Abstract
Abstract A tubular surgical implant for joining to a wall of a vessel or hollow organ is disclosed such that the implant opens into the interior of the vessel or organ. The implant has an open ended tube, a deformable flange at one end of the tube, a plurality of spikes extending from the flange, alongside and generally parallel to the tube, and a locking ring arranged to slide axially on the tube, the locking ring incorporating a plurality of holes aligned with and adapted to received the spikes.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
135 words
A tubular surgical implant adapted to be joined to a wall of a vessel or hollow organ such that the implant opens into the interior of the vessel or organ, said implant comprising: an open-ended tube having a distal end and a proximal end, a deformable flange formed at the distal end of the tube for insertion through an opening in the wall of the vessel or hollow organ, a plurality of spikes extending from the flange toward the proximal end of the tube, alongside and generally parallel to the tube, and a locking ring arranged to slide axially on the tube in a direction from the proximal end of the tube toward the distal end of the tube, the locking ring incorporating a plurality of holes aligned with and adapted to receive the spikes.
Claim 2
Dependent Claim
135 words
A tubular surgical implant adapted to be joined to a wall of a vessel or hollow organ such that the implant opens into the interior of the vessel or organ, said implant comprising: an open-ended tube having a distal end and a proximal end, a deformable flange formed at the distal end of the tube for insertion through an opening in the wall of the vessel or hollow organ, a plurality of spikes extending from the flange toward the proximal end of the tube, alongside and generally parallel to the tube, and a locking ring arranged to slide axially on the tube in a direction from the proximal end of the tube toward the distal end of the tube, the locking ring incorporating a plurality of holes aligned with and adapted to receive the spikes.
Claim 3
Dependent Claim
27 words
A tubular surgical implant as claimed in claim 1 wherein the locking ring is keyed to the tube, preventing rotation of the ring relative to the tube.
Claim 4
Dependent Claim
42 words
A tubular surgical implant as claimed in claim 1 wherein the spikes and the holes in the locking ring are provided with a locking mechanism arranged to retain the spikes within the holes when the locking ring is engaged with the spikes.
Claim 5
Dependent Claim
43 words
A tubular surgical implant as claimed in claim 1 wherein the flange is deformable relative to the tube such that the flange may be deformed to lie against the tube for insertion into an opening in the wall of the vessel or organ.
Claim 6
Dependent Claim
47 words
A tubular surgical implant as claimed in claim 1 wherein the flange is deformable across one or more hinge lined in the flange, allowing parts of the flange to bend back against the tube for insertion into an opening in the wall of the vessel or organ.
Claim 7
Dependent Claim
36 words
A tubular surgical implant as claimed in claim 1 wherein the implant is adapted to connect two vessels or hollow organs and is provided with a flange and locking ring at both ends of the tube.
Claim 8
Dependent Claim
28 words
A tubular surgical implant as claimed in claim 1 wherein the tube and the flange are made of a plastics mesh which allows for incorporation of human tissue.
Claim 9
Independent Claim
189 words
A method of connecting first and second vessels, or first and second hollow organs, or a first vessel and a second hollow organ, by way of a surgical implant, the method comprising the steps of: providing a tubular surgical implant adapted to be joined to a tissue wall of a vessel or organ such that the implant opens into the interior of the vessel or organ, the implant comprising an open-ended tube, a deformable flange at one end of the tube, a plurality of spikes extending from the flange, alongside and generally parallel to the tube, and a locking ring arranged to slide axially on the tube, and the locking ring incorporating a plurality of holes aligned with and adapted to receive the spikes; cutting an opening in the tissue wall of the first vessel or first organ; inserting the end of the tube into the opening with the flange deformed; allowing or causing the flange to open behind the tissue wall; engaging the spikes through the tissue wall; and sliding the locking ring on the tube until the spikes are engaged with the holes in the locking ring.
Claim 10
Independent Claim
189 words
A method of connecting first and second vessels, or first and second hollow organs, or a first vessel and a second hollow organ, by way of a surgical implant, the method comprising the steps of: providing a tubular surgical implant adapted to be joined to a tissue wall of a vessel or organ such that the implant opens into the interior of the vessel or organ, the implant comprising an open-ended tube, a deformable flange at one end of the tube, a plurality of spikes extending from the flange, alongside and generally parallel to the tube, and a locking ring arranged to slide axially on the tube, and the locking ring incorporating a plurality of holes aligned with and adapted to receive the spikes; cutting an opening in the tissue wall of the first vessel or first organ; inserting the end of the tube into the opening with the flange deformed; allowing or causing the flange to open behind the tissue wall; engaging the spikes through the tissue wall; and sliding the locking ring on the tube until the spikes are engaged with the holes in the locking ring.
Claim 11
Dependent Claim
60 words
A method as claimed in claim 8 wherein the area of the first vessel or the first organ surrounding the opening is isolated from the remainder of the first vessel or the first organ by way of a clamp before making the opening, in a manner allowing fluid to continue to flow through the remainder of the vessel or organ.
Claim 12
Dependent Claim
31 words
A method as claimed in claim 8 wherein the first vessel or the first organ comprises an aorta and the second vessel or the second organ comprises a distal coronary artery.
