EMBOLIC PROTECTION DEVICE WITH LOCKING DEVICE
First Claim
1. A device for locking onto a guidewire, comprising:
- an element transversely movable along the guidewire, the element comprising a plurality of portions; and
a biasing member connecting a first portion and a second portion of the transversely moveable element;
the first portion and another portion of the transversely moveable guide member being movable from a first position, where the first portion and the other portion are aligned with respect to one another, to a second position, where the first portion is not aligned with respect to the other portion, the device being locked to the guidewire in the second position.

Abstract
A device and method for locking onto a guidewire. The device includes an element transversely movable along the guidewire. The element may have a plurality of portions and a biasing member connecting first and second portions of the transversely moveable element such that the first portion and another of the portions are movable from a first position, where the first portion and the other portion are aligned with respect to one another, to a second position, where the first portion is no longer aligned with respect to the other portion, the device being locked to the guidewire in the second position. The device can be used for locking an embolic protection device including a filter to a guidewire that is adapted to be introduced into a vascular system of a patient.

27. A method for locking a device onto a guidewire, the guidewire including a stiff portion with a first stiffness and a floppy portion with a second, lesser stiffness, and the method comprising:
-
advancing the device along the stiff portion of the guidewire, the device comprising a plurality of portions aligned with respect to one another at a first position, wherein a first and a second portions of the device are connected by a biasing member; providing the device at the floppy portion of the guidewire; and biasing the first portion so that the first portion is not aligned with respect to another portion of the device at a second position, whereby the device is locked to the guidewire. - View Dependent Claims (28, 29, 30)

33. A method for locking a device onto a guidewire, the guidewire including a stiff portion with a first stiffness and a floppy portion with a second, lesser stiffness, and the method comprising:
-
advancing the device along the stiff portion of the guidewire, the device comprising an element transversely movable along the guidewire, the element comprising a collet portion, the collet portion having at least one deflectable tooth feature, wherein the tooth feature can be deflected from a first position to a second position, the device being locked to the guidewire in the second position; providing the device at the floppy portion of the guidewire; and biasing the tooth element so that the guidewire becomes pinched between the tooth element and an opposing surface of the collet, whereby the device is locked to the guidewire.

36. A method for locking a device onto a guidewire, the guidewire including a stiff portion with a first stiffness and a floppy portion with a second, lesser stiffness, and the method comprising:
-
advancing the device along the stiff portion of the guidewire, the device comprising an element transversely movable along the guidewire, the element comprising a tubular portion, wherein the tubular portion can be deformed from a first position to a second position, the device being locked to the guidewire in the second position; providing the device at the floppy portion of the guidewire; and deforming the tubular portion to the second position, so that a lumen of the tubular portion reduces in profile, thereby pinching the guidewire and locking the device to the guidewire.
