Uniform selective cerebral hypothermia
InactiveUS20030130651A1Surgical instrument detailsIntravenous devicesCooling chamberTemperature difference
Disclosed is an apparatus and method for uniform selective cerebral hypothermia. The apparatus includes a brain-cooling probe, a head-cooling cap, a body-heating device and a control console. The brain-cooling probe cools the cerebrospinal fluid within one or more brain ventricles. The brain-cooling probe withdraws a small amount of cerebrospinal fluid from a ventricle into a cooling chamber located ex-vivo in close proximity to the head. After the cerebrospinal fluid is cooled it is then reintroduced back into the ventricle. This process is repeated in a cyclical or continuous manner. The head-cooling cap cools the cranium and therefore cools surface of the brain. The combination of ventricle cooling and cranium cooling provides for whole brain cooling while minimizing temperature gradients within the brain. The body-heating device replaces heat removed from the body by the brain-cooling probe and the head-cooling cap and provides for a temperature difference between the brain and the body where the brain is maintained a temperature lower than the temperature of the body.

Disclosed is an apparatus and method for reducing secondary brain injury. The apparatus includes a brain-cooling probe and a control console. The brain-cooling probe cools the brain to prevent secondary injury by cooling the cerebrospinal fluid within one or more brain ventricles. The brain-cooling probe withdraws a small amount of cerebrospinal fluid from a ventricle into a cooling chamber located ex-vivo in close proximity to the head. After the cerebrospinal fluid is cooled it is then reintroduced back into the ventricle. This process is repeated in a cyclical or continuous manner in order to achieve and maintain a predetermined brain ventricle temperature lower than normal body temperature. The apparatus and method disclosed provides effective brain ventricle cooling without the need to introduce extra-corporeal fluids into the brain.

Device to reduce brain edema by surface dialysis and cooling
We have developed a novel method of brain surface dialysis that reduces intracranial pressure and modifies movement of extracellular fluid in a rat model of brain injury. A chamber with a semipermeable membrane at the site of brain contact is perfused with a hyperosmolar solution (e.g. 15% dextran, inulin, hydroxyethyl starch). It is also capable of providing local brain cooling. In principle, osmotic forces draw water and small molecules from the injured brain into the dialysis chamber thereby reducing brain swelling. The dialysate does not move into the brain.

The present invention is directed to a scarf having a sealable pocket. Within the pocket is a Joule-Thompson gas chamber having an activation device. When the activation device is triggered, the compressed gas is released from the Joule-Thompson gas chamber through at least one restriction aperture into the sealable pocket. That release results in at least the walls of the sealed pocket being cooled. Prior to being cooled or after being cooled, the scarf is placed over a portion of the patient's body. Preferably, the scarf is positioned over at least one of the patient's carotid arteries, preferably both, to effectively cool the patient's brain and / or body core temperature.
