    摘要: A biointerface membrane for an implantable device including a nonresorbable solid portion with a plurality of interconnected cavities therein adapted to support tissue ingrowth in vivo, and a bioactive agent incorporated into the biointerface membrane and adapted to modify the tissue response is provided. The bioactive agents can be chosen to induce vascularization and/or prevent barrier cell layer formation in vivo, and are advantageous when used with implantable devices wherein solutes are transported across the device-tissue interface.

    摘要: A method of preparing a crosslinked, collagen-based medical scaffold is provided, comprising: (a) immersing a sample of fibrous and/or non-fibrous collagen in a buffered acidic, aqueous solution comprising an alcohol; (b) contacting the collagen in solution with a catalytic component comprising 1-ethyl-3-[3-dimethylaminopropyl]carbodiimide hydrochloride for a time at least sufficient to effect reaction between amino and carboxyl groups present on the collagen and to yield crosslinked collagen that is resistant to pronase degradation; and (c) drying the crosslinked collagen to yield a porous, crosslinked collagen article wherein the porous, crosslinked collagen article demonstrates a pore size of 10-500 microns. Also provided are bioactive collagen medical scaffolds for wound care dressings, hernia repair prosthetics, and surgical incision closure members, prepared using the method above.
