Variable spread suturing device

摘要

A suturing device, and methods for suturing various sizes of apertures in tissues, are presented. The suturing device has a body with at least one or more adjustable arms that are coupled with catch targets. The arms are coupled with needle guides such that movements of the arms orient the needle guides to direct the needles towards the catch targets. The catch targets are coupled with sutures, such that when the needles reach the targets, they capture and pull the sutures back to the body. By changing the angles at which the arms extend from the body, the catch targets are moved closer to, or farther from, the body, and the suture device is readily configured to suture various sizes of apertures.

主权项

1. A suturing device that is configurable to suture various sizes of apertures, comprising:
a body having a first proximal arm and a first distal arm, a catch target coupled to the first distal arm such that a laterally outward movement of at least one of the first proximal arm and the first distal arm from the body moves the catch target away from the body; and a needle guide coupled to the first proximal arm such that the movement of the first proximal arm orients the needle guide to direct a needle towards the catch target; wherein the first proximal arm and the first distal arm are independently movable.
