A medical guidewire assembly comprises a guidewire (30) having a flexible tip (32). A medical device such as a collapsible filter (31) for use as an embolic protection device is mounted on the guidewire (30). The filter (31) is advanced through a body lumen with the guidewire tip (32) extending distally. At a first location the filter (31) is advanced relative to the tip (32) to a location which is distally advanced from the first location. Placement of the filter (31) in an optimal distal location is thereby achieved. |
