A heat exchanger is disclosed for causing cryolysis of adipose tissue of a human tongue. The heat exchanger includes a body having cooling channels for circulating fluids therein. The body forms a contact surface that contacts a portion of the dorsal surface of the tongue and a portion of the base of the tongue. The heat exchanger includes a pair of side walls extending from the body and forming a pair of side contact surfaces that are dimensioned so that they contact the dorsal and lateral surfaces of the tongue in a manner so as to constrict the tongue when the contact surface is in contact with the tongue. A method of treatment for apnea using the heat exchanger and/or administering a chemical adipolysis formulation/vasoconstriction agent is also disclosed.

A treatment system includes a generator and a fluid transfer cartridge. The fluid transfer cartridge includes a cartridge shell defining a cartridge cavity between a front face and a rear face. The front face includes an opening, and the cartridge cavity is visibly exposed through the opening. The fluid transfer cartridge includes a syringe barrel disposed within the cartridge cavity, and a handle that extends from the front face over the opening. The syringe barrel can be visibly exposed on a side of the handle. Other embodiments are also described and claimed.

Relatively non-invasive devices and methods for heating or cooling a patient's body are disclosed. Devices and methods for treating ischemic conditions by inducing therapeutic hypothermia are disclosed. Devices and methods for inducing therapeutic hypothermia through esophageal cooling are disclosed. Devices and methods for operative temperature management are disclosed.

Embodiments include a cryogenic device for alleviating pain by cryogenically treating a nerve, the cryogenic device including a handpiece; a needle coupled to a distal end of the handpiece, the needle including a needle lumen, the needle being configured for insertion into a skin of a patient along an insertion axis at a site laterally displaced from a treatment zone proximate to the nerve. The needle is configured to resiliently bend after insertion away from the insertion axis, such that at least a portion of the needle is adapted to traverse a skin layer laterally toward the treatment zone. The device includes a cooling fluid supply tube extending distally into the needle lumen; and a cooling fluid source, wherein the cooling fluid source is coupled to the cooling fluid supply tube to direct cooling fluid into the needle lumen.

Devices, systems, and methods for applying pulsed energy to effectuate a physiological response in a human subject. Systems and methods disclosed herein can include, for example, a stimulus device that applies pulsed energy, such as heat, into a volume of tissue. The stimulus device can include one or more electrodes and can be affixed to the skin or implanted at a target site within the body. The systems and method can further include a monitoring device that detects at least one physiological parameter of the human subject during application of the pulsed energy, such as blood flow, oxygen delivery, muscle tension, subcutaneous or muscle temperatures, or brain activity. A control device can use the detected physiological parameter to define treatment parameters of the stimulus device such that the pulsed energy synchronizes with the measured physiological parameter to effectuate a desired response, such as reducing pain, suppressing appetite, and/or activating a hedonic response.

An intravenous heat exchange catheter and/or an external cooling pad/bladder can be used to maintain hypothermia in, e.g., a cardiac arrest patient, but to accelerate the cooling process the patient first can be infused with cold saline before the opportunity arises to connect the catheter or pad to the patient.
