Abstract

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.

Claims (23)

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, wherein the first end of the second tensioning member is directly connected to the first end of the first tensioning member, and wherein the second end of the second tensioning member is disposed a distance from the second end of the first tensioning member such that the skin compression device is substantially V-shaped; wherein the directly connected first ends of the first and second tensioning members form an acute angle of the substantially V-shaped skin compression device; 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 first and second tensioning members adhere to a substantially V-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 V-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. An assembly comprising two or more of the skin compression devices of claim 1 .

6. 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 the area of skin disposed between the first and second tensioning members to shield the compressed skin from tensile loading.

7. The method of claim 6 , wherein the area of skin disposed between the first and second tensioning members comprises a wound.

8. The method of claim 6 , wherein the area of skin disposed between the first and second tensioning members has at least one percutaneous device extending therethrough.

9. The method of claim 6 , wherein the shape memory alloy of the first and second tensioning members is a nickel-titanium alloy.

10. The method of claim 9 , wherein the nickel-titanium alloy is nitinol.

11. The method of claim 6 , wherein the at least one skin compression device further comprises an antimicrobial agent associated therewith.

12. The method of claim 6 , wherein the step of affixing is further defined as affixing two skin compression devices to the skin of the subject.

13. 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.

14. The kit of claim 13 , further defined as comprising a plurality of skin compression devices.

15. The kit of claim 13 , further comprising an antimicrobial agent.
