The embolic protection filter body has a guidewire path for slidably receiving the guidewire to permit movement of the filter relative to the guidewire when the filter 1 is in the collapsed configuration and the expanded deployed configuration. A delivery catheter is advanceable over the guidewire for delivery of the embolic protection filter. A retrieval catheter is also advanceable over the guidewire for retrieval of the filter , and engagement elements are used for engaging the embolic protection filter with the guidewire for retrieval of the filter into the retrieval catheter in the collapsed configuration.

DETAILED DESCRIPTION Referring to the drawings there is illustrated a transvascular embolic protection system according to the invention for safely capturing and retaining embolic material released during an interventional procedure while maintaining blood flow.
The flushed filter element 40 is now ready for loading into the pod 13 of the delivery catheter 2. The pushing device 8 is rotated through 90� in a �bolt-action� to release the handle 70 from the snap-fit retaining projections 9 in the tray 5, as illustrated in FIGS. 28 and 29. In this configuration the pushing device is still retained to the tray (FIG. 29A).The pushing device 8 is now free to slide proximally in the channel 6 (FIG. 30), until the distal stop 72 engages with the distal end 49 of the sleeve 43 of the filter element 40 (FIGS. 31( a) and 31(b)). Continued pushing of the pushing device 8 will push the filter element 40 proximally towards the loading device 7 (FIG. 31( a)), through the loading device 7, thereby collapsing the filter element 40 from the extended outwardly projecting position of FIG. 31( a) to the collapsed position of FIG. 32( a), and into the pod 13 of the delivery catheter 2 (FIG. 32( a)) until the filter element 40 abuts the distal end 27 of the inner stem 28 of the inner catheter 25. Further pushing of the pushing device 8 moves the collapsed filter element 40 and the inner catheter 25 proximally until the O-ring shoulder 30 of the inner catheter 25 abuts the annular collar 31 fixed in the proximal opening 17 of the handle 14, as illustrated in FIGS. 14 and 15. An O-ring 39 is also provided between the shoulder 30 and the collar 31.
