Disclosed herein is a medical device including: a positioning catheter to be inserted into a blood vessel in the vicinity of an affected region; a treatment catheter to be inserted to reach the affected region; and attracting means provided at respective predetermined positions of both the catheters to apply a magnetic force in a direction of attracting each other; wherein the magnetic force of the attracting means restricts floating of the treatment catheter.

Medical device and using method thereof

An energy irradiation device for medical use to irradiate a living body with energy includes a data storage for storing data indicative of correlations between information about bloodstream quantities and amounts of tissue necrosed in living bodies for a plurality of living bodies differing in bloodstream quantity that are irradiated with a predetermined quantity of the energy, a calculation unit for calculating a quantity of the energy with which to irradiate a predetermined living body based on the data stored in the data storage, the information about the bloodstream quantity in the predetermined living body, and the amount of tissue to be necrosed in the predetermined living body.

Energy irradiation device and method, control device and control method

A temperature measuring unit of a temperature sensor has electrodes disposed on the upper and lower surfaces of a temperature measuring element, thin-film substrates disposed on the upper and lower surfaces of the electrodes, and laser beam shield plates disposed on the upper and lower surfaces of the thin-film substrates. One of the electrodes is bonded to the temperature measuring element by a conductive adhesive, and the other electrode is not bonded to the temperature measuring element by a conductive adhesive. When the temperature sensor is bonded to a hollow cylinder of an insert, the temperature measuring unit is curved along the surface of the hollow cylinder, tending to develop tensile stresses in the other electrode. At this time, the other electrode is positionally displaced depending on the developed tensile stresses, allowing the temperature sensor to be adjusted in length. Consequently, the temperature sensor is prevented from being broken or damaged.

Medical energy irradiating apparatus

To make it possible to clean the internal part of a living body and possibly also deliver a drug into the living body, a medical therapeutic apparatus includes a liquid discharge for discharging a liquid in a living body out of the living body and a liquid delivery for introducing a liquid into the living body. The liquid is delivered to a target region of the living body, and controller controls the delivery and discharge of the liquid.

Medical therapeutic apparatus

A positioning system for an applicator includes a glove for being used for a diagnosis of the affected part, a mark body provided on the glove, an applicator for being inserted into a living body, and an energy emitter provided on the applicator for supplying energy to the living body. The positioning system further includes a sensor provided on the applicator which is capable of detecting the distance to the mark body, a control apparatus for discriminating an optimum position of the applicator based on the distance between the sensor and the mark body while the mark body is disposed in the proximity of the affected part based on a diagnosis performed using the glove, and a display apparatus for displaying a result of the discrimination by the control apparatus.
