Filter device for embolic protection systems
First Claim
1. A system for enabling the capture of embolic material which may be released into a blood vessel during a therapeutic interventional procedure, comprising:
- a guide wire, including a distal end, adapted to be positioned within the blood vessel and to extend to a position distal to an interventional procedure site, the guide wire including a proximal stop and a distal stop, adapted to be secured to the distal end of the guide wire, and having a space between the proximal stop and the distal stop; and
a filter device, adapted to be positioned and deployed at a location in the patient'"'"'s vasculature distal to the interventional procedure site, and to capture embolic material which may be released into the blood in the blood vessel during the interventional procedure, including an engaging element, for enabling the filter device to be snap-fitted so as to engage the distal end of the guide wire;
wherein the engaging element of the filter device includes a snap-fitting component and is adapted to enable snap-fitting engagement within the space formed between the proximal stop and distal stop.

Abstract
A system for enabling the insertion and removal of an embolic protection device, for capturing and retaining embolic debris which may be created during the performance of a therapeutic interventional procedure in a stenosed or occluded region of a blood vessel. The system, in an embodiment thereof, enables the device to be snap-fitted so as to engage the distal end of a guide wire, to provide a reference for positioning the device at a location distal to the interventional procedure site, and to enable an end of the device to be in tension, enabling a portion of the device to be in tension and another portion to be in compression, so as to assist in bending thereof in tortuous vasculature.

16. A method of enabling the capture of embolic material which may be released into a blood vessel during a therapeutic interventional procedure using a system which includes a guide wire having a distal end and a proximal stop, a distal stop and a space formed between therebetween, adapted to be positioned within the blood vessel, and a filter device adapted to be positioned and deployed at a location in the patient'"'"'s vasculature distal to the interventional procedure site to capture embolic material, including an engaging element including a snap-fitting component, for enabling the filter device to be snap-fitted so as to engage the distal end of the guide wire, wherein the method comprises:
-
snap-fitting the filter device so as to engage the space created between the proximal stop and the distal stop of the guide wire; inserting the filter device and the guide wire to the location in the patient'"'"'s vasculature distal to the interventional procedure site; and expanding the filter device for deployment thereof. - View Dependent Claims (17, 18)
