Abstract
A system for anastomosing a first tubular structure to a second tubular structure having an opening formed therein comprises a support device having a plurality of arms forming spaces therebetween. The support device is adapted to support the first tubular structure within an opening in the second tubular structure to facilitate anastomosing the tubular structures together. The arms can be configured to urge the first tubular structure against the portion of the second tubular structure surrounding the opening to form a seal therebetween. According to one embodiment, a plurality of discrete fasteners are provided to pass through the support device spaces and the first and second tubular structures.

41. A method of anastomosing a first tubular structure having an end portion to a second tubular structure having an opening formed therein where at least one of the structures comprises tissue, the method comprising:
-
everting the end portion of the first tubular structure over a support device including a plurality of arms, each having a proximal end and a distal end;
positioning the support device so that a portion of the first tubular structure forms a seal with a portion of the second tubular structure surrounding the opening therein;
passing a plurality of fasteners between selected arms and through the tubular structures in the vicinity of the opening to secure the tubular structures together; and
removing the support member from the tubular structures. - View Dependent Claims (42, 43, 44, 45, 46)

47. A method of anastomosing a first tubular structure having an end portion to a second tubular structure having an opening formed therein, where at least one of the structures is tissue, the method comprising:
-
providing a support device including a plurality of arms having a proximal end, a distal end, and a plurality of piercing members extending therefrom;
securing the first tubular structure to the plurality of piercing members;
positioning the support device so that the tubular structures contact one another;
passing a plurality of surgical fasteners between selected arms of the support device and through the tubular structures to secure the tubular structures together; and
removing the support device from the tubular structures. - View Dependent Claims (48, 49, 50, 51, 52, 53, 54, 55, 56, 57)

58. A method of anastomosing a first tubular structure having an end portion to a second tubular structure having an opening formed therein, where at least one of the structures is tissue, the method comprising:
-
providing a support device including a plurality of arms having a proximal end, a distal end, and a plurality of piercing members having a first deformed shape and a second looped memory shape;
securing the first tubular structure to the plurality of piercing members;
securing the second tubular structure to the plurality of piercing members; and
removing the support device from said piercing members and allowing the piercing members to return to their second memory loop shape.

59. A method of anastomosing a first tubular structure, having an end portion, to a second tubular structure, having fluid flowing therethrough, comprising:
-
forming an opening in the second tubular structure, while maintaining fluid flow therethrough;
placing the end portion of the first tubular structure in the opening in the second tubular structure such that a seal is formed between the first tubular structure and the second tubular structure, while maintaining fluid flow through the first tubular structure, and securing the first tubular structure to the second tubular structure with fasteners. - View Dependent Claims (60, 61, 62)

63. A method of anastomosing a first tubular structure, having an end portion, to a second tubular structure, having fluid flowing therethrough, comprising:
-
placing the end portion of the first tubular structure in an opening formed in the second tubular structure such that a seal is formed between the first tubular structure and the second tubular structure;
securing the first tubular structure to the second tubular structure with fasteners; and
performing the foregoing steps without clamping the second tubular structure to interrupt fluid flow therethrough. - View Dependent Claims (64, 65, 66)
