Systems and methods for suturing tissue

A device for suturing tissue includes a handle including a housing and a suturing needle for advancing a suture through the tissue. The device also includes a first needle gripper that is configured to both grasp and release the suturing needle. A second needle gripper is also configured to both grasp and release the suturing needle. An actuator is coupled to the housing and is operatively coupled to: (a) a first linkage that pivots the second gripping gripper between a fully extended position and a retracted position relative to the housing; and (b) a second linkage that is operatively coupled to the first and second needle grippers and configured to alter a state of each of the first and second needle grippers. The second linkage can include a one-way clutch.

Means and methods for suturing tissue

A device according to one exemplary embodiment is a compact, light-weight handheld device that includes a needle and suture assembly, a mechanism for gripping and releasing the needle and suture assembly (a “needle transfer mechanism” or “needle shuttle mechanism”), safely capturing the needle assembly upon exit from the patient's tissue, and returning the needle to position such that the process of delivering additional sutures to the patient can be repeated. The device of the present invention accommodates the right or left-handed user, rests comfortably in the user's hand, allows sufficient visualization of the procedure site, and permits the user to either control penetration depth of the needle or default to a device-determined depth. The present device permits the user to utilize a wrist-rotation (pivoting) suture delivery technique that is familiar to a user based on experience with other surgical techniques.

MEDICAL DEVICE WITH GRASPING MECHANISM

A device for suturing tissue includes a handle and a suturing mechanism coupled to the handle and being configured to suture the tissue with a suture element. The device further includes a suture grasping mechanism coupled to the housing and being configured to move between an open position for receiving the suture element and a closed position for grasping and holding the suture element to permit manipulation of the suture elements, such as tying a knot. 1. A surgical device comprising:a handle having a housing, the handle being configured to perform at least a first operation; anda suture grasping mechanism that forms part of the handle and includes a first part and a second part that is movable relative to the first part and the housing to perform a second operation different than the first operation and permit the suture grasping mechanism to have an open position for receiving a suture and a closed position for grasping and holding the suture between the first part and the second part.2. A device for suturing tissue comprising:a handle having a housing;a suturing mechanism coupled to the handle and being configured to suture the tissue with a suture element; anda suture grasping mechanism coupled to the housing and being configured to move between an open position for receiving the suture element and a closed position for grasping and holding the suture element.3. The device of claim 2 , wherein the suturing mechanism includes a suturing needle that can be driven through the tissue claim 2 ,4. The device of claim 2 , wherein the suturing mechanism is disposed at a first end of the handle and the suture grasping mechanism is disposed at or proximate to an opposite second end.5. The device of claim 2 , wherein the suturing mechanism includes an actuator that is disposed along a same side of the housing as the suture grasping mechanism.6.

Ultrasonic probe assembly and cable therefor

An ultrasonic probe including a sensor head having an array of ultrasonic transducer elements is disclosed. The sensor head is located at the tip of a flexible shaft. The flexible shaft houses a flex circuit which is electrically connected directly to the transducer elements. The flex circuit transmits electrical signals from the transducer elements to the handle of the probe. The flexible shaft is bendable in all directions and can bend in a sharp radius in the region near the tip of the flexible shaft.
