    摘要： Rotational atherectomy devices and systems can remove or reduce stenotic lesions in blood vessels by rotating an abrasive element within the vessel. The abrasive element can be attached to a distal portion of an elongate flexible drive shaft that extends from a handle assembly. In particular embodiments, the handle assembly includes a compressed gas driven turbine member that drives rotation of the drive shaft. The turbine member can be rotatably attached to a carriage that is longitudinally translatable in relation to a housing of the handle assembly. The handle assembly can include a latch mechanism that when actuated allows the carriage to translate to a proximal-most position. While the carriage is in the proximal-most position, an open pathway is created so that a guidewire can be slidably passed through the handle assembly and a lumen of the drive shaft.

    摘要： 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.

    摘要： 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).

    摘要： 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.
