Title:
VASCULAR RECANALIZATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/027190
Kind Code:
A1
Abstract:
Some embodiments of the present application provide a vascular recanalization apparatus. The vascular recanalization apparatus comprises: a guide wire (1), a sleeve (2), and a control assembly (3). The guide wire (1) comprises a spiral torsion section and a supporting section which are sequentially connected from the distal end to the proximal end, wherein the spiral torsion section can expand and contract radially. The guide wire (1) penetrates through the sleeve (2) and can move axially and rotate circumferentially relative to the sleeve (2). The proximal end of the sleeve (2) is connected to the distal end of the control assembly (3); the proximal end of the supporting section is connected to the control assembly (3); the control assembly (3) can drive the guide wire (1) to move axially relative to the sleeve (2) so as to make the spiral torsion section extend out of or be accommodated in the sleeve (2); and the control assembly (3) can drive the spiral torsion section extending out of the distal end of the sleeve (2) to move axially.
