Abstract

Methods for transcutaneous heat transfer are provided. Aspects of the methods include stably associating a glabrous skin surface of a mammal with a thermoregulatory device configured to be associated with only a portion of a limb of the mammal and transferring heat through the glabrous skin surface without application of negative pressure. Also provided are devices, systems and kits that fmd use practicing the methods. The methods and compositions described herein find use in a variety of different applications, including maintaining normothermia, e.g., in thermoregulatory compromised individuals.

First claim

What is claimed is:

1 . A method of transcutaneous heat transfer, the method comprising:
(a) stably associating a glabrous skin surface of a mammal with a thermoregulatory device comprising a heat exchange element and an attachment element, wherein the thermoregulatory device is configured to be associated with only a portion of a limb of a mammal; and (b) transferring heat through the glabrous skin surface without application of negative pressure in a manner sufficient to achieve transcutaneous heat transfer.

2 . The method according to claim 1 , wherein the heat exchange element is a fluid heat exchange element or an electrical heat exchange element.

3 . The method according to claim 1 or 2 , wherein vasoconstriction is compromised in the glabrous skin surface.

4 . The method according to claim 3 , wherein the method further comprises compromising vasoconstriction in the glabrous skin surface.

5 . The method according to any of the preceding claims, wherein the method comprises producing anesthesia in the mammal.

6 . The method according to any of the preceding claims, wherein the glabrous skin surface comprises a palm or a sole.

7 . A thermoregulatory device configured to transfer heat through a glabrous surface of a mammal, the device comprising a heat exchange element and attachment element, wherein the thermoregulatory device is configured to be associated with only a portion of a limb of a mammal and does not include a negative pressure element.

8 . The thermoregulatory device according to claim 7 , wherein the heat exchange element is a fluid heat exchange element or an electrical heat exchange element.

9 . The thermoregulatory device according to any of claim 7 or 8 , wherein the glabrous skin surface comprises a palm a sole.

10 . The thermoregulatory device according to any of the preceding claims, wherein the mammal is a human.

11 . A system comprising:
(a) a thermoregulatory device according to any of claims 7 to 10 ; and (b) a power source operatively coupled to the thermoregulatory device.

12 . The system according to claim 11 , wherein the system further comprises a source of a temperature controlled liquid.

13 . The system according to any of claims 11 and 12 , wherein the system comprises two or more thermoregulatory devices according to any of claims 7 to 10 .

14 . A kit comprising:
a set of two or more thermoregulatory devices according to any of claims 7 to 10 .

15 . The kit according to claim 14 , wherein the kit comprises two thermoregulatory devices configured to be associated with a human hand and two thermoregulatory devices configured to associated with a human foot.
