An exemplary anastomosis device comprises a proximal ring, a distal ring,
and a middle ring. The middle ring has apertures configured to
communicate a fluid such as an adhesive. The exemplary anastomosis device
also has arms joining the proximal ring to the center member and arms
joining the distal ring to the center member. The anastomosis device is
configured to move from an unactuated position, where it has a generally
cylindraceous configuration, to an actuated position, where it has a
generally rivet-like configuration. The anastomosis device may be used to
provide and secure an anastomosis between adjacent tissue walls. Adhesive
may be communicated through the apertures of the middle ring of the
anastomosis device to seal or strengthen the anastomosis. An applier may
be used to deploy the anastomosis device and to communicate the adhesive
through the apertures.
