Extrusion and evaluation of degradation rate and porosity of small diameter collagen tubes
… based on natural materials. The small diameter collagen tubes were extruded using bovine collagen type I. The biodegradation rate was determined and compared for small diameter collagen tubes crosslinked with glutaraldehyde and N-(3-dimethylaminopropyl)-N'-ethylcarbodiimide hydrochloride (EDC) …

Evaluation of effect of extrusion process variables on mechanical properties of extruded collagen tubes and effect of post extrusion treatments
… variable on mechanical properties of extruded collagen tubes made using a specialized extruder, made by ZOKO Corporation of Czechoslovakia. Three extrusion variables were considered; extrusion speed, linear draw rate and rotation speed. Using Taguchi L_4 matrix, a design of experiment (DOE) was …

Peripheral nerve regeneration through collagen devices with different in vivo degradation characteristics
… materials have been used to fabricate the tubes used to bridge the stumps of a transected nerve, and collagen tubes have been specifically shown to improve the quality of regeneration. The optimal characteristics for the tube have yet to be identified, and a collagen device that can be …

Proteomic comparison of biomaterial implants for regeneration of peripheral nerve tissue
… At gap lengths >/=10 mm, impermeable silicone tubes promote little to no nerve regenerate unlike its porous, degradable collagen alternative. This study assayed rat sciatic nerve wounds treated with silicone and collagen tubes at a 14-day time point for concentration differences in transforming …

Dense Collagen Materials and the Modulation of Fibrillogenesis for Tissue Engineering
… This thesis presents a platform of densified collagen scaffolds that bridges the gap between synthetic materials and living tissue. A scalable, material-based absorptive-deformation process removes interstitial water from neutralised type I collagen in a single step, concentrating the matrix …
