摘要:
A device for extraction of thrombus from a blood vessel and a thrombectomy apparatus. The device comprises a segment (10) configured to change its shape from a retracted position in a compressed state to an extended and expanded position, to be appositioned against the inner wall of a blood vessel to receive and retain a thrombus. The segment (10) is formed by a mesh (13) of at least two sets of helicoidal filaments turning respectively in opposite directions and being intertwined. The mesh (13) comprises two distinct tubular sections, wherein a second section (30), adjacent to a first section (20), provides a reduction of diameter and wherein the mesh (13) of the first section (20) has a variable density of the helicoidal filaments to provide radial forces higher than in the second section (30), such that the first section (20) becomes appositioned against the inner wall of the blood vessel.
