摘要：
Embolic protection filtering devices and methods for making and using the same. An example embolic protection filter device may include an elongate shaft. A filter may be coupled to the shaft. The filter may include a filter frame and a filter membrane having a plurality of apertures formed therein attached to the filter frame. The filter may be configured to shift between a first collapsed configuration and a second expanded configuration. The apertures may have a first shape when the filter is in the first configuration and a second shape when the filter is in the second configuration.
