Abstract: A retrieval catheter for retrieving a medical device deployed in a vasculature. The catheter comprises an outer catheter body and an inner coupling member having means for coupling to a medical device deployed in a vasculature. The catheter body is movable distally relative to the coupling member to retrieve a coupled medical device into the catheter body.

Abstract: An embolic protection filter system comprises a collapsible embolic protection filter 62 having a collapsed configuration for delivery of the filter, and a deployed configuration and a temporary lumen defining member 60. The lumen defining member 60 is used for loading a filter-containing delivery catheter 63 onto a guidewire 65. After loading, the member 60 can be removed by pulling on a tab 61.

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.
