Abstract
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.
Claims13
A manually-operated autoclavable implant embosser tool, comprising:
- a first elongated member;
- a second elongated member pivotally connected to the first elongated member;
- a first pressure plate disposed on a distal end of the first elongated member;
- a second pressure plate disposed on a distal end of the second elongated member;
- wherein the first pressure plate comprises a surface comprising a first plurality of microgrooves or microtopographies,
- wherein each of the first plurality of microgrooves has a first height, a first width, and a first pitch, and
- wherein 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;
- comprising a first finger loop disposed on the first elongated member and a second finger loop disposed on the second elongated member;
- wherein the first height is between 8 and 12 micron and the first width is between 8 and 12 micron.
