Question:

How does the Cavitron Ultrasonic Surgical Aspirator work?

Answer:

To my knowledge, there are no applications of the Cavitron Ultrasonic Surgical Aspirator relevant to stroke. Thus, this question is outside the scope of my expertise. However, a quick literature search shows that this is a device that surgeons can use to remove masses (tumors), especially those that are fibrous. My assumption is that the ultrasound energy emitted by this device help disrupt/break up the tumor, and then the fragments can be aspirated (sucked out). I hope this helps. You might try to redirect your question to another specialty area relevant to surgery.
