Abstract A process for ligating sectioned blood vessels comprising applying a cylindrical body adapted for removable attachment to a suction source against the end of a sectioned vessel and the tissue zone theresurrounding to effect simultaneously the elimination of blood and the formation within the cylindrical body of a tissue bud containing the end of the vessel, and thereafter applying a ligature member to the tissue bud at the base thereof, while still applying the suction force, to close the vessel end. The closure member can be a loop of ligature thread which is supported at the open end of the cylindrical body and which is applied to the tissue bud by acting on an external actuator. The closure member can also be a metal clip which is initially supported within the cylindrical body and is deformed and clamped at the base of the bud by acting on an external actuator.
A process for ligating sectioned blood vessels comprising applying suction force to the end of a sectioned vessel, as well as the tissue zone surrounding it to effect simultaneously the elimination of blood and the formation of a tissue bud containing the end of the vessel, and contracting the tissue bud at the base thereof, while still applying the suction to close said vessel end.

A process for ligating sectioned blood vessels comprising applying suction force to the end of a sectioned vessel, as well as the tissue zone surrounding it to effect simultaneously the elimination of blood and the formation of a tissue bud containing the end of the vessel, and contracting the tissue bud at the base thereof, while still applying the suction to close said vessel end.
Claim 3
Dependent Claim
23 words
A process as claimed in claim 1 wherein said contraction of the tissue bud is effected from a location remote from said bud.
Claim 4
Dependent Claim
42 words
A process as claimed in claim 1 wherein the tissue bud is formed within a channel which is subjected to the suction force, and the tissue bud is contracted by applying a closure member thereto when the bud is in said channel.
