US Patent 9326765 Suturing device having an internal suture dispensing mechanism

A device for suturing tissue includes a handle that has a proximal end and a distal end. The device also includes a generally hollow suturing needle including a pointed distal end, an opposite proximal end and an inner lumen having an suture exit port through which the suture exits. The device further includes a suture dispensing mechanism disposed within the handle and including an actuator which when manipulated by a user is configured to advance suture material within the handle such that the suture material is guided into the inner lumen of the hollow suturing needle and exits through the suture exit port. The device includes a safety mechanism that shields at least a portion of the needle.
