Sheathless embolic protection system
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 at a site of a stenosis, 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; 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 a compressing element, for compressing the filter device so as to enable the filter device to be inserted over the guide wire, to the position distal to the interventional procedure site, in a low profile for crossing the stenosis, and without a sheath extending about the filter device, adapted to enable release thereof so as to enable expansion of the filter device for deployment thereof.

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 compressed for insertion thereof through a patient'"'"'s vasculature so as to cross the stenosis in a low profile, and to enable release of compression thereof for expansion and deployment of the device at a location distal to the interventional procedure site.

21. A method of enabling the capture of embolic material which may be released into a blood vessel during a therapeutic interventional procedure at a site of a stenosis, in a system which comprises 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, 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 a compressing element, for compressing the filter device so as to enable the filter device to be inserted over the guide wire, to the position distal to the interventional procedure site, in a low profile for crossing the stenosis, and without a sheath extending about the filter device, adapted to enable release thereof so as to enable expansion of the filter device for deployment thereof, wherein the method comprises:
-
compressing the filter device, comprising engaging the compressing element with the filter device;
engaging the compressed filter device with the distal end of the guide wire;
delivering the compressed filter device engaged with the guide wire in a low profile for crossing the stenosis and without a sheath extending thereabout, to the location in the patient'"'"'s vasculature distal to the interventional procedure site; and
releasing the compressing element so as to release the filter device from compression thereof, for expansion and deployment of the filter device. - View Dependent Claims (22, 23, 24, 25, 26, 27)
