Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with accompanying drawing and specific embodiment: As shown in Figure 1, the bioceramic thrombus filter of controllable release in the embodiment of the present invention is to adopt the NiTi alloy tube with shape memory function to pass through the laser Engraving, and then coating the metal surface with a bioceramic film or pre-plating a bioceramic film on the metal surface. It is in the form of tight tube bundles in the compressed state and conical network in the released state. The thrombus filter in the present invention includes a front end 6 , a rear end 1 , a front section 4 , a middle section 3 , a rear section 2 and an elastic wire 10 . Among them, the middle section 3 is composed of straight rods, which are equally divided and rotated in the circumferential direction to form concentric cylindrical beams. The front section 4 and the rear section 2 are filter screens, and the shape ...

Abstract

The present invention relates to a controllably-released bioceramic thrombus filter and its preparation method. Said thrombus filter is made up by using laser engraved metal tube, its end portion is equipped with a combination portion matched with a conveying portion, its centre is equipped with an elastic wire and its surface is convered with a layer of bioceramic membrance. It can be temporarily placed into blood vessel of human body, also can be permanently placed in the blood vessel of human body. Said invention also provides the concrete working principle of said thrombus filter.

Description

technical field [0001] The invention relates to a medical device, in particular to a controllable-release bioceramic thrombus filter for treating pulmonary embolism (PE) and a manufacturing method thereof. Background technique [0002] Pulmonary thromboembolism, or pulmonary embolism (PE) for short, is a cardiovascular disease that seriously endangers people's health. The current treatment methods are mainly thrombolytic therapy, anticoagulant therapy and surgical treatment, but for those patients who have contraindications to anticoagulant therapy, have bleeding complications, and are not suitable for surgical treatment, interventional therapy can be used, that is, A mechanical device is placed in the vena cava to prevent the thrombus from ascending and prevent or reduce pulmonary thromboembolism. This method has the advantages of small trauma, safety, good curative effect, simple operation, short hospital stay, and quick recovery of the patient. [0003] There are many t...
