一种植入式心内血压监测传感器
By designing an implantable intracardiac blood pressure monitoring sensor, employing a support shaft, pressure-sensitive chip, and high-elasticity memory alloy stent structure, the problem of existing heart failure monitoring methods being unable to achieve long-term continuous and accurate monitoring has been solved. This enables real-time and accurate monitoring of intracardiac blood pressure, reduces the risk of sensor displacement and complications, and is suitable for the management of patients with chronic heart failure.

AI Technical Summary
Existing heart failure monitoring methods cannot achieve long-term, continuous, and accurate monitoring of left atrial pressure. Conventional methods are not real-time and involve invasive examinations with high risks, while non-invasive techniques are not mature enough to meet the daily management needs of patients with chronic heart failure.
An implantable intracardiac blood pressure monitoring sensor was designed, which adopts a support shaft, pressure-sensitive chip, inductor coil and high-elasticity memory alloy stent structure, combined with flexible materials and fixation hooks to achieve minimally invasive delivery, precise positioning and long-term stable monitoring. The stent is composed of multiple high-elasticity memory alloy strips arranged around the support shaft to form a three-dimensional arch structure that fits the inner wall of the left atrium and has adaptive deformation capability.
It enables real-time and accurate monitoring of intracardiac blood pressure, reduces the risk of sensor displacement and detachment, improves the stability and biocompatibility of signal transmission, reduces the risk of complications, and is suitable for long-term management of patients with chronic heart failure.
