  • Publication number: 20030212429
    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.

  • Publication number: 20030187474
    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.

  • Publication number: 20030109886
    Abstract: A delivery catheter 1 for rapid exchange delivery of a stent 7 through a vasculature over a guidewire 10, and for rapid exchange deployment of the stent 7 at a desired site in the vasculature. The catheter 1 comprises a hypotube 2, a distal sheath 4 which defines an internal reception space for the stent 7, and a push wire 3. The catheter body 2 is fixedly attached to the sheath 4 by means of a junction piece 9. At the distal end of the wire 3, the catheter 1 comprises a tubular inner core 5 and a coiled spring 6 which acts as an abutment means for engagement with the stent 7 in the reception space upon retraction of the sheath 4 to facilitate deployment of the stent 7. The guidewire 10 passes proximally from the inner core 5, through the junction piece 9, and out of the junction piece 9 through a proximal guidewire opening 11.
