1. A method of retrieving an object from a body, the method comprising:
inserting a medical device with a working channel into the body;
extending a sheath, an expandable wire loop, a net coupled to the expandable wire loop, and a fastening mechanism coupled to the net, through the working channel, and distally of the medical device, wherein the expandable wire loop further comprises a capsule;
placing the net around the object;
actuating an actuator on a handle, wherein the actuator is moveable in a proximal or a distal direction relative to a body of the handle, and wherein, after placing the net around the object, the actuator is moved proximally to at least partially close the expandable wire loop;
wherein, after placing the net around the object, moving the actuator further proximally moves the expandable wire loop partially within the capsule;
applying a pulling force on the fastening mechanism to close at least a portion of the net around the object; and
decoupling the expandable wire loop, the net, and the object from the sheath by actuating a drive wire coupled to the expandable wire loop, wherein the drive wire is configured to move the expandable wire loop relative to the sheath.
