Disclosed is a system which employs a cooling or heating pad which is preferably rechargeable with hot or cold temperatures at an intended area of the body. The pad includes a highly temperature-conductive or temperature-retentive material which can be cooled or heated using a portable source of heat or cold material delivered to the pad by a removable delivery conduit. Valves can be included to regulate flow of the cooling or heating material from the source to the pad. The system can also include a dual-chambered canister for containing two different media for heating, cooling or for alternating heating and cooling the pad.

An intravascular catheter site pad is provided for thermal exchange (e.g. cooling) adjacent to a catheter introduction site (e.g. a catheter for the administration of a chemotherapeutic agent). The pad includes an opening defined by an opening edge that may be positioned about the catheter introduction site. The pad may further include a fluid containing layer and an inlet port and an outlet port for circulating fluid (e.g. cooled fluid) through the pad. The pad may be fluidly interconnected to a fluid conditioning unit to circulate fluid through the pad under negative pressure. The pad, system and an associated method may be employed to reduce tissue damage at an IV catheter introduction site.

Prosthetic liners, prosthetic sockets and prosthetic suspension sleeves, as well as orthotic components, having enhanced thermally conductivity and/or enhanced heat absorption capabilities. Such components may be used in various combinations to create assemblies and systems that are operative to better transfer heat away from and/or absorb heat produced by residual or intact limbs of a user.

Disclosed herein is a system, apparatus and method directed to an expandable and conformable targeted temperature management (TTM) pad. The system, apparatus and method pertain to a medical pad for exchanging thermal energy between a TTM fluid and a patient. The pad includes an insulating layer, a fluid containing layer for containing the TTM fluid, and a patient contact surface. The fluid containing layer is configured for circulating the TTM fluid. The patient contact surface defines a first patient contact area to facilitate thermal energy exchange with the patient. One or more slits are arranged in at least the insulating layer of the pad to facilitate stretching the pad and conforming to a contour of a patient's anatomy. The stretching can expand the patient contact surface to a larger second patient contact area. The pad can further include a flexible fabric cover.
