Abrégé

Cooling systems are described herein that may be used in connection with one or more attached devices to cool patient tissue. The disclosed cooling systems include a refrigeration unit containing a thermoelectric element in thermal communication with a heat exchanger, a fluid pump in fluid communication with a fluid inlet and a fluid outlet, tubing connecting the fluid inlet to the fluid outlet, a fluid cooling element in thermal contact with the thermoelectric element, and a temperature sensor positioned to detect a temperature of fluid within the tubing. The temperature of fluid within the tubing can be controlled by a control unit having a user interface and a power controller to adjust cooling power to the thermoelectric element. Various types of devices can be configured to receive and circulate cooled fluid from the cooling systems, such as retractor blades, retractor shims, cooling pads, and scope sheaths.

Methods and devices are disclosed herein that generally involve cooling tissue (e.g., localized cooling of tissue), and in particular applying therapeutic hypothermia to the spinal canal, tissue disposed within the spinal canal, and/or nerve roots extending from the spinal canal. In some embodiments, tissue can be cooled by clamping a cooling instrument to a bone or implant that is proximate to the tissue. The cooling instrument can define a chamber through which a chilled fluid, expandable gas, or other coolant means can be circulated, delivered, or activated to cool adjacent tissue. The degree of cooling can be regulated using a controller, which can be configured to increase or decrease the cooling effect based on any of a variety of measured or predicted physiological or thermodynamic properties. Methods are disclosed for utilizing cooling instruments and for carrying out various treatment regimens that involve cooling tissue using such instruments.
