Microtopographic pattern transfer tool
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. 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.
2. The tool of claim 1 , wherein the second pressure plate comprises a surface comprising a second plurality of microgrooves;
wherein each of the second plurality of microgrooves has a second height, a second width, and a second pitch, and
wherein the second height, the second width, and the second 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 the implant embossed by the manually-operated autoclavable implant embosser.
3. The tool of claim 1 , wherein the plurality of microgrooves are arranged in a pattern of parallel lines.
4. The tool of claim 2 , wherein the first plurality of microgrooves are arranged in a pattern consisting of a first set of parallel lines intersecting with a second set of parallel lines of the second plurality of microgrooves.
5. The implant embosser of claim 2 , wherein the first plurality of microgrooves is selected for soft tissue repair, and wherein the second plurality of microgrooves is selected for bone growth.
6. The tool of claim 1 , wherein the first plurality of microgrooves are arranged in a pattern of concentric circles.
7. The tool of claim 6 , wherein the pattern further comprises a plurality of lines emanating from a center point of the concentric circles.
8. The tool of claim 1 , wherein the surface comprises titanium.
9. The tool of claim 1 , wherein the surface comprises stainless steel.
10. The tool of claim 1 , wherein the plurality of microgrooves are arranged in a pattern.
11. The tool of claim 1 , wherein the surface comprises metal.
12. The implant embosser of claim 1 , wherein the second height is between 0.5 micron and 50 micron and the second width is between 0.05 micron and 50 micron.
13. The implant embosser of claim 1 , wherein the second height is between 8 micron and 12 micron and the second width is between 8 micron and 12 micron.
