Abstract

A mechanical thrombectomy device, and methods of manufacturing and using the mechanical thrombectomy device, are described. The mechanical thrombectomy device includes several clot arrestors independently mounted on a support wire. The clot arrestors have expandable frames that are eccentrically supported on the support wire. The independently and eccentrically mounted clot arrestors are arranged to allow a clot to pass into, and be captured by, one of the expandable frames. Furthermore, the independently and eccentrically mounted clot arrestors deform independently of one another such that retraction of the mechanical thrombectomy device through tortuous vasculature can stretch one clot arrestor without stretching another one of the clot arrestors to allow the clot to be retained by the unstretched clot arrestors. Other embodiments are also described and claimed.
