Embolic protection filtering guidewire

An embolic protection filtering guidewire is a steerable catheter-like wire with a deployable filter at its tip, designed to protect blood vessels during procedures like angioplasty or stent placement. When inserted past a blockage (such as plaque), the filter expands to trap debris (emboli) that could otherwise travel and cause blockages elsewhere in the circulatory system.

These devices are typically single-use and regulated as medical devices, with classification and supply rules varying by jurisdiction. They are often used in coronary, carotid, or peripheral arteries and may include accessories like deployment sheaths for safe removal after use.
