An external vascular support for shaping a vein-artery junction between an artery and a vein anastomosed to the artery, the support comprising: an arterial portion that is shaped to be in apposition with an exterior wall of the artery when the artery is accommodated within a lumen of the arterial portion, and a venous portion that is shaped to be in apposition with an exterior wall of the vein when the vein is accommodated within a lumen of the venous portion, wherein the arterial and venous portions are physically connected at an acute angle, and the corner of the acute angle is shaped as a rounding having a radius of curvature in the range of 0.25 mm to 4 mm.

Vessel shaping devices and methods

An embodiment of the invention relates to a method of configuring blood vessels at an anastomosis, the method comprising: ensheathing a segment of a transected first blood vessel in a lumen of a sleeve so that an open end of the segment protrudes from a sleeve end; suturing edges of an incision made in a second blood vessel to the open end of the first blood vessel to create an anastomosis; and sliding the sleeve along the first blood vessel to position the sleeve at the anastomosis.

Method for configuring an arteriovenous fistula

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 an arteriovenous fistula

Disclosed is a medical device for shaping a vessel accommodated therein in a predetermined form, wherein said vessel includes a vein and an artery which are connected at a artifactual vascular junction thereof. The device includes an external vascular support () having at least one vascular support wall for accommodating an exterior vessel wall of a vessel therein when implanted. The support includes an arterial portion () for apposition with said artery when accommodated therein, and/or a venous portion () for apposition with said vein when accommodated therein. The venous portion () and/or said arterial portion () are shaped at a junction thereof to provide a vessel rounding to at least a portion of said vessel junction when in apposition with the latter upon implantation of said device for said vessel shaping. Corresponding methods are also disclosed. Thus dysfunction or failure of a vessel of the artifactual vascular junction may be reduced, minimized, or eliminated.
