Abstract:
PROBLEM TO BE SOLVED: To provide a coating for implantable electrode consisting of a single- or multi-walled nanotube, a nanotube rope, a carbon whisker, and a combination of these. SOLUTION: The nanotube may be carbon or other conductive nanotube-forming material such as carbon-doped boron nitride. The nanotube coating is grown in situ on the surface of a catalyst substrate by the thermal decomposition, or is applied to the substrate using a thin film binder of a vapor-deposited metal using a metal compound precursor in liquid form or a conductive metal oxide. In the case of using the precursor, the coating of the precursor/nanotube is converted to a pure metal or conductive metal oxide thereafter, resulting in the desired surface coating in which the nanotube is embedded.

Abstract:
PROBLEM TO BE SOLVED: To provide pyrotherapeutic equipment capable of performing stable pyrotherapeutic treatment by reducing the error of the pyrogenic temperature between pyrogenic parts due to the difference of initial setting between the pyrogenic parts. SOLUTION: The pyrotherapeutic equipment 1 is constituted of a coagulating/incising forceps 2 having a plurality of pyrogenic elements 21 built therein and the equipment main body 3. The forceps discrimination part 31 in the main body 3 confirms the discrimination between the kinds of the forceps of the discriminator 10 and the data of the individual pyrogenic elements 21 to impart them to a temperature control and correction part 32. The temperature control and correction part 32 reads control resistance values necessary for the individual set temperatures of the respective pyrogenic elements 21 from a memory 40 on the basis of that data. A generation-of-heat setting part 33 sets the control resistance value of a set temperature level from the control resistance values. A resistance value detecting part 35 calculates the resistance values of the pyrogenic elements 21 from the measured result by an applied power detecting part 34 and an output power control part 36 performs the output control of the power to the pyrogenic elements 21 so that the calculated resistance values are held to the resistance value set in the generation-of-heat setting part 33.

Abstract:
PROBLEM TO BE SOLVED: To provide a system which determines an effective fibrillation energy released into an implanting fibrillation system without the repeated induction of the fibrillation in the heart of a patient. SOLUTION: The system herein disclosed determines the defibrillation threshold energy in the defibrillation induction structure by applying shocks to the heart until the heart undergoes the fibrillation state while lowering the energy level during the T wave period in the electrocardiogram. The lowest energy level of those examined that fail to make the heart undergo the fibrillation state is mutually related to the defibrillation threshold energy in the induction structure.
