Patent Issued for Thrombectomy device system (USPTO 11583302).

The thrombectomy device of claim 13, wherein a number of the developing elements at the distal end of the thrombectomy stent is greater than or equal to 2, and the developing elements at the distal end of the thrombectomy stent are uniformly distributed at the distal end of the thrombectomy stent; a number of the developing elements at the proximal end of the thrombectomy stent is greater than or equal to 2, and the developing elements at the proximal end of the thrombectomy stent are uniformly distributed at the proximal end of the thrombectomy stent; and a number of the developing elements at the middle segment of the thrombectomy stent is greater than or equal to 2, and the developing elements at the middle segment of the thrombectomy stent are uniformly distributed at the middle segment of the thrombectomy stent. If the distal end and/or the proximal end of the thrombectomy stent is/are in a closed state, the outer diameter of the entire thrombectomy stent is reduced during thrombectomy, so that the thrombus is easy to be detached from the thrombectomy stent during thrombectomy due to the resistance of the vascular wall. The thrombectomy device of claim 11, wherein a number of the developing elements at the distal end of the thrombectomy stent is greater than or equal to 2, and the developing elements at the distal end of the thrombectomy stent are uniformly distributed at the distal end of the thrombectomy stent; and a number of the developing elements at the proximal end of the thrombectomy stent is greater than or equal to 2, and the developing elements at the proximal end of the thrombectomy stent are uniformly distributed at the proximal end of the thrombectomy stent.
