distal protection device
Embolic protection system used during endovascular procedures to capture debris and prevent downstream embolization.
Full Definition
A distal protection device is a specialized catheter-based system designed to prevent embolization of atherosclerotic debris during endovascular interventions, particularly carotid artery stenting. These devices typically function as either filters or occlusion balloons positioned distal to the treatment site to capture or prevent the passage of dislodged plaque material. The use of distal protection devices is considered standard of care in carotid interventions due to the risk of stroke from cerebral embolization. Editors should distinguish between different types (filter-type vs. balloon occlusion) and ensure accurate terminology in procedural documentation.
Usage
Usage note: Distinguish between filter-type and balloon occlusion variants in documentation.
