Lattice stitch surgical tensioning device with horizontal patency
First Claim
1. A lattice stitch surgical tension-limiting device configured to be placed on a surface of a body tissue between a length of suture and the surface of said body tissue comprising:
- a continuously flexible elongated member having a cylindrical cross sectional shape in at least one sectional axis of a body of said member;
at least one patency extending though an entire length of the body of the member in an orientation substantially along the rotational axis of said member;
an interior surface formed by an inner wall surface of said at least one patency, extending to each opening of said at least one patency;
a patency mouth located at each opening of said patency;
an exterior surface of the member defined by all surfaces of the member except the interior surface;
wherein each patency mouth is a portion of the exterior surface of the member adjoining the interior surface of said member;
said at least one patency configured to receive and retain a portion of suture used to make a lattice stitch so that the portion of suture extends along the entire length of the body of said member, andwherein said patency mouth is configured to interface with and allow movement of suture material on a surface of said patency mouth, andwherein a portion of the member is configured to move closer to an edge of a wound than remaining portions of said member, when said member is under an influence of a force exerted by a length of suture placed on the exterior surface of said member; and
wherein force exerted by a length of suture on a portion of the patency mouth of said member causes a conformation change in said member near the patency mouth.

Abstract
A lattice stitch surgical tension-limiting device, designed to be used in lattice stitch repair of wounds in biologic tissue. The device is tied to the surface of biologic tissue to be repaired by a lattice stitch. The device is designed to limit the tension in the lattice stitch, to allow placement of the lattice stitch without the need of an assistant and “instrument tie”, to help displace tension away from the surface of the body tissues, to enhance the properties of the lattice stitch in tissue shear reduction, and manage rotational forces affecting the repair as the lattice stitch draws the wound together to a closed condition. The device remains on the tissue surface during the wound healing period and is removed with the lattice stitch when wound healing is complete.
