1. A delivery device for delivering multiple implants, the device comprising:
an inner shaft comprising a proximal end, a distal end, and a lumen extending from the proximal end to the distal end;
an outer sheath having a proximal end, a distal end, and a second lumen extending from the proximal end of the outer sheath to the distal end of the outer sheath, the outer sheath being moveable relative to the inner shaft;
a rotary deployment handle configured to cause movement of the outer sheath relative to the inner shaft so as to facilitate delivery of multiple implants carried by the inner shaft at spaced-apart locations along the inner shaft, wherein the rotary deployment handle comprises:
a thumbwheel;
a belt and pulley assembly operably coupled to the thumbwheel and to the outer sheath such that rotation of the thumbwheel in a first rotational direction causes movement of the outer sheath relative to the inner shaft;
a lockout assembly configured to:
(a) cause the thumbwheel to transition from a locked configuration in which the thumbwheel is unable to rotate to an unlocked configuration in which the thumbwheel is able to rotate and
(b) tension the belt during the transition from the locked configuration to the unlocked configuration; and
a re-sheath assembly configured to facilitate re-sheathing of the inner shaft by pulling a re-sheath housing that is coupled to the inner shaft in a proximal direction, thereby moving the inner shaft relative to the outer sheath;
wherein the lockout assembly comprises a lockout lever, the lockout lever comprising a proximal end portion configured to extend out of a main housing of the rotary deployment handle when the lockout assembly is in a locked configuration and a distal end fixedly coupled to the main housing of the rotary deployment handle; and
wherein the lockout assembly further comprises a lockout plate comprising a proximal abutment surface configured to interface with a protrusion of the lockout lever and multiple engagement members configured to interface with one or more recesses between a plurality of teeth of the thumbwheel so as to prevent rotation of the thumbwheel when the lockout assembly is in the locked configuration, wherein the lockout plate is biased to move toward a proximal end of the rotary deployment handle by a spring.
