    摘要: Apparatus and methods for cooling selected regions within a body are described herein. An implantable cooling system is used to cool regions of the brain, spinal cord, fibrous nerve bodies, e.g., vagus nerve, etc. down to about 30° C. to diminish nerve impulses which control seizures or chronic pain. The system includes an implantable unit containing a pumping mechanism and/or various control electronics. It also has a heat exchanger attachable to a tubular body organ, such as the superior vena cava or the inferior vena cava, through which the heat is effectively dissipated. Also included is a heat pump such as a Peltier junction configured to be placed into contact with the region of tissue to be cooled. The heated portion of the Peltier junction is cooled by a liquid heat transfer medium which absorbs the heat from the junction and dissipates it into the tubular body organ.

    摘要: This invention is a device (10) for releasing a therapeutic appliance, such as an embolic coil (12) inside an aneurysm (16). The device includes a coupling (24) of a shape memory alloy which is responsive to a change in temperature beyond a predetermined transformation point so as to change the shape of the coupling from a first configuration, wherein the coupling receives and holds the proximal end (72) of the coil, to a second configuration wherein the coil can be released from the coupling. An energy receiver (46) is operably associated with the coupling to heat the coupling to a temperature above the transformation point with laser or electrical energy received from an external source.
