MEDICAL DEVICE WITH PRESSURE SENSOR

Pressure sensing guidewires and methods for making and using pressure sensing guidewires are disclosed. An example pressure sensing guidewire may include a tubular member having a proximal region anda housing region. An optical fiber may be disposed within the tubular member and extend to the housing region. The optical fiber may have a distal end region with a cavity formed therein. A polymericmember disposed within the cavity. A reflective surface disposed along the polymeric member. 公开了压力传感导丝以及用于制造和使用压力传感导丝的方法。示例性压力传感导丝可以包括管状构件，其具有近侧区域和壳体区域。光纤，其设置在管状构件内并且延伸到壳体区域。光纤具有空腔形成在其中的远端区域。设置在空腔内的聚合物构件。沿聚合物构件设置的反射面。
