Systems and methods for remote thermographic assessment of tissue viability are disclosed. A system may include a controllable source of one or more thermal stimuli to be applied to a tissue, a measurement system to measure a heat response of the tissue before, during, and/or after the application of the thermal stimuli, and an electronic device that may control either one or both of the source of thermal stimuli and the measurement system. The electronic device may also receive tissue thermal response data from the measurement system, and may further calculate a measure of tissue viability. A method of determining tissue viability may include supplying a thermal stimulus to a tissue, receiving, by a measurement device, the thermal response of the tissue to the stimuli, and a comparison of the thermal response data to at least some viability threshold values. The results may be displayed in a graphical manner.

Devices for non-contact thermographic mapping of tissue for viability assessment and methods of their use

Apparatus for altering the body temperature of a patient comprises a cover for covering at least a portion of a patient's body and a compliant support adapted to underlie and generally conform to the shape of the portion of the patient's body to define a well adjacent to the patient's body portion for accumulating heat transfer liquid. The cover and compliant support cooperatively define an enclosure for receiving the portion of the patient's body and are constructed to conduct a heat transfer liquid into direct contact with the portion of the patient's body received in the enclosure to promote heat transfer between the patient's body and the heat transfer liquid.

Apparatus for altering the body temperature of a patient

Apparatus for altering the body temperature of a patient comprises an enclosure defining an interior space for receiving at least a portion of a patient's body therein. The enclosure is constructed for transferring a heat transfer liquid into direct contact with the portion of the patient's body received in the enclosure to promote heat transfer between the patient's body and the heat transfer liquid. A drain for draining the heat transfer liquid from the interior space of the enclosure is at least partially disposed beneath the enclosure. A hold-open inhibits occlusion of the drain. A weir in fluid communication with the drain maintains the heat transfer liquid at a predetermined height in the enclosure. A control system is preprogrammed with a target temperature for the body temperature of the patient.

Apparatus for altering the body temperature of a patient includes an enclosure defining an interior space for receiving at least a portion of a patient's body therein. The enclosure is constructed to conduct a heat transfer liquid into direct contact with the portion of the patient's body received in the interior space to promote heat transfer between the patient's body and the heat transfer liquid. A reservoir for holding a supply of heat transfer liquid is disposed on the enclosure.

Apparatus for altering the body temperature of a patient comprises an enclosure defining an interior space for receiving at least a portion of a patient's body therein. The enclosure has at least one gusset that is resiliently deformable for accommodating patients of various sizes. A supply conduit fluidly connects an inlet of the enclosure to a reservoir, and a return conduit fluidly connects an outlet of the enclosure to the reservoir. A first coupler joins the supply conduit and the return conduit to the reservoir and a second coupler joins the supply conduit and the return conduit to the enclosure. The reservoir generally comprises a bag and at least a portion of the supply conduit is integral with the bag.

Apparatus for altering the body temperature of a patient comprises an inflatable mattress defining an interior space for receiving at least a portion of a patient's body therein. The inflatable mattress is constructed to conduct a heat transfer liquid into direct contact with the portion of the patient's body. The inflatable mattress includes a first zone inflatable to a first pressure and a second zone inflatable to a second pressure greater than the first air pressure. The inflatable mattress in an inflated condition defines a well for receiving the portion of the patient therein. A head positioner positions the patient's head so that the patient's breathing passageway remains out of contact with the heat transfer fluid. A method of adjusting the body temperature of a patient comprises filling the first and second zones, positioning the portion of the patient's body on the mattress, and directing the heat transfer liquid to contact the patient's body.

An apparatus for adjusting the body temperature of a patient comprises an enclosure defining an interior space for receiving at least a portion of a patient's body therein. The enclosure is adapted for substantially sealingly enclosing the portion of the patient's body within the interior space with the enclosure. Heat transfer liquid may then be circulated through the interior space of the enclosure via an inlet and an outlet for flow over the patient's body in direct liquid contact therewith to promote heat transfer between the patient's body and said heat transfer liquid. The heat transfer liquid may be either warmer or cooler than the patient's body temperature, to either warm or cool the portion. Controlled cooling may be employed to induce therapeutic hypothermia, while controlled warming may be employed to counteract unintended hypothermia. The apparatus further comprises a portable control unit that includes a liquid delivery system, a power source, a control system and a user interface for powering and controlling the liquid delivery system.

A balloon catheter has a balloon membrane, a tip connected to the distal end of the balloon membrane and an outer tube connected to the proximal end of the balloon membrane for supplying a medium for inflating and deflating the balloon membrane. A pressure sensor, such as a fiber optic sensor, may be mounted in a pocket in the tip. The pocket may be filled with a flexible substance which both communicates pressure to and protects the pressure sensor. A membrane may overlie the pocket to prevent leakage of the flexible substance therefrom.
