Generally, the methods and devices can activate BAT to increase thermogenesis, e.g., increase heat production in the patient, which over time can lead to weight loss and/or improved metabolic function. In one embodiment, a medical device is provided that activates BAT by cooling tissue having a high density of cold sensitive thermoreceptors and/or by cooling BAT depots directly, thereby increasing thermogenesis in the BAT and inducing weight loss and/or improved metabolic function through energy expenditure. ## Claims ### Claim 1 A medical method, comprising: positioning a cooling device in contact with tissue of a patient in a selected region of the patient's body that has a high density of cold sensitive thermoreceptors, wherein the cooling device includes a cold pack or a bandage assembly; and activating the cooling device to lower a temperature of the tissue in the selected region by a predetermined amount and for a predetermined treatment period that is sufficient to activate brown adipose tissue and increase energy expenditure of the brown adipose tissue, wherein the cooling device is activated in response to a trigger event including at least one of a change in the patient's tissue impedance and the patient falling asleep. ### Claim 2 (depends on 1) The method of claim 1, wherein positioning the cooling device in contact with tissue of the patient comprises positioning the device proximate to at least one of a wrist, an ankle, a hand palm, and a foot sole. ### Claim 3 (depends on 1) The method of claim 1, wherein the brown adipose tissue is at a supraclavicular region on one of a left and right side of a sagittal plane of the patient. ### Claim 4 (depends on 1) The method of claim 1, wherein positioning the cooling device in contact with tissue of the patient comprises transcutaneously applying the device to an exterior skin surface of the patient. ### Claim 5 (depends on 1) The method of claim 1, wherein the cooling is continuously delivered to the patient throughout the predetermined treatment period. ### Claim 6 (depends on 1) The method of claim 1, wherein the cooling device is configured to effect evaporative cooling. ### Claim 7 (depends on 1) The method of claim 1, wherein the cooling device effects cooling through one of inductive coupling, refrigeration, passive cooling, evaporation, topical cooling, heat exchange, and thermal transfer. ### Claim 8 (depends on 1) The method of claim 1, further comprising delivering at least one agonist to at least one thermal TRP channel using the cooling device. ### Claim 9 (depends on 8) The method of claim 8, wherein the at least one thermal TRP channel is one of TRPV1, TRPM8, and TRPA1. ### Claim 10 (depends on 1) The method of claim 1, further comprising removing the cooling device from the patient; repositioning the cooling device in contact with tissue of the patient in another region of the patient's body that has a high density of cold sensitive thermoreceptors; and activating the cooling device to lower a temperature of the tissue in the another region a predetermined amount and for a predetermined treatment period that is sufficient to activate brown adipose tissue and increase energy expenditure of the brown adipose tissue. ### Claim 11 (depends on 1) The method of claim 1, wherein the cooling device includes the bandage assembly, and the method further comprises removing thermal energy from the tissue using a cooling housing of the bandage assembly, and selectively turning the cooling housing on and turning the cooling housing off. ### Claim 12 (depends on 11) The method of claim 11, wherein the selective turning on and off is performed remotely from the patient. ### Claim 13 (depends on 1) The method of claim 1, wherein the predetermined treatment period is in a range of about 4 hours to about 12 hours. ### Claim 14 (depends on 1) The method of claim 1, wherein the cooling device delivers cold at a temperature in a range of about 4° C. to about 16° C. ### Claim 15 (depends on 1) The method of claim 1, further comprising: positioning a second cooling device in contact with a second tissue of the patient in a second selected region of the patient's body that has a high density of cold sensitive thermoreceptors, wherein the second coolies device includes a cold pack or a bandage assembly; and activating the second cooling device to lower a temperature of the second tissue in the second selected region to activate a second brown adipose tissue and increase energy expenditure of the second brown adipose tissue, wherein the second cooling device is activated in response to a second trigger event that is different from the trigger event, and the second trigger event includes a different one of the change in the patient's tissue impedance and the patient falling asleep. ### Claim 16 (depends on 1) The method of claim 1, wherein the cooling device includes the bandage assembly, and a controller causes the activation of the bandage assembly in response to a detection of the trigger event. ### Claim 17 (depends on 1) The method of claim 1, wherein the activation is causing the cooling device to start delivering cold to the patient. ### Claim 18 (depends on 1) The method of claim 1, wherein the trigger event also includes at least one of the patient eating, the patient resting, a threshold temperature of the patient, a directional orientation of the patient, and a blood chemistry change in the patient. ### Claim 19 (depends on 1) The method of claim 1, wherein the cooling device includes the cold pack.
