Julie Bu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: A catheter can restore the patency of a body lumen, for example, by removing tissue from a body lumen (e.g., a blood vessel). The catheter can be a rotational catheter having a rotatable drive shaft and a tissue-removing element secured to the drive shaft to be driven in rotation by the drive shaft. The catheter can have an abrasive burr configured to abrade tissue in a body lumen. The catheter can have an expandable tissue-removing element. The catheter can include a balloon and an inflation conduit. The catheter can also be configured to move over a guidewire through a body lumen. In one embodiment, the catheter comprises an over-the-wire, balloon-expandable, rotational, and abrasive tissue-removing catheter.
