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.

92. A method for the capture and removal of embolic material from a vasculature during an interventional procedure comprising the steps of:
-
providing a collapsible embolic protection filter having a collapsed configuration for delivery of the filter, and a deployed configuration; advancing a guidewire through a vasculature; crossing a desired treatment location with the guidewire; deploying the filter distal to the treatment location; carrying out an interventional procedure at the treatment location, embolic material generated during the treatment procedure being captured by the deployed filter; advancing a retrieval device; engaging the filter with the retrieval device independent of the guidewire; and withdrawing the retrieval device and the filter from the vasculature, wherein the deployed filter is retained independent of the guidewire against substantial longitudinal movement. - View Dependent Claims (93, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106)

121. A method for the capture and removal of embolic material from a vasculature during an interventional procedure comprising the steps of:
-
providing a collapsible embolic protection filter having a collapsed configuration for delivery of the filter, and a deployed configuration; advancing a guidewire through a vasculature; crossing a desired treatment location with the guidewire; deploying the filter distal to the treatment location; withdrawing the guidewire from the filter and/or the desired treatment location; and subsequently placing a guidewire in the filter; carrying out an interventional procedure at the treatment location, embolic material generated during the treatment procedure being captured by the deployed filter; advancing a retrieval device; engaging the filter with the retrieval device; and withdrawing the retrieval device and the filter from the vasculature. - View Dependent Claims (122, 123, 124, 125, 126, 127, 132, 133, 134, 135)
