Abstract: The present invention provides a method and apparatus for controlling the internal body temperature of a patient. According to the present invention, a catheter is inserted through an incision into a large blood vessel of a patient. By selectively heating or cooling a portion of the catheter lying within the blood vessel, heat may be transferred to or from blood flowing within the vessel and the patient's body temperature may thereby be increased or decreased as desired. The invention will find use in treating undesirable conditions of hypothermia and hyperthermia, or for inducing a condition of artificial hypothermia when desired.

The ablation needle and biopsy needle are adapted to in situ assembly with the delivery needle. In a preferred embodiment, the ablation needle, when engaged with the delivery needle forms a coaxial connector adapted to electrically couple to an ablating source. Methods for biopsying and ablating tumors using the device and coagulating the track upon device removal are also provided.

Abstract: A cryosurgical system comprises a compressor unit and a probe assembly. A secondary refrigerant stream from the compressor unit pre-cools a heat exchanger within the probe assembly in a standby mode of operation. After the heat exchange is pre-cooled, a primary refrigerant stream can be passed through the cooled heat exchanger and thereafter expanded within a tissue-contacting portion of the probe assembly to achieve very low temperatures, typically minus 100° C. or lower. After cooling, the refrigerant stream may be passed through the probe assembly with no or partial expansion to warm the tissue-contacting surface of the probe. A probe sheath can be used to provide sterility.

Abstract: An intravascular device for the formation of linear lesions which has particular utility in the treatment of atrial fibrillation and flutter.

Abstract: The present invention relates to an improved thermal conditioning apparatus for thermally treating a patient. More specifically, the present invention relates to an inflatable apparatus for bathing a patient with a thermally conditioned medium. Such a treatment apparatus is useful for medically treating a patient suffering from hypothermia or hyperthermia, or for maintaining the body temperature of a patient undergoing a surgical procedure.
