Abstract:
A delivery system for delivering a distal protection filter assembly into the vasculature by an introducer for filtering embolic debris in flowing blood, the distal protection filter assembly being capable of extending from a smaller nondeployed state to a larger deployed state, said delivery system comprising;A. a guidewire having a locking means, B. an introducer that holds the distal protection filter assembly in the smaller nondeployed state, C. a stop means having the distal protection assembly attached thereto and preventing the passage of said locking means therethrough, D. an ejector means interacting with the distal protection filter assembly and providing for relative movement between the distal protection filter assembly and said introducer to eject the distal protection filter assembly from said introducer and into the vasculature allowing expansion of the distal protection filter to a larger deployed state.
