Abstract

An apparatus for placing multiple sutures during anastomosis of physiological vessels includes a crown portion having a plurality of strands connected together by one or more circular bands. The strands each form a point at one end with a curved hook at the same end. The curved hook acts as a suture to retain one or more of the vessels. An alternative embodiment includes a plurality of strands, or wires, that are inserted through one or more vessels to simultaneously place multiple sutures. The present invention also comprises a method for placing a plurality of sutures simultaneously with an apparatus.

Claims

1. An apparatus for placing multiple sutures during anastomosis of physiological vessels, said apparatus comprising:

a crown comprising;

a plurality of strands, each strand of said plurality of strands having a first end and a second end, said strand first ends defining a first portion of said crown and said strand second ends defining a second portion of said crown;

at least one circular band joining together said plurality of strands adjacent said first ends of said strands;

each said strand forming a point at said second end thereof; and

each said strand forming a hook adjacent said second end thereof for attachment to at least one physiological vessel;

means for retaining each said hook in a first position for insertion of said second portion of said crown into physiological vessel; and

means for deploying each said hook from said first position to a second position for securing each said hook to the physiological vessel;

wherein said retaining means comprises a retaining ring, and said deploying means comprises removability of said retaining ring.

2. The apparatus of claim 1 wherein said removability of said retaining ring comprises severability by cutting said retaining ring.

3. A method for placing multiple sutures during anastomosis of physiological vessels, said method comprising:

providing a crown comprising;

a plurality of strands, each strand of said plurality of strands having a first end and a second end,

at least one circular band joining together said plurality of strands adjacent said first ends of said strands; and

each said strand forming a hook adjacent said second end of said strand with a point at said second end of said strand;

attaching a first physiological vessel to said crown by placing said first vessel within said crown and everting one end of said first vessel over said hooks; and

attaching a second physiological vessel to said crown such that said first physiological vessel and said second physiological vessel are substantially joined to one another.

4. A crown for surgical formation of an anastomosis, the crown comprising:

an end ring;

a plurality of strands fixed to an inside surface of said end ring proximate a first end of said strands, and spaced from an outside surface of said end ring, and extending normal to said end ring; and

each of said strands having a curved second end portion providing a distal end extending outwardly, the distal end being pointed;

wherein said strands are of substantially equal length and the pointed ends are disposed in a circle disposed concentrically outwardly from said end ring.

5. The crown in accordance with claim 4 and comprising a second ring spaced from said end ring, said strands being fixed to an inside surface of said second ring, and spaced from an outside surface of said second ring, and extending normal to said second ring.

6. The crown in accordance with claim 5 wherein said end ring and said second ring are of equal inside and outside diameters.

7. The crown in accordance with claim 4 wherein said strand distal pointed ends extend generally toward the first end.

8. The crown in accordance with claim 6 and comprising a retaining ring mounted on the strand curved second end portions to restrain outward movement of said strand distal ends.

9. The crown in accordance with claim 8 wherein said retaining ring is severable to permit the outward movement of said strand distal ends.

10. The crown in accordance with claim 5 wherein each of said strands is provided with a bend between said second ring and the second end portion, to provide flexibility in said strands.

11. The crown in accordance with claim 5 wherein each of said strands is provided with a coil spring portion between said second ring and the second end portion, to provide flexibility in said strands.

12. The crown in accordance with claim 4 wherein each of said strands is attached to said end ring by a spring structure.

13. A crown for surgical formation of an anastomoris, the crown comprising:

a plurality of rings having substantially equal inside and outside diameters;

a plurality of strands fixed to an inside surface of each of said rings and spaced from an outside surface of each of said rings; and

each of said strands having curved first and second end portions providing first and second distal ends extending outwardly, the distal ends being pointed;

wherein said strands are of substantially equal length and the pointed ends are disposed in circles disposed concentrically outwardly from said rings.

14. The crown in accordance with claim 13, wherein said strand first end portion distal pointed ends and said strand second end portion distal pointed ends extend generally toward each other.
