Surgical attachment device
View Patent ↗A hybrid medical device that can aid in reconstructive or augmentative surgery of the breast is disclosed. The device can utilize a suitable biological collagen tissue matrix combined with a synthetic material, for example, that can impart a high initial strength to the repair site while permitting proper healing and revitalization of the implanted device.
1. A method for making a surgical attachment device comprising:
removing antigenic compounds from a first biologic layer;
forming a biologic sheet from the first layer, wherein the biologic sheet has a first end and a second end;
stitching a first leader through the biologic sheet, wherein the first leader comprises a first synthetic material and wherein the first leader extends from the first end, across the sheet to the second end, and across the sheet to the first end, wherein the first end is opposite the second end, and wherein the first leader has a straight and/or curved shape; and
stitching a second leader through the biologic sheet across the first leader, wherein the second leader extends from a first edge of the sheet across the sheet to a second edge of the sheet, wherein the first edge of the sheet is opposite the second edge of the sheet, wherein the first edge of the sheet and the second edge of the sheet extend between the first end and the second end, and wherein at least a length of the second leader has a zig-zag shape that crosses over the first leader.
2. The method of claim 1 , wherein the stitching comprises stitching the first leader from the first end to the second end of the biologic sheet.
3. The method of claim 1 , further comprising stitching a second leader through the biologic sheet, wherein the second leader comprises a second synthetic material.
4. The method of claim 3 , wherein the synthetic material comprises a non-biodegradable polymer.
5. The method of claim 3 , wherein the second leader intersects the first leader.
6. The method of claim 3 , further comprising cutting a pattern out of the biologic sheet, wherein cutting comprises cutting the first leader stitched in the sheet and the second leader stitched in the sheet.
7. The method of claim 1 , wherein at least a length of the first leader has a zig-zag shape.
8. The method of claim 1 , wherein at least a length of the first leader has a sinusoidal shape.
9. The method of claim 1 , wherein the biologic sheet comprises collagen.
10. The method of claim 1 , wherein the first synthetic material comprises a non-biodegradable polymer.
11. The method of claim 1 , further comprising bonding the first layer to a second layer to at least partially form the first biologic layer.
12. The method of claim 1 , wherein the first leader comprises a monofilament.
13. The method of claim 1 , further comprising cutting a desired device shape out of the biologic sheet.
14. The method of claim 13 , wherein the cutting comprises cutting the first leader.
15. A method for making a surgical attachment device comprising:
removing antigenic compounds from at least part of a biologic sheet;
stitching a first leader through the biologic sheet, wherein the stitching of the first leader comprises stitching at least a length of the first leader in a sinusoidal and/or zig-zag shape along the plane of the sheet, wherein the first leader extends from a first end of the sheet, across the sheet to a second end of the sheet, and across the sheet to the first end of the sheet, and wherein the first end of the sheet is opposite the second end of the sheet; and
stitching a second leader through the biologic sheet, wherein the stitching of the second leader comprises stitching at least a length of the second leader in a sinusoidal and/or zig-zag shape along the plane of the sheet, and wherein the second leader extends from a first edge of the sheet across the sheet to a second edge of the sheet, wherein the first edge of the sheet is opposite the second edge of the sheet, wherein the first third edge of the sheet and the second edge of the sheet extend between the first end of the sheet and the second end of the sheet, and wherein at least a portion of the length of the second leader changes direction at least twice between two adjacent portions of the first leader.
16. The method of claim 15 , wherein the first leader and the second leader comprise a synthetic material.
17. The method of claim 15 , further comprising bonding a first layer to a second layer to at least partially form the biologic sheet.
18. The method of claim 16 , further comprising cutting a pattern out of the biologic sheet, wherein cutting comprises cutting the first leader stitched in the sheet and the second leader stitched in the sheet.
19. A method for making a support device comprising:
stitching a first leader through a biologic sheet, and wherein the stitching of the first leader comprises stitching at least a length of the first leader in a sinusoidal and/or zig-zag shape between a first end and a second end of the sheet;
stitching a second leader through the biologic sheet, wherein the stitching of the second leader comprises stitching the second leader in a sinusoidal and/or zig-zag shape in the sheet, and wherein the second leader extends from a first edge of the sheet across the sheet to a second edge of the sheet, wherein the first edge of the sheet is opposite the second edge of the sheet, wherein the first third edge of the sheet and the second edge of the sheet extend between the first end of the sheet and the second end the sheet, wherein the second leader changes direction between two adjacent portions of the first leader, and wherein the second leader extends over the two adjacent portions of the first leader; and
cutting a pattern out of the biologic sheet, wherein cutting comprises cutting the first leader stitched in the sheet and the second leader stitched in the sheet.
