Abstract
Abstract Disclosed herein is a device for joining together separated arteries, lumen or the like. The device includes an innertube of substantially cylindrical configuration having end portions which taper somewhat and terminate at opposed extremities in a fine feathered end. Attached to the center cylindrical portion, is a sleeve grip mechanism which extends over the tapered portions as well so that when an artery is slidably disposed over the tapered portions of the innertube, the sleeve grip can wrap around the central cylindrical portion and the tapering portion, and opposed ends of the sleeve grip can be fastened together to securely affix the dissociated artery to the central cylindrical portion thereby repairing the artery and allowing the flow of blood to recommence therethrough.
