MICROCATHETER SENSOR DESIGN FOR MINIMIZING PROFILE AND IMPACT OF WIRE STRAIN ON SENSOR

摘要

Conduit, such as blood flow reserve conduit, the elongated shaft that including elongated shaft there is pressure sensing line to extend to distal portion. Wire has a pressure sensor, the container of the pressure lumen for measuring the fluid in distally mounted. The conduit that pocket is formed in the neighbouring pressure sensor smallest cross sectional is arranged in pressure sensor line. It is subjected to bending stress, when being mounted on blood flow reserve tracking conduit by pressure sensor, conduit is deformed by vascular system, leads to the pressure reading or bending error of incorrect sensor. In sequence from bending stress, with isolation sensor, sensor distance is opened to allow pressure sensor, and the lead of pressure sensor is independently moved with pressure sensor conducting wire to be separated from each other.
