    摘要： An atherectomy device is disclosed, with a clutch between the motor and the drive shaft. The clutch includes two plates that rely on frictional to transmit torque from one plate to the other. The clutch has an attractive magnetic normal force that holds the plates together. For relatively low torques, as is the case during normal use, a static frictional torque holds the plates together, and the plates spin together without slipping. For relatively high torques, as occurs when the distal end of the drive shaft encounters an obstacle and stops abruptly, the high torque exceeds the maximum possible static frictional torque, and the plates slip. When slipping, the plates transmit a kinetic frictional torque that is low enough to avoid damage to the patient or to the atherectomy device. In some cases, the torque levels associated with a stoppage of the drive shaft distal end are chosen to mimic those of a known atherectomy device, in which a gas-driven turbine is clutchlessly attached to the drive shaft.

    摘要： The invention provides a system, device and method for localized application of therapeutic substances within a biological conduit after the lumen wall has been scored by an eccentric scoring head. One embodiment comprises radial scoring with the eccentric scoring head, with a therapeutic agent coated balloon inflated distal to the scoring and dragged proximally through the scoring. Another embodiment comprises inflation of two anchor balloons on either side of scoring with subsequent inflation of a therapeutic agent coated balloon therebetween which causes the distance between anchor balloons to increase, thus stretching the scoring crevices while applying the agent therein with subsequent closure of crevices on deflation of anchor and application balloons. Another embodiment comprises an inflated anchor balloon with a threaded scoring device wherein the scoring members are coated with agent and rotation of the threaded device enables travel in the proximal direction away from anchor balloon.

    摘要： 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.
