Patent ID: 8715302

Claim:
A ligature delivery system for use with a left atrial appendage ligature assembly, the ligature delivery system comprising: a thread delivery mechanism comprising a cinchable loop that receives a thread of the ligature assembly and that rotates axially about a central longitudinal axis between a first configuration whereby the thread is shielded from a left atrial appendage of a patient and a second configuration whereby the thread can be released onto the left atrial appendage; a delivery control mechanism that cinches the loop about the left atrial appendage and that switches the loop between the first and second configurations, wherein the delivery control mechanism comprises a first rotary drive coupled with a first section of the cinchable loop and a second rotary drive coupled with a second section of the cinchable loop, such that applied torque is transmitted between the first and second rotary drives to rotate the cinchable loop; a support mechanism having a first engagement assembly that receives a carrier of the ligature assembly, and a second engagement assembly coupled with the delivery control mechanism; a deflector mechanism that pivots relative to the support mechanism and that is coupled with the loop; and a deflection control mechanism having an actuation assembly and a linkage assembly, wherein the linkage assembly is coupled with the actuation assembly and the deflector mechanism, such that movement of the actuation assembly relative to the support mechanism causes the deflector body and loop to pivot relative to the support mechanism.
