    摘要： A rotational atherectomy system is disclosed, comprising: an elongated, flexible spin-to-open drive shaft having a distal end for insertion into a vasculature of a patient and having a proximal end opposite the distal end remaining outside the vasculature of the patient; a concentric or eccentric abrasive element, preferably a solid crown, attached to the drive shaft proximate the distal end of the drive shaft; an electric motor rotatably coupled to the proximal end of the drive shaft, the electric motor being capable of rotating the drive shaft in a spin-to-open direction; and control electronics for monitoring and controlling the rotation of the electric motor. When an obstruction at the distal end is detected by the applied torque and/or current reaching a predetermined maximum allowed level and with the drive shaft opened to a maximum allowed outer diameter, power to the motor is eliminated.

    摘要： Devices including, but not limited to, a self-expandable member having a proximal end portion and a main body portion. The self-expandable member is movable from a first delivery position to a second placement position, in the first delivery position the expandable member being in an unexpanded position and having a nominal first diameter and in the second position the expandable member being in a radially expanded position and having a second nominal diameter greater than the first nominal diameter for deployment within a vessel or duct of a patient. The expandable member includes a plurality of cell structures with the cell structures in the main body portion extending circumferentially around a longitudinal axis of the expandable member and the cell structures in the proximal end portion extending less than circumferentially around the longitudinal axis of the expandable member.

    摘要： This is a surgical device usually delivered through an intravascular catheter. It may be used in several ways. It may, for instance, be used to open a clear passageway adjacent thrombus to allow both blood and medication to bypass the clot. It may be used to pierce and to remove thrombus. These thrombus are often found in tortuous vasculature. The device includes several sections. The device has a core element, typically a core wire. Placed around the distal end of the core element is a collapsible but preferably self expanding proximal cage assembly and a distal filter, preferably a self-expanding cage assembly or other filter component. The various portions of those components are preferably radio-opaque. The proximal end of the proximal cage is typically is affixed to an actuator in such a way as to allow expansion of the cage after deployment. The proximal cage assembly may be used for collecting emboli or for displacing them to allow blood flow to resume, either with or without concurrent clot-dissolving drug treatment. The distal sector, whether a self-expanding cage or fan, is placed distally of the thrombus to collect portions of the thrombus which may loosen during the treatment or removal procedure.

    摘要： An embolism treatment device includes an elongated core wire having a coil tip coupled to the distal end of the core wire and a cage assembly substantially coaxial to the core wire, having a first deployment shape and a second expanded shape. The core wire is freely moveable axially through the cage assembly. The device additionally includes an inner coil surrounding the core wire within the cage assembly and an actuator element, having a first position and a second position, located proximally to the cage assembly, wherein when the actuator element is in the first position, the cage assembly is in the first deployment shape and when the actuator element is in the second position, the cage assembly is in the second expanded shape.
