    摘要： Anchoring mechanisms for limiting travel of an intravascular device along an elongated member such as a guidewire or guide catheter are disclosed. The anchoring mechanism may include a leaf spring that can be actuated between an unlocked position and a locked position. In the unlocked position, the leaf spring is slidably and rotationally disposed along the elongated member. In the locked position, the leaf spring is releasably secured to the elongated member, preventing movement thereon. The leaf spring can be attached directly to the intravascular device, or can be formed as a separate member and used as a stopper mechanism to limit travel of the intravascular device along the elongated member.

    摘要： Devices and methods for centering an intravascular filter within a blood vessel are disclosed. A filter system in accordance with an exemplary embodiment of the present invention may include an intravascular filter, a filter sheath adapted to contain the intravascular filter, and a centering member adapted to assume a preset shape when deployed within a blood vessel. The centering member may comprise an elongated wire having a hoop section adapted to radially expand against the inner wall of the blood vessel when deployed. In some embodiments, multiple centering members can be employed to facilitate centering of both the intravascular filter and the filter sheath within the blood vessel, if desired.
