摘要:
An embolic protection device includes a shaft, a first magnet fixedly coupled to a distal portion of the shaft, a second magnet slidingly coupled to the shaft proximal to the first magnet, and a filter including a distal portion coupled to the first magnet and a proximal portion coupled to the second magnet. The first and second magnets are magnetically attracted to each other such that in a radially compressed configuration of the filter, the second magnet is spaced from the first magnet a first distance, and in a radially expanded configuration of the filter, the second magnet slides towards the first magnet such that the second magnet is spaced a second distance from the first magnet, wherein the second distance is smaller than the first distance.
