Patent ID: 7871418

Claim:
An applier for an anastomosis ring device of the type having proximal, center, and distal rings connected respectively by proximal and distal hinged arms the hinged arms having a generally oblong radially retracted shape when the ring device is un-actuated and a folded radially protruding shape when the ring device is actuated, the applier comprising: an elongate implement portion and a handle connected to the implement portion; a distal actuating member comprising catch means which, in a lock position, protrudes radially outward to engage the distal ring; a proximal actuating member adapted to engage the proximal ring; an actuation mechanism arranged at the handle and configured to cause the proximal and distal actuating members to move towards each other along a longitudinal axis (X) of the implement portion to approximate the proximal and distal rings causing actuation of the hinged arms, wherein the distal actuating member is rotatable about said longitudinal axis (X) from said lock position to a release position thereby sliding along a deviating surface at the implement portion which is configured to urge said catch means radially inward to disengage it from the distal ring; and wherein the implement portion comprises a substantially cylindrical housing with axially extending distal window slots and the distal actuating member comprises a shaft slidably received inside the housing and a plurality of distal catches protrude outward from the shaft and extend through the distal window slots such that they engage the distal ring of the anastomotic ring device when in said lock position, said distal catches being configured to be deviated radially inward by lateral edges of the distal window slots in response to rotation of the distal actuating member from said lock position to said release position.
