Device for soft tissue repair or replacement
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.
1. A composite implantable tissue attachment device, the device comprising:
a) a single-piece mechanical reinforcing component made of woven fibers comprising:
a central portion defining a length, a first width, and a depth, wherein the depth is less than the first width;
a first terminal portion; and
a single second terminal portion,
wherein the first terminal portion and the second terminal portion each define a second width, and wherein the second width is less than the first width, and
wherein the central portion defines a first porosity and each of the first terminal portion and second terminal portion define a second porosity that is less than the first porosity;
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 discrete and layered directly upon opposite sides of the mechanical reinforcing component.
