Title: Jeff Cohen: Innovator in Bioprosthetic Tissue Conditioning

Introduction

Jeff Cohen is a notable inventor based in Irvine, CA (US). He has made significant contributions to the field of bioprosthetic materials, holding 2 patents that focus on innovative methods for conditioning sheet bioprosthetic tissue.

Latest Patents

Cohen's latest patents involve advanced techniques for conditioning bioprosthetic materials, specifically utilizing bovine pericardial membrane. One of the methods employs a laser directed at the fibrous surface of the membrane, which is moved relative to the surface to reduce its thickness to a specific uniform level while smoothing it. The selection of the laser's wavelength, power, and pulse rate is crucial for achieving the desired surface smoothness and appropriate thickness. Alternatively, a dermatome can be used to remove a layer of material from the fibrous surface. Compression techniques are also employed, with stepwise compression combined with cross-linking to stabilize the membrane and prevent damage from inelastic compression. These various thinning techniques can be utilized together to create strong, thin membranes.
