Abstract: 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.

Abstract: An embolic protection filter having an improved filter frame and method of making the same. In at least some embodiments, the present invention includes an embolic protection filter coupled to an elongate shaft. The filter may include a filter frame assembly having one or more frame members. The frame members may include a filter mouth defining portion.

Abstract: A temporary stent for supporting a region of a vessel in a body comprising a composite stent portion and an actuator portion and methods for the use and manufacture thereof. The composite stent portion is comprised of an elongate perfusable vessel supporting portion adapted to be configurable between a reduced size for placement in the vessel and removal therefrom and an expanded size for structurally supporting the vessel and perfusable end portions connected to and forming ends of the vessel supporting portion and adapted to allow fluid flow therethrough. The composite stent portion is comprised of a plurality of resilient metallic wires coated with a polymeric material to provide stability for both lifting and maintaining a vessel. A method is disclosed for deployment of the composite stent to maintain vessel patency during occurrence of an intimal flap, vasoconstriction or vasospasm.
