1. A ligature delivery system for applying a left atrial appendage ligature on a left atrial appendage, the ligature delivery system comprising:
an elongate support shaft having a proximal portion and a distal portion;
a handle portion located at the proximal portion of the elongate support shaft;
a flexible hoop assembly coupled with the distal portion of the elongate support shaft, the flexible hoop assembly defining a support body and a support frame, wherein the support body comprises a lumen configured to receive the support frame within; and
one or more constriction members coupled to the flexible hoop assembly, wherein the support body is configured to support the one or more constriction members, wherein the one or more constriction members are guided via a plurality of flaps of the support body, wherein the plurality of flaps define a plurality of channels in which the one or more constriction members are received; and
a deflector body configured to pivot in two axes relative to the elongate support shaft, wherein the support frame of the flexible hoop assembly is coupled with the distal portion of the elongate support shaft via the deflector body, wherein the deflector body comprises a plurality of pockets configured to hold the one or more constriction members guided from the plurality of flaps.
