<p>Angled anastomosis devices and associated methodology are described herein. Connector and connector components as well as tools associated therewith are disclosed. The connectors (2) are adapted to produce an angled end-to-side anastomosis at a graft/host vessel junction. A fitting (10) alone, or a fitting (10) in combination with a collar (12) may be used as a connector (2). Each fitting (10) may be deployed by deflecting its shape to provide clearance for a rear segment (18) that rotates about adjoining hinge section(s) so as to fit the connector (2) within an aperture formed in a host vessel. Upon return to a substantially relaxed position, a trailing or heel segment (18) anchors the fitting in place. The angled fitting (10) may include additional side features for interfacing with the host vessel. The collar (12) may include features complimentary to those of a fitting (10) and provisions for securing the graft to the host vessel.</p> |
