Devices, methods, and kits are provided for suturing an end of a first body duct to a hole in the side of a second body duct. The present devices and methods are used to simplify the suturing procedure and thus reduce operating time. In one embodiment, the present device includes a structure for holding the end of the first body duct and positioning the end adjacent to the hole in the side of the second body duct. The structure of the device is typically a shaft having a surface adapted to receive the first body duct. A plurality of needles are arranged on the structure to be advanced along a plurality of paths. Each needle path first passes radially into and forwardly out of the end of the first body duct and into the hole of the second body duct. The path then everts so that the needles and associated sutures will pass outwardly through tissue peripheral to the hole when the end of the first body duct is on the structure adjacent to the hole in the second body duct. The needles preferably travel along such paths when they are advanced forward. In one embodiment, the device uses a J-shaped tube for guiding one of the needles along the desired path. In another embodiment, shape-memory needles having an arcuate profile are used to create the desired path.

A device as in claim 1, wherein the shaft comprises a plurality of guide channels which define said plurality of paths. 7. A device as in claim 6, wherein the guide channels are arranged in a radial configuration about the shaft. 8. A device as in claim 6, wherein the guide channels comprise guide tubes. 9. A device as in claim 6, wherein the guide channels have a longitudinal slot along a length of at least of one said guide channels. 10. A device as in claim 6, wherein the guide channels each have a first portion and a second portion, wherein the first and second portions are separated by a gap configured to receive the end of the first body duct. 11. A device as in claim 10, wherein the second portion of the guide channel comprises a guide tube having a J-shaped section for guiding one of said needles along a portion of said path. 12. A device as in claim 11, wherein the second portion of the guide channel tube has a longitudinal slot extending along the length of the guide tube having a j-shaped section. 13. A device as in claim 10, wherein: the first portion of the guide channel is adapted to be positioned outside the first body duct and has a distal opening positioned to open towards an outer surface of the first body duct when the first body duct is mounted on the shaft; and the second portion of the guide channel is adapted to be positioned within a lumen of the first body duct when the first body duct is mounted on the shaft, said second portion of the guide channel receiving one of said needles advanced from the first portion and passing through a body duct wall. 14. A device as in claim 13, wherein the second portion of the guide channel has a j-shaped configuration. 15. A device as in claim 13, wherein the second portion of the guide channel includes a longitudinal slot extending the length of the second portion. 16. A device as in claim 13, wherein the needles are of sufficient length to extend from the first portion of the guide channel, through the second portion, and through a tissue layer of the second body duct. 17. A device as in claim 6, wherein at least one of said guide channels has a substantially curved configuration so that one of said needles passing through said guide channel will evert to pass outwardly through tissue peripheral to the hole when the end of the first body duct is on the shaft adjacent to the hole in the second body duct. 18. A device as in claim 1, wherein said needles comprise a shape-memory alloy. 19. A device as in claim 1, wherein said needles comprise a superelastic material. 20.
