vessel to position the sleeve at the anastomosis;
- and
- coupling the sleeve to the first blood vessel so that the sleeve configures a portion of the second blood vessel that extends from the fistula.
