Patent number: 9220529Abstract: An atherectomy device is disclosed, which is rotationally driven by an electric motor. In some designs, the device includes features unavailable on gas turbine-driven systems, such as the storing in memory of low/medium/high preset rotation speeds for particular models of handle, calculations of the amount of saline left in the IV and associated warnings when it gets sufficiently low, and automatic adjustment of the IV pump rate to a predetermined or calculated level when the rotational speed of the motor is changed. The electric motor has far more rotational inertia than a comparable gas turbine, so the system includes a control mechanism that helps prevent damage from excessive torque being applied to the distal end of the drive shaft. When an obstruction at the distal end is detected, by a drop in the motor rotational speed, the motor is released and is allowed to spin freely as a flywheel.Type: GrantFiled: September 21, 2012Date of Patent: December 29, 2015Assignee: Cardiovascular Systems, Inc.Inventors: Jody Lee Rivers, Charles A. Plowe, Cassandra Ann Piippo Svendsen, Walter John Dobrovolny, Michael John Eng, Scott M. Hanson

Patent number: 8551130Abstract: The invention provides a system, device and method for localized application of therapeutic substances within a biological conduit. One embodiment comprises a rotational atherectomy device having a flexible, elongated, rotatable, drive shaft having a lumen and with an eccentric enlarged abrading head having at least one application hole attached therethrough and in communication with a therapeutic agent delivery sheath and an operator-controlled actuator. The therapeutic substances may then spray radially outwardly from the application hole(s) on the eccentric abrading head during and/or after high-speed rotation of the head. Another embodiment comprises compartments in the abrading head that hold therapeutic agent(s) for release during high-speed rotation. In each case, the therapeutic substance(s) is delivered with radial forces resulting from high-speed orbital rotation of the eccentric abrading head, driving the therapeutic substance(s) into the conduit wall.Type: GrantFiled: February 15, 2011Date of Patent: October 8, 2013Assignee: Cardiovascular Systems, Inc.Inventors: Victor Leo Schoenle, Jody Lee Rivers, Jesse C.
