Abstract
Abstract An apparatus for ligating sectioned blood vessels comprising a cylindrical body adapted for removable attachment to a suction source and applied against the end of a sectioned vessel and the tissue zone there surrounding to effect simultaneously the elimination of blood and the formation within the cylindrical body of a tissue bud containing the end of the vessel. A ligature member is then applied 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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
126 words
An apparatus for ligating sectioned blood vessels comprising a cylindrical body including means for removably attaching the body to a suction source, said cylindrical body having an open end which can be placed against the end of a sectioned vessel and the tissue region therearound to form a tissue bud thereof within said body under the suction pressure from said suction source, means on said body for supporting a closure member adapted to ligate said vessel, said means supporting said closure member in surrounding relation to said bud, and actuator means operated externally of said body for applying said closure member around said bud in the course of application of suction pressure thereto to contract the tissue bud and close said end of the sectioned vessel.
Claim 2
Independent Claim
126 words
An apparatus for ligating sectioned blood vessels comprising a cylindrical body including means for removably attaching the body to a suction source, said cylindrical body having an open end which can be placed against the end of a sectioned vessel and the tissue region therearound to form a tissue bud thereof within said body under the suction pressure from said suction source, means on said body for supporting a closure member adapted to ligate said vessel, said means supporting said closure member in surrounding relation to said bud, and actuator means operated externally of said body for applying said closure member around said bud in the course of application of suction pressure thereto to contract the tissue bud and close said end of the sectioned vessel.
Claim 3
Dependent Claim
74 words
An apparatus as claimed in claim 1 wherein said closure member comprises a preformed loop of ligature thread arranged at said open end of the cylindrical body, said loop being held removably in place, said loop having free portions extending externally of said body and having remote ends, said actuator means comprising a control member connected to said remote ends of the free portions of the loop and supported for movement along said body.
Claim 4
Dependent Claim
47 words
An apparatus as claimed in claim 1 wherein said supporting means comprises a shoulder formed in said body at said open end, the preformed loop of ligature thread detachably resting in place on said shoulder with said thread being embedded substantially to its mid-thickness within said body.
Claim 5
Dependent Claim
22 words
An apparatus as claimed in claim 3 wherein the preformed loop of the ligature thread is held removably in place by adhesive.
Claim 6
Dependent Claim
40 words
An apparatus as claimed in claim 2 wherein said control member is separable from said body to enable separate removal of the body from the ligated vessel, the control member being independently separable from the ligature thread ligatiNg said vessel.
Claim 7
Dependent Claim
32 words
An apparatus as claimed in claim 1 wherein said means for supporting a closure member comprises means within said body for supporting a closure member in the form of a metal clip.
Claim 8
Dependent Claim
87 words
An apparatus as claimed in claim 6 wherein said body constitutes a magazine for a plurality of said metal clips arranged on e behind the other, the foremost clip being positioned against a stop provided at said open end of the body in which said tissue bud is formed, said actuator means comprising articulated jaws on said body for clamping the clip against the base of said bud, and resilient means for bringing succeeding clips into engagement with said stop after the first clip has been used.
