Improved medical suturing devices, systems, and methods for maintaining a position and orientation of a suture needle at a fixed location relative to a suturing device. An exemplary device include a clamp having opposing grasping surfaces for grasping the needle at a first location, and a needle contacting surface for contacting the needle at a second location, the second location a distance axially away from the first location so as to inhibit unintended movement of the needle relative to the device, which may include rotation of the needle about the first location and rotation of the needle about its axis. In many embodiments, the device includes a first and second clamp and a mechanism for alternating grasping of the needle between the first and second clamp. The device may also be incorporated into a single-clamp needle grasping device. |
