Abstract: A device and method of delivering a medical tool which may be a resector, cutter, probe, or the like, including a memory arm compacted in a small diameter state which expands in a relaxed memory state, is disclosed. Said delivery may include using a hollow sheath to pre-compact or preload a memory blade into a compact position, transferring said compacted memory blade into a cannula, and deploying said memory blade from the distal end of said cannula whereby the memory blade returns to its normal expanded memory state and a deployment nut can be used to control the extension or the withdrawal of the memory arm and blade.

Abstract: A bidirectional torque limiting driver with a handle, internal wall, movable head and a tool mounted thereon, with flexible torque limiting flex ramp(s) formed on said internal wall, whereby said ramps move under sufficient force to impart a predetermined torque to a tip is disclosed.

Abstract: A torque-limiting device may include a shaft extending axially through upper and lower shanks and a spring to connect to a nut. The upper and lower shanks may be under a force from the spring and further configured to selectively engage within a predetermined torque limit and disengage at above the predetermined torque limit. Accordingly, the shaft may receive torque up to the predetermined limit as provided by a user operating a handle of the torque-limiting device. The torque-limiting device may be disposable, reusable, economical, and have high torque capabilities.

Abstract: A disposable ratcheting device and method is disclosed, which may include a shaft extending axially through at least a shank. The shank also provides a cup or chamber wherein a series of drive bodies reside in a movable fashion. The shank is placed in a body having an inner wall with teeth formed radially, The drive bodies have toes protruding beyond the shank and which, in a locked direction, engage the teeth inside the body.

Abstract: A clutch within a torque-limiting device which may include a shaft extending axially through a clutch assembly and a spring to connect to a nut. The clutch having swappable gear rings. The upper and lower shanks may be under a force from the spring and further configured to selectively engage within a predetermined torque limit and disengage at above the predetermined torque limit. Accordingly, the shaft may receive torque up to the predetermined limit as provided by a user operating a handle of the torque-limiting device. The torque-limiting device may be disposable, reusable, economical, and have high torque capabilities.

Abstract: A torque-limiting device may include a shaft extending axially through upper and lower shanks, a spring, and a nut to an end opening of a handle. The upper and lower shanks may be under a force from the spring and further configured to selectively engage within a predetermined torque limit and disengage at above the predetermined torque limit. Accordingly, the shaft may receive torque up to the predetermined limit as provided by a user operating a handle of the torque-limiting device. The torque-limiting device may be disposable, reusable, economical, and have high torque capabilities. The shaft may be of a plastic material and include a lumen extending there through, and through which a variety of devices and materials may be delivered to a workpiece.
