A distal protection and delivery system is used to collect and remove embolic debris in the blood vessel. The system includes a guidewire, a filter assembly, and a distal introducer. The distal introducer can be positioned on a distal end of an introducer catheter or an angioplasty catheter or other interventional catheter. The guidewire has a small ferrule or locking mechanism fixed to it that does not affect the flexibility, torqueability, or trackability in comparison to standard guidewires. The introducer containing the filter assembly is advanced over the guidewire to a site distal to the lesion. Upon retraction of the guidewire proximally, the ferrule latches with an ejector latch of the filter assembly. Either advancement of the guidewire distally or retraction of the distal introducer proximally allows the filter assembly to be ejected from the distal introducer and into the blood vessel.
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 delivery system for deploying and retrieving a distal protection filter assembly out of and back into an introducer from an initial smaller undeployed state to a larger deployed state and then to a smaller removable state into and out of the vasculature for filtering embolic debris out of blood that is flowing through the vasculature and removing the embolic debris captured by the distal protection filter assembly along with the distal protection filter assembly, said delivery system comprising;
A method of use for a delivery system for introduction of a distal protection filter assembly into the vasculature for filtering embolic debris in flowing blood, the distal protection filter assembly expanding from a smaller nondeployed state to a larger deployed state, the method comprising;
A method of use for a delivery system for removal of a distal protection filter assembly from the vasculature for removing embolic debris captured from flowing blood, the distal protection filter assembly contracting from a larger deployed state to a smaller nondeployed state, the method comprising;
A method of use for a delivery system for introduction of a distal protection filter assembly into the vasculature for filtering embolic debris in flowing blood, and performing an interventional procedure, the method comprising;
