Embodiment Construction

[0059] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0060] "Distal" and "proximal" in the context of the present invention should be understood as viewed from the direction of the attending physician. The distal end is the side away from the attending physician, which relates to the components of the device of the invention advanced farther into the vascular system, while the proximal end means towards the attending physician, i.e. the proximally placed components of the device are introduced into the blood vessel without too far.

[0061] In the present invention, if the phrase "longitudinal direction" is used in ...

Abstract

The invention relates to a blood vessel thrombus-taking device with spine-shaped structures and a thrombus therapeutic instrument thereof. The blood vessel thrombus-taking device comprises a thrombus-taking instrument, a development ring located at the near-end of the thrombus-taking instrument and a development coil located at the far-end of the thrombus-taking instrument. The thrombus-taking instrument comprises a mesh tubular or cage-shaped structure composed of a plurality of mutually connected unit grids, and each unit grid is formed by embracement of mutually connected ribs. The ribs of the unit grids are provided with the spine-shaped structures respectively, and each spine-shaped structure extends into an outer cavity. The thrombus therapeutic instrument comprises the blood vessel thrombus-taking device with the spine-shaped structures, a protective sheath tube, a conveying wire, a micro catheter, a guide catheter and a rotary hemostasis valve. The micro catheter is pushed to the thrombus position in the guide catheter along the guide catheter, the protective sheath tube is communicated with the micro catheter through the rotary hemostasis valve, and the thrombus-taking instrument is placed in the protective sheath tube and pushed into the micro catheter through the conveying wire. The blood vessel thrombus-taking device is good in flexibility, and the thrombus-taking instrument can make the damage to the blood vessel wall smallest by bending a blood vessel or reaching a thin blood vessel at the far-end.

Description

technical field [0001] The present invention relates to a blood vessel thrombus retrieval device with a thorn-like structure and a thrombus treatment instrument thereof, in particular to a medical device for intervening in blood vessels, which is used to mechanically eliminate the thrombus when acute ischemic stroke occurs. It is a treatment method for the immediate restoration of blood flow for thrombus blocked in blood vessels, which is especially suitable for thrombus removal of intracranial blood vessels. Background technique [0002] Once ischemic stroke occurs, blood vessels must be recanalized within the shortest possible time (effective time window). At present, there are two main treatment methods for intracranial thrombosis: drug thrombolysis and mechanical thrombectomy. [0003] Drug thrombolysis is through intravenous injection of rt-PA (tissue plasminogen activator) or urokinase to dissolve thrombus, and can also be treated with intra-arterial exposure to throm...
