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 and a plurality of piercing members slidably coupled to the arms. The support device piercing members have a retracted state and an extended state to support the first tubular structure thereon for placement 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. In another embodiment, fasteners are integrated into the support device and releasably coupled thereto for delivery to the anastomosis site.
