Device for soft tissue repair or replacement
First Claim
1. A composite implantable tissue attachment device comprising:
- a) a mechanical reinforcing component made of woven fibers, consisting of;
i. a central portion defining a length, a first width, and a depth, wherein the first width is at least about 1 millimeter along at least a portion of the length and the depth is less than the first width, at least a portion of the central portion defining a porosity; and
ii. a single first terminal portion and a single second terminal portion; and
b) a first planar cellular scaffold component that overlays the central portion but not the first and second terminal portions of the mechanical reinforcing component; and
c) a second planar cellular scaffold component that overlays the central portion but not the first and second terminal portions of the mechanical reinforcing component;
wherein the first and second cellular scaffold components are shaped to match the shape of the central portion of the mechanical reinforcing component, the first and second cellular scaffold components are secured to a portion of a periphery of the reinforcing component by stitching such that the portion of periphery of the reinforcing component is stitched to a periphery of the first and second cellular scaffold components and the first and second cellular scaffold components are discrete and layered directly upon opposite sites of the mechanical reinforcing component.

Abstract
Disclosed are composite implantable tissue attachment devices comprising a mechanical reinforcing component and a cellular scaffold component. Disclosed devices include a wide, relatively flat portion for supporting long term repair of tissue. Disclosed devices can include a tapered portion at the end of the wide portions that can lead into a narrower elongated extension for aiding in placement of the device during a surgical procedure. The wide portion of the device can provide tensile strength along the longitudinal axis of the device as well as porosity. The wide devices can cover a larger surface area of a delivery site than standard suture. Disclosed materials can be utilized in, e.g., soft tissue repair such as tendon and ligament reconstruction and repair.
