Abstract: This document describes rotational atherectomy devices and systems for removing or reducing stenotic lesions in blood vessels by rotating an abrasive element within the vessel to partially or completely remove the stenotic lesion material.

Abstract: 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 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. In some embodiments, a distal stability element with a center of mass aligned with the longitudinal axis is fixedly mounted to the drive shaft.

Abstract: 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.

Abstract: In an example, a transformer can include a core that can include a composite material and have a first permeability. The transformer can further include a primary coil that can be wound about the core. The primary coil can be configured to vary a primary magnetic energy into the core based on a primary current.

The transformer can further include an outer return that can include a laminate material and have a second permeability. The second permeability can be greater than the first permeability. The outer return can provide a magnetic-return path for magnetic energy from a first end of the core to a second end of the core.

Abstract: A dental prophylaxis angle having a tool head and a hand piece includes an adjustment mechanism, which allows the tool head to be angularly adjusted between a plurality of angular positions relative to the hand piece. The tool head is axially shiftable relative to the hand piece between a locked position and an adjustment position. In the locked position, the tool head is prevented from shifting angularly relative to the hand piece. In the adjustment position, the tool head may be selectively pivoted relative to the hand piece and thereby angularly adjusted. A spring may be provided to urge the tool head into the locked position at one or more of the angular positions.
