Title:
血栓摘出装置と血管から血栓を抽出する方法
Document Type and Number:
Japanese Patent JP7193625
Kind Code:
B2
Abstract:
A device and a thrombectomy apparatus for extraction of thrombus from a blood vessel are disclosed. The device comprises a segment changing its shape from a retracted position in a compressed state to an extended and expanded position. The segment is formed by a mesh of at least two sets of helicoidal filaments turning respectively in opposite directions and being intertwined. The mesh comprises two distinct tubular sections. The mesh of the first section has helicoidal filaments with a braiding angle providing radial forces higher than in the second section, thus the first section becomes appositioned against the inner wall of the blood vessel. The second section comprises two sub-sections. The first sub-section has a conical shape and comprises a braiding angle changing at its proximal and distal ends to provide radial strength to maintain the conical shape and to stop a proximal blood flow during the removal of the thrombus.
