Claims25
A method for capturing emboli from blood flowing through a body vessel during therapeutic treatment at a treatment site in the vessel comprising:
- introducing a guidewire into the vessel;
- advancing the guidewire distally through the vessel;
- positioning a distal end of the guidewire at a location distal to the treatment site;
- introducing an elongate introduction member into the vessel;
- advancing the elongate introduction member distally through the vessel;
- positioning a distal end of the elongate introduction member at a location distal to the treatment site;
- removing the elongate introduction member from the vessel;
- after the elongate introduction member has been removed introducing a treatment catheter into the vessel;
- advancing the treatment catheter distally over the guidewire;
- positioning the treatment catheter at the treatment site;
- performing a therapeutic treatment at the treatment site with the treatment catheter;
- capturing emboli released into the blood during the therapeutic treatment at a location between the treatment site and the distal end of the guidewire;
- removing the treatment catheter from the vessel;
- after the treatment catheter has been removed introducing a retrieval member into the vessel;
- advancing the retrieval member distally over the guidewire;
- and
- retrieving the captured emboli from the vessel with the retrieval member.
