Problems solved by technology

[0006] A drawback of thrombolytic therapies is that they are rarely successful once the available time period has elapsed
Tethering to the guidewire via a tapered structure (teardrop structure) in particular leads to a streamlined shape of the proximal region of the structure under tension, which hampers the efficiency of this structure

Embodiment Construction

[0039] figure 1 and 3 Two variants of the cylindrical stent structure 1 of the invention are shown with separate meshes 3 and 4 and connectors 5 and 5'. Mesh 3 and 4 are of different types, one type (3) has a wavy shape and the other type (4) has a spherical shape with two points. When acting together, these two shapes provide an overall structure that is both stable and flexible.

[0040] exist figure 1 and 3 In the planar, two-dimensional representation of , a slit or channel 7 extends through the stent structure, said slit or channel being bridged by a tension clip 9 at the proximal end of the structure. The slit 7 is delimited by the transverse faces 10 and 10' of the mesh structure. The slots 7 run not parallel to but obliquely to the longitudinal axis of the structure, represented in three-dimensional view as a helical course along the shell surface (cf. figure 2 / 4).

Abstract

The invention relates to a thrombectomy device having a substantially cylindrical stent structure (1) comprised of a plurality of meshes (3, 4) and also two connectors (5, 5′) that are disposed at different meshes (3) at the proximal end of the stent structure (1). The device also has a guide wire (12), which comprises a coupling element (11) to which the connectors (5, 5′) are coupled, and a slit (7), which extends helically over the shell face (8) of the stent structure (1), and a tensioning clip (9) that spans the slit (7) at the proximal end.

Description

technical field [0001] The present invention relates to a thrombectomy device having a substantially cylindrical stent structure, comprising a plurality of meshes and two connectors arranged at the proximal end of the stent structure on different meshes, and comprising a guide wire with a coupling element, the connector Join to a join component. The thrombus removal device is especially designed for removing thrombi in areas of the brain where stroke attacks are frequently encountered, for example, in a manner that is gentle and reliable to the patient. Background technique [0002] Thromboembolic diseases such as myocardial infarction, pulmonary embolism, peripheral thrombosis, organ embolism, etc. are typically caused by a thrombus (hereinafter simply referred to as a thrombus) trapped in a blood vessel and blocking it completely or partially, i.e. by platelets, fibrinogen , coagulation factors and other components of viscoelastic blood clot trigger. Blockage of an organ...
