Abstract
The present disclosure provides an embolic protection device comprising a metal wire or metal ribbon with an elliptical or flat cross-section, pre-formed into a spiral structure wound around its short axis. The formed embolic protection device can be deployed within a tubular object and introduced into the target blood vessel through the tube. The elasticity of the material enables it to revert to a predetermined shape, thereby effectively intercepting emboli. The device is characterized by a smaller curvature, enhanced recovery to the preset shape, and reduced interference with blood flow.
