Beschreibung
Zusammenfassung:	A system for recovering an embolic protection device having an expandable filter disposed on a guide wire includes an inner catheter loaded inside a recovery sheath. The inner catheter has a distal portion which extends beyond the distal end of the recovery sheath when the recovery system is being advanced over the guide wire of the embolic protection device. The inner catheter has more flexibility than the recovery sheath, and enhances delivery through tortuous anatomy to the location of the deployed filter. Once the recovery system is advanced in close proximity to the expandable filter of the embolic protection device, the recovery sheath is advanced over distal portion of the inner catheter and over the expandable filter to collapse the filter for removal from the body vessel. The recovery sheath has sufficient column strength to collapse the expanded filter for removal from the body vessel.
