Unitary surgical device and method
First Claim
1. A unitary surgical device for implantation in a patient for repairing a body tissue in the patient, the unitary surgical device comprising:
- a first biocompatible anchor including at least one of the following;
a bioresorbable barbed dart;
a bioresorbable tack;
a bioresorbable backstop; and
a bioresorbable male locking member;
a second biocompatible anchor including at least one of the following;
a bioresorbable barbed dart;
a bioresorbable tack;
a bioresorbable backstop; and
a bioresorbable female locking member; and
biocompatible tissue repair material extending between and connected to the first anchor and to the second anchor prior to surgery, the tissue repair material including at least one of the following;
a fixed length of suture;
a sheet of collagen-containing material;
a sheet of biologically remodelable collagenous matrix;
laminar ECM material;
formed ECM material;
comminuted ECM material;
ECM fiber;
ECM foam material;
cross-linked ECM material;
a sheet of bioresorbable material; and
a base and a different material secured to the base, at least one of the base and the different material including ECM material.

Abstract
Unitary surgical devices (10) are disclosed. One group of the illustrated devices has a pair of biocompatible, bioresorbable anchors (16, 18) connected to fixed lengths suture. The anchors (16, 18) and fixed length of suture are connected to each other prior to surgery. Another group of unitary surgical devices has a pair of fixating mechanisms (15, 17) connected to a base (21) prior to surgery. The second group of illustrated devices generally includes extracellular matrix material either as part of the base (21) or supported on the base (21). The extracellular matrix material serves as tissue regenerating material. In the second group of unitary surgical devices, the fixating mechanisms illustrated generally comprise suture, anchors or pre-formed holes in the base. All of the illustrated unitary surgical devices are useful in repairing a damaged meniscus. The first group of unitary surgical devices can be used to approximate inner surfaces of a tear in the meniscus. The second group of devices can be used either as an insert to be placed between and approximated to the inner surfaces of the tear or as an insert to replace a void in the meniscus left after a menisectomy.
