Abstract
Medical suturing devices, systems, and methods will be useful for endoscopic (with or without access ports) or other surgeries in which access is limited, including ear, nose, and throat procedures. Articulation motions may be transferred from a handle to needle grasping jaws using an axial movement of a shaft that has axial stiffness (such as being stiff in compression) and lateral flexibility or an axial movement of a cable. An extension body (within which the shaft or cable moves) between the handle and jaws can be pre-bent or custom bent by the user. Portions of the devices may be disposable, replaceable, and/or reusable. A spring adjacent the clamp may open the clamp or impose a gripping force.
