Abstract

A method of manufacturing a surgical device including providing a substrate having opposite first and second sides. The second side having a first section and a second section. Coupling a substrate to a fixture such that the first side faces the fixture and depositing a gel onto the second side such that the gel coats the first section without coating the second section.

First claim

What is claimed is:

1. A method of manufacturing a surgical device, the method comprising:
providing a substrate having opposite first and second sides, the second side having a first section and a second section;
coupling a substrate to a fixture such that the first side faces the fixture; and
depositing a gel onto the second side such that the gel coats the first section without coating the second section, the gel comprising a hemostatic agent suspended in a solution, the solution comprising collagen, water and glycerol.

2. The method recited in claim 1 , wherein depositing the gel onto the second side comprises 3D printing the gel onto the second side.

3. The method recited in claim 1 , wherein depositing the gel onto the second side is controlled by a robot.

4. The method recited in claim 1 , wherein the first section comprises a plurality of first sections that are spaced apart from one another by the second section.

5. The method recited in claim 1 , wherein the first section comprises a plurality of first sections that are spaced apart from one another by the second section, the first sections each having the same shape.

6. The method recited in claim 1 , wherein the first section comprises a plurality of first rows that are spaced apart from one another by the second section.

7. The method recited in claim 1 , wherein depositing the gel onto the second side includes depositing a first gel onto the second side and depositing a second gel onto the first side, the first gel having a color that is different than a color of the second gel.

8. The method recited in claim 1 , wherein the substrate is an absorbable antibacterial envelope.

9. The method recited in claim 1 , wherein the gel consists of the hemostatic agent suspended in solution, the solution consisting of collagen, water and glycerol.

10. The method recited in claim 1 , wherein the hemostatic agent comprises trans-4-(aminomethyl)cyclohexanecarboxylic acid (C 8 H 15 NO 2 ).

11. The method recited in claim 1 , wherein the hemostatic agent consists of trans-4-(aminomethyl)cyclohexanecarboxylic acid (C 8 H 15 NO 2 ).

12. The method recited in claim 1 , wherein the first section defines at least a portion of a perimeter of the substrate.

13. The method recited in claim 1 , wherein the hemostatic agent includes epinephrine.

14. The method recited in claim 1 , wherein the hemostatic agent includes tranexamic acid.

15. The method recited in claim 1 , wherein the hemostatic agent includes collagen.

16. The method recited in claim 1 , wherein the hemostatic agent includes acid soluble collagen.

17. The method recited in claim 1 , wherein the hemostatic agent includes chitosan.

18. The method recited in claim 1 , wherein the hemostatic agent includes oxidized regenerated cellulose.

19. A method of manufacturing a surgical device, the method comprising:
providing a substrate having opposite first and second sides, the second side having a first section and a second section, wherein the substrate is an absorbable antibacterial envelope;
coupling a substrate to a fixture such that the first side faces the fixture; and
3D printing a gel onto the second side such that the gel coats the first section without coating the second section,
wherein the first section comprises a plurality of first sections that are spaced apart from one another by the second section, and
wherein the gel consists of trans-4-(aminomethyl)cyclohexanecarboxylic acid (C 8 H 15 NO 2 ) suspended in a solution, the solution consisting of collagen, water and glycerol.

20. A method of manufacturing a surgical device, the method comprising:
providing a substrate having opposite first and second sides, the second side having a first section and a second section, wherein the substrate is an absorbable antibacterial envelope;
coupling a substrate to a fixture such that the first side faces the fixture; and
depositing a gel onto the second side using a robot such that the gel coats the first section without coating the second section,
wherein the first section comprises a plurality of first sections that are spaced apart from one another by the second section, and
wherein the gel consists of trans-4-(aminomethyl)cyclohexanecarboxylic acid (C 8 H 15 NO 2 ) suspended in a solution, the solution consisting of collagen, water and glycerol.
