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; 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.

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 be pre-formed for expansion thereof so as to seal off the inner surface of a blood vessel, to inhibit the forming of a gap therein, for inhibiting embolic material from passing therethrough, and to be foreshortened to enable insertion thereof through confined spaces. The system, in another embodiment thereof, enables expandable material to be formed into an expandable configuration of an embolic protection device for capturing embolic material, which is capable of sealing off the inner surface of the blood vessel.

27. 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; 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 pre-formed expandable shape thereof, which includes a pre-formed expandable maximum outer diameter portion, adapted to expand against the inner surface of the wall of the blood vessel, and to extend along and seal off the inner surface of the blood vessel wall, upon expansion of the filter device for deployment thereof, so as to inhibit the formation of a gap between the filter device and the blood vessel wall through which embolic material may otherwise flow. - View Dependent Claims (28, 29)

30. 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; 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, wherein the length of the filter device is foreshortened, such that the length thereof is shortened for insertion thereof through the patient'"'"'s vasculature. - View Dependent Claims (31, 32)

33. A system for enabling expandable material to be pre-formed into an expandable configuration of a cage for a filter device, for preforming the cage, for enabling the filter device to capture embolic material which may be released into a blood vessel during a therapeutic interventional procedure, wherein the expandable configuration of the cage to be pre-formed by the system provides a substantially uniform pre-formed expandable maximum outer diameter portion thereof, for maintaining vessel wall opposition in a patient'"'"'s vasculature upon deployment of the cage at a location distal to an interventional procedure site, comprising:
-
a male mandrel element, adapted to enable the expandable material to be extended thereover, including a maximum outer diameter portion extending along the length thereof which is substantially uniform and is substantially equal to the maximum inner diameter portion of the expandable configuration of the cage to be formed thereby; and
a female die element, adapted to enable the expandable material to be formed therein, adapted to extend over the male mandrel member and the expandable material, having a cavity therein, the length of which extends for at least a portion of the length of the male mandrel member, the maximum diameter of which is substantially uniform and is substantially equal to the maximum outer diameter portion of the expandable configuration of the cage to be formed thereby. - View Dependent Claims (34, 35, 36, 37, 38)

39. A method of enabling the capture of embolic material which may be released into a blood vessel during a therapeutic interventional procedure, 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 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 method comprises:
-
snap-fitting the filter device so as to engage the distal end of the guide wire;
