Publication number: 20240009387Abstract: An infusion pump, including a housing, a user interface, a motor and a set of drive components, and a controller. The housing enables selective stacked attachment with other infusion pumps. The housing includes a top portion with a handle integrated into an outer surface that partially defines a generally U-shaped retaining feature. The housing also includes a bottom portion with a generally U-shaped projection that is contoured to selectively mate with the retaining feature of another infusion pump. The user interface provides a front side to the housing that receives commands regarding infusion pump operation. The motor and set of drive components are at least partially located within the housing and mechanically direct infusion of infusate. The controller is located within the housing and that controls operation of the motor and the set of drive components.Type: ApplicationFiled: September 22, 2023Publication date: January 11, 2024Inventors: Christopher Allen Lacy, Grant A. Adams, Steven Plager, Kevin Krautbauer, Jonathan Sanborn, Manfred Maiers, Walter Dobrovolny, Eric Wilkowske

Patent number: 8628551Abstract: The invention provides a rotational atherectomy system, device and method comprising a flexible, elongated, rotatable drive shaft with an abrasive section within a pre-curved section of the drive shaft. The device may further comprise a concentric or eccentric enlarged diameter section that is at least partially covered with abrasive material to comprise the abrasive section. The abrasive section may further comprise an abrasive crown or burr mounted to the drive shaft. The pre-curved drive shaft allows smaller diameter and/or massive abrasive regions to be used while sweeping larger diameters during high-speed rotation. The pre-curved region is substantially straightened for insertion into vasculature and placement adjacent stenosis by insertion of the guide wire. Removal of guide wire proximally from the pre-curved region allows the drive shaft to return to its pre-curved form for ablation. Reinsertion of the guide wire beyond the pre-curved region straightens the drive shaft for ease of removal.Type: GrantFiled: October 13, 2009Date of Patent: January 14, 2014Assignee: Cardiovascular Systems, Inc.Inventors: Scott M. Hanson, Walter Dobrovolny, Jeffrey R. Stone
