Fascial closure device
First Claim
1. A suturing device for closing a hole in a material, the suturing device comprising:
- a handle structure extending primarily along a first vector between a first coupling region and a handle region;
a guide structure extending primarily along a second vector between a second coupling region and a distraction region, the second coupling region coupled with the first coupling region, the guide structure further comprising a material capture region located between the second coupling region and the distraction region;
a needle guide cavity, extending along a needle path that originates at a needle guide portal in the first coupling region and passes only partially through the guide structure, interrupted by the capture region; and
a suture guide cavity, extending along a suture path that originates at a suture guide input portal in the first coupling region and terminates at a suture guide exit portal in the capture region,wherein the needle guide cavity comprises a needle orientation feature having an asymmetric structural feature that interfaces with a corresponding feature on a needle to rotationally guide the needle into only a single orientation when the needle is fully inserted into the needle guide cavity, the single orientation corresponding to an eye of the needle being rotationally aligned with the suture exit portal.

Abstract
Embodiments include systems and methods for closure of a hole or other defect, for example in context of a laparoscopic surgical procedure. For example, a suturing device and method of use involve inserting the device into a hole, positioning material around the hole into a notch of the device, passing a needle through a cavity in the device and the material positioned in the notch, passing a suture through the eye of the needle, and removing the needle from the material with the suture. The suture can be removed and the process can be repeated with another end of the suture at another location through the material, around the hole. When the suture is passed through the second point of penetration, the suture can now extend both into and out of the material at different points around the hole and can be tied, thereby closing the hole.
