Embodiment Construction

[0080] A type of intracavity implant structure in the prior art includes a central part with a central axis and a functional part with a periphery composed of several bars extending outward from the central part. The periphery of the functional part surrounds the central axis and can be surrounded by the inner wall Compression towards the central axis maintains the implant in position within the lumen into which it is implanted. A typical implant structure of this type can be found in the filter structure disclosed in WO2017186025A1 of the inventor of the present application, which is incorporated into this patent in its entirety. The above-mentioned implant in a relatively strong compressed state has a small shape and volume, so it can be placed in the sheath, and transported in the human cavity through the sheath, and operated by the operator at the desired position, so that the implant The body is released from the sheath, and the above-mentioned implant in a relatively str...

Abstract

The invention relates to the technical field of implanted medical instruments, in particular to an intracavitary implant structure, particularly relates to a vena cava filter, and concretely disclosesan intracavitary implant structure and a vena cava filter with the intracavitary implant structure. The vena cava filter comprises a center part and a function part, wherein the center part is provided with a center axial line; and the function part outwards extends from the center part, is formed by a plurality of rods and is provided with a periphery. Through the improvement on the arrangement,the structure and the shape of the rods for forming the function part, an implant achieves the effects of better centrality and the like.

Description

technical field [0001] The invention relates to the technical field of implanted medical devices, in particular to an implant structure in a cavity, in particular to a vena cava filter. Background technique [0002] Implantable medical devices refer to medical devices that can stay in the body for a short or long term, are used to support and sustain life, are potentially dangerous to the human body, and must be strictly controlled for their safety and effectiveness. Expandable implantable medical devices such as vascular stents, vena cava filters, occluders, and ventricular volume reduction devices can be compressed to a very small volume and implanted into the human cavity through interventional procedures. The compressed devices are released and expanded at the desired position in the body Finally, therapeutic effects are achieved, such as expansion, support, blockage, volume reduction of blood vessels or body cavities, or prevention of thrombus circulation in the blood. ...
