distal protection device
Interventional tool designed to capture embolic debris during vascular procedures to prevent downstream organ damage.
Full Definition
Distal protection devices are specialized catheters or filters deployed beyond the target lesion during interventional procedures to capture embolic material released during treatment. These devices are particularly important in carotid artery stenting and saphenous vein graft interventions where embolization could cause stroke or myocardial infarction. Types include filter baskets, occlusion balloons, and aspiration systems, each with specific advantages and limitations based on vessel anatomy and lesion characteristics.
Usage
Usage note: Specify type (filter, balloon occlusion, or aspiration) when documenting use.
