Publication number: 20240074783Abstract: Rotational atherectomy devices and systems can remove or reduce stenotic lesions in implanted grafts by rotating one or more abrasive elements within the graft. The abrasive elements can be attached to a distal portion of an elongate flexible drive shaft that extends from a handle assembly that includes a driver for rotating the drive shaft. In particular implementations, individual abrasive elements are attached to the drive shaft at differing radial angles in comparison to each other (e.g., configured in a helical array). The centers of mass of the abrasive elements can define a path that fully or partially spirals around the drive shaft.Type: ApplicationFiled: October 17, 2023Publication date: March 7, 2024Inventors: Michael Kallok, Cassandra Ann Piippo Svendsen, Paul Joseph Robinson, Charles Anthony Plowe, Albert Selden Benjamin

Publication number: 20240065723Abstract: Rotational atherectomy devices and systems can remove or reduce stenotic lesions in blood vessels by rotating one or more abrasive elements within the vessel. The abrasive elements are attached to a distal portion of an elongate flexible drive shaft that extends from a handle assembly that includes a driver for rotating the drive shaft. In particular implementations, the handle assembly encapsulates an electric motor assembly, a pump assembly, and a controller assembly.Type: ApplicationFiled: October 24, 2023Publication date: February 29, 2024Inventors: Cassandra Ann Piippo Svendsen, Ryan D. Welty, Michael Kallok
