Medical devices, systems, and methods for pain management and other applications may apply cooling with at least one probe inserted through an exposed skin surface of skin. The cooling may remodel one or more target tissues so as to effect a desired change in composition of the target tissue and/or a change in its behavior, often to interfere with transmission of pain signals along sensory nerves. Alternative embodiments may interfere with the function of motor nerves, the function of contractile muscles, and/or some other tissue included in the contractile function chain so as to inhibit muscle contraction and thereby alleviate associated pain. In some embodiments, other sources of pain such as components of the spine (optionally including herniated disks) may be treated.

A smart tourniquet includes a casing having a control unit; a contact area arranged to the casing, configured to contact a patient's skin, and connected to the control unit; a cuff arranged to the casing with an inflatable bladder; an adjustable strap arranged to the cuff for securing the cuff and casing to the patient; a pump contained in the casing, connected to the bladder, and controlled by the control unit; a thermoelectric module contained in the casing, controlled by the control unit, and connected to the contact area; and at least one sensor contained in the casing for detecting blood pulse and controlled by the control unit. The control unit is configured to inflate and deflate the bladder in response to blood pulse for changing a pressure around an arm or leg and to heat the contact area for vasodilating a vein under the patient's skin for visual detection.

The present device provides a method and an apparatus for applying a vaporized endothermic gas to a skin surface to provide numbing of the application site for injection with a syringe. The device includes a container or canister containing an endothermic gas that rapidly absorbs heat when released to the atmosphere. A depressible actuating member or trigger propels the gas or vapor through an outlet nozzle that is constructed to break the liquid into a vapor that can be projected as a stream of vapor along a delivery axis that intersects a delivery axis of the syringe needle; therefore, the gas or vapor can be successively delivered to an injection site with minimal repositioning of the device.

The present disclosure discloses and describes a vapocoolant dispenser. Specifically, the dispenser comprises a housing and container of vapocoolant, the dispenser configured to receive a sterilizable dose of high energy radiation and to provide a sterile, hermetically sealed vapocoolant dispenser.

A method in which a location is determined on the skin that is proximate to a sensory nerve that is associated with a painful condition. At least one needle of a cryogenic device is inserted into the location on the skin such that the needle is proximate to the sensory nerve. The device is activated such that the at least one needle creates a cooling zone about the sensory nerve, thereby eliminating or reducing severity of the painful condition.

An injection tool and associated methods are shown. Example tools and methods described provide cooling to numb a local area prior to an injection. The local numbing can be used to reduce or eliminate pain associated with the subsequent injection. In selected examples, circuitry and one or more sensors are used to calculate an appropriate contact time of a heat sink with the local region to best provide a desired amount of numbing.

A therapeutic burp cloth having at least one panel and at least one pocket. The therapeutic burp cloth is adapted to be worn by a caregiver while holding an infant. The pockets are adapted to receive heat pads, cold pads and therapeutic inserts for comforting the infant and the caregiver during use.

A cured liquid silicone rubber (“LSR”) body having an outer surface, an inner surface opposing the outer surface, a first end, a second end opposing the first end, a non-biased body length separating the first and second ends of the cured silicone body, a pre-formed pleated portion disposed circumferentially along the body length and operably configured to enable selective and elastically biased adjustment of the non-biased body length, non-pleated portions of the LSR body forming a smooth surface of the outer surface of the LSR body and flanking the pleated portion, forming a sleeve shape with at least one enclosed opening and a sleeve channel for receiving a user's limb and defined by the inner surface of the LSR body, and defining a plurality of perforations thereon, disposed on the non-pleated portions of the LSR body that span through the LSR body.

Disclosed is an applicator device for an apparatus used in a localized cryotherapy treatment. The applicator device is configured, when positioned over a body area to be treated, to receive and to uniformly distribute across the entire area covered thereby a stream of medium, such as air, adjusted to a temperature equal to or above −40 degrees Celsius (° C.) and directed, at a predetermined speed, via the applicator to the area to be treated, whereby a cold-induced thermal shock response is developed in skin and an underlying tissue within the area covered by the applicator. Related apparatus and a method are further provided.

A temperature regulating socket apparatus for selectively heating or cooling a residual limb of an amputee is provided. The temperature regulating socket apparatus includes a socket having a brim, a distal end and a continuous side wall, all defining an open interior area for receiving the residual limb therein and a temperature regulating apparatus. The temperature regulating apparatus includes a thermal adjustment element embedded within the socket side wall; a temperature control unit operatively coupled to the thermal adjustment element; and a power supply operatively coupled to the temperature control unit. When the power supply is in its ON orientation the temperature control unit is powered so that the temperature control unit regulates the temperature of the thermal adjustment element to selectively heat or cool the residual limb within the socket.
