摘要： The inventive stent delivery system includes a catheter having a retractable outer sheath near its distal end. A shape memory contraction member having a memorized contracted shape is connected to the retractable outer sheath. A heat generating device connected to the shape memory contraction member causes the shape memory contraction member to heat up to its transition temperature and assume its contracted position, retracting the retractable outer sheath. Another embodiment utilizes 2 springs, a “normal” spring and a shape memory alloy (SMA) spring, the two springs selected and designed so that the “normal” has an expansion force which is less than SMA spring when the SMA spring is austenitic, but greater than the SMA spring when the SMA spring is martensitic. Yet another embodiment utilizes a shape memory latch which in its martensitic state abuts a stop to prevent a spring from moving the sheath proximally, but in its austenitic state releases the stop, allowing the spring to retract the sheath to release the stent for deployment.

摘要： An improved expandable removal element for an atherectomy device wherein the expandable removal element is movable between an expanded position and a contracted position. In one embodiment of the present invention, a drive shaft is operatively connected to the distal end of the expandable removal element for rotating the removal element. A catheter surrounds a portion of the drive shaft. The catheter is shiftable with respect to the drive shaft for moving the material removal element between the expanded position and the contracted position. In another embodiment of the present invention, dual coaxial drive shafts are employed. The inner drive shaft and the outer drive are shiftable with respect to one another for moving the removal element between the expanded position and the contracted position. The present invention also describes several embodiments of a removal element for increasing the durability and effectiveness of the removal element. One embodiment of the removal element of the present invention comprised a plurality of braided wires having an abrasive disposed thereon. Another embodiment of a removal element is to provide a plurality of individual wires within each "braid" to increase the abrasive surface area of the removal element. In this " multi-ended" configuration, a plurality of wires are bundled together to form a single multi-ended strand. These single multi-ended strands are then braided together and an abrasive is disposed thereon to form the removal element. Finally, a number of novel methods for removing vascular occlusion material are provided.

摘要： Anchoring mechanisms for releasably securing an intravascular device along an elongated member such as a guidewire or catheter. The anchoring mechanism may include an object that can be actuated between an unlocked position and a locked position. In the unlocked position, the anchoring mechanism is slidably and rotationally disposed about the elongated member. In the locked position, the anchoring mechanism is releasably secured to the elongated member, preventing movement thereon. A placement mechanism such as a tubular member can be utilized to actuate the anchoring mechanism between the unlocked and locked positions.
