Abstract
The invention relates to a thrombectomy device with a substantially cylindrical stent structure (1), which has a multiplicity of meshes (3, 4) and two connectors (5, 5′) that are arranged on different meshes (3) at the proximal end of the stent structure (1), and with a guide wire (12), which has a coupling element (11) to which the connectors (5, 5′) are coupled, with a slit (7), which extends in a helical formation across the jacket surface (8) of the stent structure (1), and with a tensioning bow (9), which spans the slit (7) at the proximal end.

Thrombectomy device with
- an essentially cylindrical stent structure (1) having a plurality of meshes (3, 4) generating a surface (8) as well as two connectors (5, 5′) arranged at different meshes (3, 3′) of the plurality of meshes (3,4) at the proximal end of the stent structure (1), and
- a guidewire (12) provided with a coupling element (11) arranged proximally to which the connectors (5, 5′) are attached,
- wherein the stent structure is characterized by a continuous slot (7) open at a distal end thereof and extending in a helical or coiled fashion over and throughout the length of the generated surface (8) of the stent structure (1), and a retaining clip (9) spanning the slot (7) in a wave-like manner at the proximal end of the stent structure (1),
- the retaining clip (9) being attached to rims (10, 10′) of the stent structure (1),
- wherein the retaining clip (9) forms an arch that points to the distal end of the stent structure (9), and
- wherein the retaining clip (9) and the connectors (5, 5′) form a loop that terminates in the coupling element (11).
