Bavaria Medical Technology, Canada Inc. is developing the CutCath, a percutaneous site preparation device used to cut through calcified heart valve leaflets in order to enhance the apposition of prosthetic valves. However, by combining the cutting element in the CutCath with ultrasound, the energy requirement may be lowered. It is hypothesized that using these vibrations would help cut through a densely calcified valve without applying great strain on the heart.

Bavaria Medical Technology，Canada Inc.正在开发CutCath，这是一种经皮部位准备器械，用于切开钙化的心脏瓣膜小叶，以增强人工瓣膜的贴壁。然而，通过将CutCath中的切割元件与超声结合，可以降低能量需求。据推测，使用这些振动将有助于切割密集钙化的瓣膜，而不会对心脏施加很大的压力。
