Surgical suturing instrument and method for use

Abstract

A device is disclosed for introducing a flexible elongated element through at least two portions of a subject. The device includes an advancement unit for advancing the flexible elongated element toward the end of the device such that the elongated element may exit from the device with sufficient force to pass through the subject. The device also includes a curved die for imparting a looping configuration to portions of the flexible elongated element exiting the device, and a curved guide for receiving the looped flexible elongated element as it returns to the end of the device. A cutting mechanism is provided to permit the looped flexible elongated element to be separated from the remainder of the flexible elongated element. The cutting mechanism is adapted to deform the trailing end of the looped flexible elongated element so that the trailing end is forced distally, toward the subject being sutured.

1 . A suturing instrument comprising: 
 a handle;    a shaft extending from the handle and having a proximal end and a distal end including an opening;    a channel shaped to impart a curvature to the suture wire as the suture wire moves in the channel;    a cutter adapted to cut the suture wire; and    a wire drive located near the distal end of the shaft that, when actuated, engages with and moves the suture wire in the channel;    wherein the suture wire forms a wire loop suture when moved out of the opening.
