Abstract
Abstract An anastomotic device and method for receiving the free ends of anatomic tubular structures to be anastomosed, the device having a pair of ring members for securement to the free end of each of the tubular members to be anastomosed and the ring members having annular connecting means which mate with each other to connect the ring members. Novel securement means are associated with the annular connecting means to enable the securement of the ring members in a fixed relationship at a predetermined distance from each other. Means are provided to connect each tubular member free end over a ring member so that the free ends are positioned contiguous to each other around the connecting means to enable the ends to grow together and approximate the outer surface of the tubular member.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
153 words
An anastomosis device for use in the surgical joining of the free ends of two tubular members to be anastomosed, said device comprising: a pair of ring members for securement to the free end of each of the tubular members to be anastomosed, each of said ring members having an inner and outer surface; annular connecting means joined to each of said ring members cooperatively mating with each other to connect said ring members; means associated with said annular connecting means enabling the securement of said ring members in a fixed relationship at a predetermined distance each from the other; and means connecting each-tubular member free end over a ring member and to said connecting means whereby said tubular member free ends are positioned contiguous to each other over said ring members and around said connecting means to enable the ends to grow together and approximate the outer surface of the tubular member.
Claim 2
Dependent Claim
153 words
An anastomosis device for use in the surgical joining of the free ends of two tubular members to be anastomosed, said device comprising: a pair of ring members for securement to the free end of each of the tubular members to be anastomosed, each of said ring members having an inner and outer surface; annular connecting means joined to each of said ring members cooperatively mating with each other to connect said ring members; means associated with said annular connecting means enabling the securement of said ring members in a fixed relationship at a predetermined distance each from the other; and means connecting each-tubular member free end over a ring member and to said connecting means whereby said tubular member free ends are positioned contiguous to each other over said ring members and around said connecting means to enable the ends to grow together and approximate the outer surface of the tubular member.
Claim 3
Dependent Claim
47 words
The device as claimed in claim 1 wherein said annular connecting means includes at least two mating prongs joining said ring members and extending therefrom substantially parallel to the centerline of said ring members, said mating groups, cooperatively connecting with each-other to form an annular coupling tube.
Claim 4
Dependent Claim
71 words
The device as claimed in claim 2 wherein said securement enabling means includes a locking notch and an engaging slot carried by each of said mating prongs positioned to mate cooperatively with each other to secure said prongs and ring members in a preselected relationship with each other and thereby retain said ring members at a preselected distance from each other to accommodate the free ends of the two tubular members.
Claim 5
Dependent Claim
53 words
The device as claimed in claim 3 wherein said connecting means includes a purse string suture extending around each-tubular member free end pulling said free end in close engagement with said annular coupling tube and contiguous to the other tubular member free end -thereby enabling the tubular member free ends to grow together.
Claim 6
Dependent Claim
54 words
The device as claimed in claim 1 wherein said connecting means includes a purse string suture extending around each. tubular member free end pulling said free end in close engagement with said annular connecting means and contiguous to the other tubular member free end thereby enabling the tubular member free end to grow together.
Claim 7
Dependent Claim
30 words
The device as claimed in claim 1 wherein said ring members, said annular coupling tube, said securement enabling means, and said free end connecting means are formed of disintegratable material.
Claim 8
Dependent Claim
25 words
The device as claimed in claim 4 wherein said locking notches are engageable to position said ring members a preselected distance each from the other.
Claim 9
Dependent Claim
50 words
The device as claimed in claim 4 wherein each of said mating prongs contains a locking notch and an engaging slot, said engaging edges and said receiving slots cooperatively mating to retain said ring members in a fixed relationship each with the other when said annular coupling tube is formed.
Claim 10
Dependent Claim
25 words
The device as claimed in claim 8 wherein said ring members, said annular coupling tube, and said purse string sutures are formed of disintegratable material.
Claim 11
Dependent Claim
25 words
. The device as claimed in claim 9 wherein said ring members, said annular coupling tube, said purse string sutures are formed in integratable material.
Claim 12
Dependent Claim
35 words
The devices claimed in claim 1 wherein said annular connecting means includes pairs of cooperatively positioned legs and notch―receiving recesses depending from said ring members connecting with each other to form an annular coupling tube.
Claim 13
Dependent Claim
72 words
The devices claimed in claim 11 wherein each of said ring members has two oppositely positioned depending members affixed thereto; each of said depending legs has one or more engaging notches selectively positioned thereon; and each of said depending legs has a notch-receiving recess therein whereby said oppositely positioned depending legs and members cooperatively engage with each other to fixedly secure said ring members in a predetermined relationship each with the other
