Methods of making collagen fiber medical constructs and related medical constructs, including patches
Implantable medical constructs formed by winding using winding support structures that can be flexible and can be integrated into the medical construct with biocompatible fiber(s) and/or yarn(s) and at least one continuous length collagen fiber. The implantable medical construct can include open suture anchor apertures formed using posts during a winding sequence.
1. A medical patch, comprising:
a patch body comprising a perimeter with a first side and an opposing second side, each of the first and second sides having an outer edge portion, wherein each outer edge portion comprises a first biocompatible fiber and/or yarn extending parallel to the first and second sides;
at least one continuous length collagen fiber that extends a plurality of times across the patch body in a mesh pattern having a plurality of overlying layers defining interstitial spaces and at least a portion of the at least one continuous length collagen fiber extends in a range of about 345 degrees to about 360 degrees about an outer surface of the at least one first biocompatible fiber and/or yarn of the outer edge portion of the first and second sides; and
a second biocompatible fiber and/or yarn residing within the patch body between the plurality of overlying layers of the mesh pattern, positioned inwardly and spaced apart from the outer edge portion of the first and second sides.
2. The medical patch of claim 1 , wherein the first biocompatible fiber and/or yarn has a diameter that is greater than a diameter of the at least one continuous length collagen fiber.
3. The medical patch of claim 1 , further comprising at least one suture anchor aperture in the mesh pattern, wherein the at least one suture anchor aperture has a size greater than the interstitial spaces to thereby allow a suture to pass therethrough.
4. The medical patch of claim 1 , further comprising a plurality of loops of the second biocompatible fiber and/or yarn extending between and/or outside the outer edge portions of the first and second sides of the patch body.
5. The medical patch of claim 4 , wherein one or more of the plurality of loops reside within the patch body and define at least one suture anchor aperture.
6. The medical patch of claim 4 , wherein one or more of the plurality of loops reside outside the patch body and have a closed-circle loop shape.
7. The medical patch of claim 1 , wherein the patch body further comprises a third side, the at least one continuous length collagen fiber further extending a plurality of times across the patch body and about the third side of the patch body to form the mesh pattern.
8. The medical patch of claim 1 , wherein the patch body further comprises an inner layer comprising the second biocompatible fiber and/or yarn arranged in a fiber grid pattern under the mesh pattern.
