A hand-operated tool for embossing a membrane or other soft pliable implant with microgrooves or microgeometries is disclosed. The tool includes an embossing surface such as a pressure plate or roller that includes a specific microgroove or microtopographical pattern. This allows a user such as a clinician to create an embossed surface on a membrane or other implantable device at the time of surgery for the purposes of directing cellular orientation and migration, increasing cell migration velocity and enhancing re-epithelialization rates in various medical and dental applications. 1. An autoclavable implant embosser tool , comprising:a first pressure plate;a second pressure plate, wherein the first pressure plate and the second pressure plate are disposed pivotally with respect to one another;wherein the first pressure plate comprises a surface comprising a first plurality of microgrooves,wherein each of the first plurality of microgrooves has a first height, a first width, and a first pitch, andwherein the first height, the first width, and the first pitch are selected to orient cells in a manner that will enhance re-epithelialization rates, direct cellular orientation and migration, and increase cell migration velocity after surgical implantation of an implant embossed by the manually-operated autoclavable implant embosser, andwherein the tool is configured to be held in a user's hand.2. The tool of claim 1 , further comprising a first elongated member on which the first pressure plate is disposed claim 1 , and a second elongated member on which the second pressure plate is disposed claim 1 , wherein the first elongated member and the second elongated member are pivotally-connected to one another.3. The tool of claim 1 , wherein the second pressure plate comprises a surface comprising a second plurality of microgrooves.4. The tool of claim 1 , wherein the first plurality of microgrooves are arranged in a pattern consisting of a first set of parallel lines.5. The ...
