Embolic protection system
First Claim
1. An embolic protection filter for deployment in a vasculature, the filter having an inlet end and an outlet end, the inlet end having one or more inlet openings sized to allow blood and embolic material enter the filter, and the outlet end of the filter having a plurality of outlet openings sized to allow through passage of blood but to retain undesired embolic material within the filter;
- the filter being movable between a collapsed configuration for movement through a vasculature, and an outwardly extended configuration for deployment in a vasculature;
the filter at least in the collapsed configuration having a guidewire lumen defined at least partially therethrough for passing the filter over a guidewire;
wherein the guidewire lumen is defined by a lumen-defining member which is spaced proximally of the distal end of the filter.

Abstract
An embolic protection filter for deployment in a vasculature, the filter having an inlet end and an outlet end, the inlet end having one or more inlet openings sized to allow blood and embolic material enter the filter, and the outlet end of the filter having a plurality of outlet openings sized to allow through passage of blood but to retain undesired embolic material within the filter. The filter is movable between a collapsed configuration for movement through a vasculature, and an outwardly extended configuration for deployment in a vasculature. The filter at least in the collapsed configuration was a guidewire lumen defined at least partially therethrough for passing the filter over a guidewire. The guidewire lumen is defined by a lumen-defining member which is spaced proximally of the distal end of the filter.

11. An embolic protection filter for deployment in a vasculature, the filter having an inlet end and an outlet end having one or more inlet openings sized to allow blood and embolic material enter the filter, and the outlet end of the filter having a plurality of outlet openings sized to allow through passage of blood but to retain undesired embolic material within the filter;
-
the filter being movable between a collapsed configuration for movement through a vasculature, and an outwardly extended configuration for deployment in a vasculature in apposition with a vasculature wall;
in the outwardly extended configuration of the filter exerting an outward radial force on a vasculature wall sufficient to retain the filter in position against substantial longitudinal movement. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
