摘要： An assembly for breaking up vascular thrombus or other obstructive material including a motor housing having a motor, a motor shaft extending from the motor, a first housing positioned at a distal end of the motor shaft, a rotational thrombectomy wire and a second housing positioned at a proximal end of the wire. The first housing has a first magnet positioned therein and recessed from the distal edge of the first housing which has a first plurality of teeth. The second housing has a second magnet positioned therein and recessed from a proximal edge of the second housing which has a second plurality of teeth intermeshing with the first plurality of teeth when the wire is coupled to the motor shaft. The first and second plurality of teeth slip when a torque of the motor shaft exceeds a predetermined value.

摘要： A rotational thrombectomy wire for breaking up vascular thrombus or other obstructive material having a core having a proximal region and a distal region and being rotatable by a motor. The distal region has a smaller diameter than the proximal region. A cable is coupled to the distal region of the core and extends distally thereof. A torque tube is positioned over the cable and a coil is positioned over a distal portion of the cable. A distal portion of the cable has a non-linear configuration. A first covering material is positioned over the coil.

摘要： A distal protection device comprising a catheter having a first strut movable from a collapsed configuration to an expanded configuration having a first dimension and a second strut movable from a collapsed configuration to an expanded configuration having a second dimension larger than the first dimension. Movement of the first strut deploys filter material to a first position having a first deployed dimension and movement of the second strut to a first position deploys filter material to a second deployed dimension larger than the first expanded dimension.

摘要： A method and apparatus for caged stent delivery is provided herein. The device can be used to position and deliver any type of stent to a preselected treatment site within an intraluminal cavity. The device comprises a tubular portion, a plurality of arms attached to the distal end of the tubular portion, and a mechanism to open the arms. In operation, the caged device carries a stent in a constricted form to the treatment site for deployment. The arms of the cage are then opened, the stent released and deployed, and the device withdrawn. Several methods are provided to open the arms, including various pullwires, a piston, an electrolytic joint, and an activator. The arms may be constructed of a shape memory alloy and opened when shape memory behavior is effected. The device may be used with conventional catheters or used with a stent-loaded guidewire.
