  • Patent number: 5006111
    Abstract: A medical pump device is constructed so that a pulsation force is applied to the blood in the vicinity of an artery, which is reconstructed after a bypassing operation has been completed, so as to compensate for a deviation of an actual wave form of a blood flow in the vicinity of the reconstructed artery from a normal wave form thereof. The medical pump device is capable of minimizing the possibility of occurrence of a late obturation in an artery which is reconstructed after a reconstruction operation has been completed, and improving a rate of keeping open the reconstructed artery.

  • Patent number: 4676258
    Abstract: A device for radio-frequency hyperthermia havinga first electrode adapted to be disposed in a tract organ of a living body.A second electrode is provided which is adapted to be disposed on an outer circumference of the living body such that the second electrode is opposed to the first electrode such that there is generated a spatially inhomogeneous electric field within the living body in cooperation with the first electrode so that a part of the living body near the first electrode may be heated more strongly than a part of the living body near the second electrode.This serves to selectively heat a tumor or malignancy region at the deep inside of the living body by a noninvasive technique.

  • Patent number: 4662383
    Abstract: An endotract antenna used for hyperthermia treatments. A microwave radiation antenna is surrounded by a balloon-like member made of a thin polymeric film. Tubes for feeding and draining a cooling liquid to and from the inside of the balloon-like member enable the device to effectively warm an endotract lesion such as a tumor by effectively supplying the energy of the microwaves emitted from the antenna to the endotract lesion.
