Foam-formed collagen strand
First Claim
1. A foam-formed human collagen strand material comprising a matrix of reticulated pores, said strand material formed by depositing a dispersed solution of human collagen strands on a template, the reticulated pores having a pore size ranging from greater than 0.6 mm to less than 2.0 mm, wherein the matrix of reticulated pores comprises a plurality of fenestrations oriented in a first direction providing channels configured to conduct fluid and cell movement within and throughout the foam-formed human collagen strand material;
- said material comprising the matrix of reticulated pores further comprising a surface being embossed to form a surface topography wherein matrices of intersecting embossed surface channels include an axial channel extending between an embossed top surface channel intersection point and an embossed bottom surface channel intersection point.

Abstract
Foam-formed collagen strands and methods for forming strands involve depositing a dispersed solution of an isolated cleaned, de-fatted, enzymatically-treated (or non-enzyme treated) human-derived collagen product having a preserved amount of its natural constituents into grooves of a grooved plate, and processing the dispersed collagen product to provide a foam-formed collagen strand. Foam-formed collagen strands may be processed into threads having a matrix of reticulated pores to conduct biological materials in and through the strand, the collagen of the collagen strand comprising isolated, enzymatically-treated human derived collagen having a preserved amount of its natural collagen constituents.
