Claim 0:
1. A thrombus removal device, wherein the thrombus removal device comprises an elongated delivery member and a plurality of thrombus removal members disposed on the elongated delivery member, each thrombus removal member among the plurality of thrombus removal members having a compressed configuration and an expanded configuration formed from the compressed configuration by means of self-expansion; and at least one thrombus removal member among the plurality of thrombus removal members is rotatably connected to the elongated delivery member, wherein the plurality of thrombus removal members comprise at least a first thrombus removal member and the second thrombus removal member, wherein the first thrombus removal member and the second thrombus removal member are rotatably coupled to the elongate delivery member, and a thrombus can be clamped between the first thrombus removal member and the second thrombus removal member;
wherein the first thrombus removal member and the second thrombus removal member each comprises:
a connecting member located at a proximal end of the thrombus removal member; and
a grid frame extending towards a distal direction from the connecting member; the grid frame of the thrombus removal member comprises a plurality of first stent bars connected to the connecting member; the plurality of first stent bars extend towards a distal direction in a spirally mutually-separated manner from a starting part which is the connection part between each of the first stent bars and the connecting member; and
wherein each of the plurality of first stent bars comprises an end of the first stent bar that is split into two second stent bars extending in the distal direction in a mutually separated manner, and
among a plurality of second stent bars separated by two adjacent first stent bars, two adjacent second stent bar ends separated by different first stent bars meet at a point forming a V-shaped structure; and
an included angle formed by the inner tangents on both curved sides of the “V”-shaped structure increases first and then decreases from a proximal direction to the distal direction of the thrombus removal member.
