    Abstract: 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.

    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 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). The centers of mass of the abrasive elements can define a path that fully or partially spirals around 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, the handle assembly encapsulates an electric motor assembly, a pump assembly, and a controller assembly.

    Abstract: A rotational atherectomy device for removing a stenotic tissue from the iliac artery of a patient. The device comprises a flexible, rotatable drive shaft having an elongated proximal portion, an elongated distal portion. An abrasive element is mounted to the drive shaft between the elongated proximal and distal portions of the drive shad and between and spaced away from a pair of counterweights which are mounted to said elongated portions of the drive shaft. The eccentric abrasive element and the counterweights are configured for rapid rotation together with the drive shaft, the drive shaft is configured to extend throughout an entire length of the iliac artery to be treated. One elongated portion of the drive shaft extends out of the patient through a first access opening located in a femoral artery which is ipsilateral to the treated artery. Another elongated portion of the drive shaft extending through a second access opening located in another peripheral artery of the patient. A method of treating are iliac artery of a patient using such a rotational atherectomy device.

    Abstract: A rotational atherectomy device for removing a stenotic tissue from a vessel of a patient comprises a flexible hollow drive shaft and an abrasive element mounted to the drive shaft proximal to and spaced from a solid support element mounted at the distal end of the drive shaft, the solid support element having a rounded outer surface and an outflow channel with an outflow opening in said rounded outer surface. The drive shaft comprises a torque transmitting coil and at least one fluid impermeable membrane forming a fluid impermeable lumen for the antegrade flow of fluid into the outflow channel such that, during rotation of the drive shaft, a flow of fluid out of said outflow opening forms a fluid bearing between the rotating solid support element and the wall of the treated vessel.
