EMBOLIC PROTECTION DEVICES, SYSTEMS, AND METHODS

摘要

A catheter assembly includes a catheter body with a catheter-body lumen and an embolic protection device. The catheter body is sized for endoluminal advancement of a distal end portion of the catheter assembly from a puncture site at a human dorsalis pedis artery toward one or more larger arteries. The embolic protection device is configured with a collapsed state and a deployed state. The embolic protection device assumes the collapsed state while stowed in the catheter-body lumen at the distal end portion of the catheter assembly. The embolic protection device assumes the deployed state while outside the catheter-body lumen. The deployed state of the embolic protection device is configured with an opening away from the catheter body for capturing emboli dislodged from an arterial lesion while at a distal end of the arterial lesion.
