Abstract
Anastomosis devices, methods and apparatus for installing the devices in the performance of an anastomosis. One example of a device includes a central ring portion from which malleable tines and optionally also fastener elements extend. Each tine may have a weakened section at which it preferentially folds or buckles when subjected to bending force. Each tine can grab and evert tissue around an orifice in which it is installed, as it is moved from an initial to a final configuration. To install a device, the tines are advanced against an anvil to cause them to grab tissue around the orifice and curl radially. The anvil is then retracted to fold the tines so their curled ends move radially outward.
