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.
