Patent ID: 7452363

Claim:
A system comprising an applier with an anastomosis ring device having proximal, center, and distal rings connected respectively b proximal and distal hinged arms, the ring device having a generally cylindrical shape when unactuated and a rivet shape when actuated, the applier comprising: an elongate implement portion; a handle connected to the implement portion; a first actuating member of the elongate implement portion having a first set of prongs internally engaged to the distal ring of the anastomosis device, the first set of prongs being configured to deflectably disengage from the distal ring of the anastomosis ring device when the anastomosis ring device is actuated; an arresting member of the elongate implement portion engaged to the proximal ring of the anastomosis device; a second actuating member of the elongate implement portion having a second set of prongs internally engaged to the center ring of the anastomosis device, the second set of prongs being configured to deflectably disengage from the center ring of the anastomosis ring device when the anastomosis ring device is actuated; and first control coupled to the handle operably configured to cause proximal movement of the first actuating member and the distal ring engaged thereto toward the arresting member and toward the proximal ring; a second control coupled to the handle operably configured to cause proximal movement of the second actuating member and the center ring engaged thereto toward the arresting member and toward the proximal ring; wherein the first and second controls are operable to be selectively positioned to contemporaneously perform both of the following: (i) reduce a first longitudinal separation between the center ring and a selected one of the proximal and distal rings thereby causing actuating of the interposed hinged arms located between the center ring and the selected one of the proximal and distal rings of the ring device, and (ii) maintain a second longitudinal separation between the center ring and the other ring thereby preventing actuating of the interposed hinged arms located between the center ring and the other ring of the ring device to configure the anastomosis ring device into a partially actuated ring shape having one set of at least partially actuated arms and one set of unactuated arms; and wherein the first and second controls are further operable to be selectively positioned to reduce the longitudinal separation between the center ring and both the proximal ring and distal ring, causing actuating of all of the hinged arms of the anastomosis ring device.
