Skin compression device and methods of production and use thereof
Skin compression devices are disclosed that are formed of a shape memory material and that have multiple tensioning members. Disposal of one or more skin compression devices on the skin of a subject increases the temperature of the shape memory material and causes the tensioning members to bend inward, thereby compressing the area of skin disposed between the tensioning members; this compression shields the compressed skin from tensile loading. Methods of production and use of the skin compression devices are also disclosed.
1. A skin compression device for shielding a skin of a subject from tensile loading, the skin compression device comprising:
a first tensioning member having a first end and a second end and being formed of a shape memory alloy;
a second tensioning member having a first end and a second end and being formed of a shape memory alloy;
a supporting member connects the first end of the first tensioning member to the first end of the second tensioning member, wherein the supporting member has a first end that is connected to the first end of the first tensioning member and a second end that is connected to the first end of the second tensioning member, and wherein the first and second tensioning members extend from the supporting member at an angle of at least about 90° such that the skin compression device is substantially bracket- or U-shaped;
a bonding material applied to a lower surface of the first and second tensioning members for adhering the skin compression device to the skin of the subject;
wherein the skin compression device is configured for disposal on the skin of the subject such that the skin compression device adheres to a substantially bracket or U-shaped area of skin; and
wherein disposal of the skin compression device on the skin increases the temperature of the shape memory alloy, thereby causing the first and second tensioning members to deform and move toward one another and thus compress the substantially bracket or U-shaped area of skin disposed between the first and second tensioning members.
2. The skin compression device of claim 1 , wherein the shape memory alloy is a nickel-titanium alloy.
3. The skin compression device of claim 2 , wherein the nickel-titanium alloy is nitinol.
4. The skin compression device of claim 1 , further comprising an antimicrobial agent associated therewith.
5. The skin compression device of claim 1 , wherein the first and second tensioning members are disposed substantially parallel to one another.
6. The skin compression device of claim 1 , wherein the first and second tensioning members extend from the supporting member at an angle greater than 90°.
7. An assembly comprising two or more of the skin compression devices of claim 1 .
8. A kit, comprising:
at least one skin compression device of claim 1 ; and
a bonding material for adhering the at least one skin compression device to the skin of a subject.
9. The kit of claim 8 , further defined as comprising a plurality of skin compression devices.
10. The kit of claim 8 , further comprising an antimicrobial agent.
11. The skin compression device of claim 1 , wherein at least a portion of the supporting member is formed of a non-shape memory material.
12. A method of treating a subject, the method comprising the steps of:
affixing at least one skin compression device of claim 1 to the skin of the subject, wherein a surface temperature of the skin of the subject is greater than an ambient temperature; and
allowing the temperature of the skin to increase the temperature of the shape memory alloy of the skin compression device, thereby causing the first and second tensioning members to deform and move toward one another and thus compress an area of skin disposed between the first and second tensioning members to shield the compressed skin from tensile loading.
13. The method of claim 12 , wherein the at least one skin compression device further comprises an antimicrobial agent associated therewith.
14. The method of claim 12 , wherein the first and second tensioning members are disposed substantially parallel to one another.
15. The method of claim 12 , wherein the first and second tensioning members extend from the supporting member at an angle greater than 90°.
16. The method of claim 12 , wherein the step of affixing is further defined as affixing two skin compression devices to the skin of the subject.
17. The method of claim 12 , wherein the area of skin disposed between the first and second tensioning members comprises a wound.
18. The method of claim 12 , wherein the area of skin disposed between the first and second tensioning members has at least one percutaneous device extending therethrough.
19. The method of claim 12 , wherein the shape memory alloy of the first and second tensioning members is a nickel-titanium alloy.
20. The method of claim 12 , wherein the nickel-titanium alloy is nitinol.
