Abstract
A method of treating a tissue region (e.g., a tumor) is provided. The method comprises introducing a delivery sheath within an anatomical conduit that supplies the tissue region with a fluid (e.g., blood or air). The anatomical conduit may be any naturally occurring conduit within a patient. The method further comprises expanding an occlusive device (e.g., a balloon) associated with the delivery sheath, such that the conduit is at least partially occluded to reduce the flow of fluid through the conduit. The method further comprises introducing a tissue treatment catheter within the delivery sheath, advancing the treatment catheter from the delivery sheath through an aperture in a wall of the conduit adjacent the tissue region, and conveying thermal energy from (i.e., hyperthermia) or to the treatment catheter (i.e., hypothermia) to treat (e.g., by ablating) the tissue region.
