Patent number: 11931062Abstract: 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, 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 spirals around the drive shaft in a direction that is opposite to the wind direction of filars of the drive shaft, and opposite to the direction of rotation. In some embodiments, a concentric abrasive tip member is affixed to and extends distally from a distal-most end of the drive shaft.Type: GrantFiled: November 23, 2021Date of Patent: March 19, 2024Assignee: Cardio Flow, Inc.Inventors: Paul Joseph Robinson, Cassandra Ann Piippo Svendsen, Albert Selden Benjamin, Charles Anthony Plowe

Patent number: 11931275Abstract: A convertible nephroureteral catheter is used in the treatment of urinary system complications, particularly on the need for a single surgically delivered device to treat patients who must be seen by an interventional radiologist (IR). In many current procedures, patients need to return to the operating room to remove a previously delivered nephroureteral catheter to exchange this catheter with a fully implanted ureteral stent delivered though the same access site at the flank. The present convertible nephroureteral catheter reduces the need to return for a second surgical procedure. Two weeks after initial implantation, the proximal portion of the convertible nephroureteral catheter extending out from the body may simply be removed. A simple action at the catheter hub allows this proximal portion to be removed, leaving behind the implanted ureteral stent within the patient's urinary system. Other medical procedures, devices, and technologies may benefit from the described convertible catheter.Type: GrantFiled: July 23, 2020Date of Patent: March 19, 2024Assignee: Merit Medical Systems, Inc.Inventors: Harry R. Smouse, Kent C. B. Stalker, Timothy H. Williams, Eugene R. Serina
