SENSOR DEVICE AND METHODS OF OPERATION FOR CATHETER BASED TREATMENT OF MYOCARDIAL MICROVASCULAR OBSTRUCTION

Provided herein are sensor devices and methods of operation for catheter-based microvascular microvascular occlusion treatment by injecting a fluid having a protective agent into the vasculature. Thecatheter device (100) may include a first lumen (3) configured for advancement over a guide wire and for passage of fluid having protective agents after removal of the guide wire and a second lumen (2') for inflation of an angioplasty balloon (7) and can further include a temperature and/or pressure sensor (10) mounted on the catheter body. Such a catheter device (100) can further include use of adistal occlusive membrane (8) between the angioplasty balloon and a distal end to facilitate infusion into microvasculature. The occlusive membrane (8) can be deployed by relative movement of concentric channels (4, 6), thereby reducing the need for an additional lumen while optimizing the size of the catheter device and lumens. 本文提供了传感器装置和操作方法，用于通过将具有保护剂的流体注入脉管系统来进行基于导管的微脉管微血管阻塞治疗。这种导管装置(100)可以包括第一内腔(3)以及第二内腔(2')，该第一内腔被配
