A fastener delivery tool may comprise a sheath assembly having at least one position retention member proximate a distal end of the sheath assembly, and a handle assembly coupled to a proximal end of the sheath assembly, the handle assembly comprising a housing, a trigger handle, and an insert connector. An external force applied to the trigger handle may cause displacement of the trigger handle relative to a rest position, and displacement of the trigger handle from the rest position within a first displacement range may impart a first amount of force on the insert connector relative to the applied external force and displacement of the trigger handle from the rest position within a second displacement range may impart a second amount of force on the insert connector relative to the applied external force, with the first amount of force being greater than the second amount of force.

A magnetically detachable stapler device is provided that utilizes a bottom housing having a first magnetic coupling element. The first magnetic coupling element utilizes a first low friction material layer disposed thereupon. The stapler device utilizes a top housing having a coupling base structure, a magazine and a hammer. At least one of the top housing, the magazine and the hammer moves relative the coupling base structure. The coupling base structure utilizes a second magnetic coupling element which itself has a second low friction material layer disposed thereupon.
