FIELD: medicine. n SUBSTANCE: group of inventions relates to medical equipment. Intravascular device for sensor delivery contains distal sleeve, sensor and proximal part. Distal sleeve has opening for reception of a separate medical wire guide and sliding along it. Sensor measures patient's physiological parameter and generates a signal used, for calculation of fraction reserve of blood flow. Proximal section has main section and distal transitional section, connecting main section with external surface of distal sleeve. Proximal section contains a channel of connection for transmission of signal from sensor into location outside patient and facilitates positioning of sensor in anatomical structure of patient. Intravascular device for sensor delivery can contain multi-opening rod with openings for wire guide and for sensor, and two sensors, first of which is connected with sensor rod and second - with external section of multi-opening rod. Sensors can be placed at a variable distance from each other due to sliding of sensor rod relative to multi-opening rod. System of flowing medium injection contains tube for flowing medium supply, control panel and processor, which can receive signal, presenting information about blood pressure, from device for sensor delivery. n EFFECT: application of the claimed group of inventions will make it possible to increase accuracy of device positioning. n 15 cl, 17 dwg |
