AI Technical Summary
Existing clot retrieval devices struggle to effectively remove occlusive clots from blood vessels, particularly those with high fibrin content, often requiring multiple passes and causing difficulty in dislodgement and retrieval.
A clot retrieval device designed with a self-expanding structure made from superelastic materials like Nitinol, featuring alternating high and low radial force segments to minimize clot compression, facilitate pinching, and incorporate a distal fragment capture portion, allowing for enhanced grip and control during retraction.
The device improves clot retrieval efficiency by minimizing compression, increasing grip on the clot, and reducing the force required for dislodgement, especially for fibrin-rich clots, while providing protection against distal migration of fragments.
