Abstract
Abstract A method and a device for joining luminal structures. The device is comprised of a bridge, typically cylindrical, having an interior dimension to receive two sets of curved needles and having a series of holes or channels at each end for passage of the needles through the body of the bridge. A plunger, typically activated by an elongated member, urges the needles, point first, through the channels. When the ends of the bridge are inserted into the luminal structures to be joined and the plunger is activated, the needles will move through the channels and through the luminal structure to be joined, allowing the surgeon to grasp the pointed ends of the needles and pull them through the channels and through the luminal structure. On the second ends of the needles are sutures which will ultimately be used to join the two luminal structures.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
149 words
A system for surgically joining at least two luminal structures, the system comprising: a bridge having walls defining an interior space, a first end and a second end, and a body, said body being between said first end and said second end, said bridge capable of being inserted, at least partially, into the luminal structures; a first needle having a pointed first end and a second end, said needle dimensioned to be fitted into the interior of said bridge; suture material for engaging the second end of said first needle; channel for guiding said first needle through said bridge into the luminal structures to be joined; wherein one end of said bridge is at least partially inserted into an end of one of the luminal structures to be joined for receipt of said first needle through said guiding means and through the walls of one of the luminal structures.
Claim 2
Independent Claim
149 words
A system for surgically joining at least two luminal structures, the system comprising: a bridge having walls defining an interior space, a first end and a second end, and a body, said body being between said first end and said second end, said bridge capable of being inserted, at least partially, into the luminal structures; a first needle having a pointed first end and a second end, said needle dimensioned to be fitted into the interior of said bridge; suture material for engaging the second end of said first needle; channel for guiding said first needle through said bridge into the luminal structures to be joined; wherein one end of said bridge is at least partially inserted into an end of one of the luminal structures to be joined for receipt of said first needle through said guiding means and through the walls of one of the luminal structures.
Claim 3
Dependent Claim
20 words
The system as set forth in claim 1 further including means for urging said first needle through said guide means.
Claim 4
Dependent Claim
39 words
The system as set forth in claim 1, wherein said channels include a first group of channels in the first end of said bridge and a correspondingly arranged second group of channels in the second end of said bridge.
Claim 5
Dependent Claim
38 words
The system as set forth in claim 1 further including a second needle, said second needle having a pointed first end and a second end, said second needle capable of being fitted into the interior of said bridge.
Claim 6
Dependent Claim
86 words
The system as set forth in claim 4, wherein said suture material includes a first section having a first end and a second end, the first section for attaching the first end thereof to the second end of said first needle and the second end thereof to the second end of the second needle, said first and said second needle now defining a first joined needle pair, said urging means further capable of urging said second needle through the channels in the walls of said bridge.
Claim 7
Dependent Claim
49 words
The system as set forth in claim 5 further including a multiplicity of needles and a multiplicity of suture material sections, the needles of the multiplicity of needles and the sections of the multiplicity of needle sections forming a multiplicity of joined needle pairs as the first needle pair.
Claim 8
Dependent Claim
36 words
The system as set forth in claim 6, wherein said urging means is capable of urging simultaneously the first needles of said multiplicity of joined needle pairs through the channels of the walls of the bridge.
Claim 9
Dependent Claim
50 words
The system as set forth in claim 7, wherein said multiplicity of joined needle pairs includes a first set comprising the first needles of the pairs and a second set, the second set comprising the second needles of the pairs, the two sets located at opposed ends of the bridge.
Claim 10
Dependent Claim
19 words
The system as set forth in claim 8, wherein an end of said bridge is either tapered or straight.
Claim 11
Dependent Claim
34 words
The system as set forth in claim 9, wherein said bridge has an opening in the body thereof and wherein said urging means is operable on said multiplicity of pairs through the body opening.
Claim 12
Dependent Claim
17 words
The system as set forth in claim 10, wherein the body of said bridge has indicia thereon.
Claim 13
Dependent Claim
23 words
The system as set forth in claim 10, wherein the sections of said suture material include means to discriminate one from the other.
Claim 14
Dependent Claim
156 words
The system as set forth in claim 10, wherein said bridge is substantially hollow and said urging means includes a pair of plungers shaped to fit flush against the inner surface of the walls of said bridge, the first of the pair of plungers for engaging the first set of the multiplicity of joined needle pairs, the second plunger of the pair of plungers for engaging the second set of the multiplicity of joined needle pairs, said urging means further including an elongated member having a first end and a second end, the first end for inserting through the body opening of said bridge and the second end for grasping by the user, wherein an axial force, applied to the elongated member, will urge either of the pair of plungers against the needles of the joined needle set to urge the needles through the walls of said bridge and through the walls of the luminal structure.
Claim 15
Dependent Claim
31 words
The system as set forth in claim 13, wherein said needles of said multiplicity of joined needle pairs are curved, the curve transcribing an arc of between 10 and 270 degrees.
Claim 16
Dependent Claim
33 words
The system as set forth in claim 13, wherein at least some of said needles are different lengths than other of said needles and wherein said plungers have at least one beveled surface.
Claim 17
Dependent Claim
18 words
The system as set forth in claim 1, wherein said bridge has a body defining multiple, non-linear axes.
Claim 18
Dependent Claim
18 words
The system as set forth in claim 8, wherein an end of said bridge is open or closed.
