Problems solved by technology

Permanent filters are widely used. After being implanted into the vena cava, they are fixed on the vessel wall and accompany the patient for life. However, this filter remains in the body for a long time as a foreign body, which may cause displacement, vena cava perforation, local thrombosis, and inferior vena cava obstruction. Serious complications; long-term or even life-long anticoagulation due to use of permanent filters is inconvenient for many patients, especially young patients
Temporary filters can be removed from the body within a certain period of time, thereby avoiding the problems caused by implanting permanent filters, but in practical applications, due to tissue adhesion, wrapping, etc., temporary filters may not be recovered smoothly

Embodiment Construction

[0028] Below in conjunction with accompanying drawing and specific embodiment the present invention will be further described:

[0029] see Figure 1 to Figure 9 , this embodiment provides a retrievable vascular filter assembly, including an introduction system and a recovery system, the introduction system includes a filter body 1 and an indwelling guide wire 2, the recovery system includes an extension guide wire 3 and a recovery sheath 4, the filter body 1 and The indwelling guide wire 2 is fixedly connected, and the indwelling guide wire 2 and the extension guide wire 3 are connected to each other during recovery, and the filter main body 1 can shrink to the inside of the recovery sheath 4 .

[0030] In this embodiment, the filter main body is recovered mainly by connecting the extension guide wire with the indwelling guide wire, so that the filter main body shrinks to the inside of the recovery sheath, and then the filter main body can be taken out. In the present invent...

Abstract

The invention provides a recyclable blood vessel filter component. The recyclable blood vessel filter component comprises a guide-in system and a recovery system. The guide-in system comprises a filter body and a retention guide wire, the recovery system comprises a lengthened guide wire and a recovery sheath, the filter body is fixedly connected with the retention guide wire, and during recovery, the retention guide wire is connected with the lengthened guide wire, and the filter body can retract back into the recovery sheath. The recyclable blood vessel filter component is simple in structure and convenient to use and recover and has a long recovery time window.

Description

technical field [0001] The invention relates to a blood vessel filter, in particular to a retrievable blood vessel filter assembly applied to the superior and inferior vena cava with long recovery time. Background technique [0002] The vena cava filter is mainly used to treat pulmonary embolism (referred to as pulmonary embolism, pulmonary embolism, PE). PE is a common disease. The pathogenesis is that peripheral deep venous thrombosis or thrombus in the right heart cavity enters the pulmonary circulation, blocks the pulmonary artery or its branches, and then causes a series of clinical pathophysiological changes mainly caused by pulmonary circulation dysfunction. The results of the study showed that the emboli that caused PE mainly came from the deep veins of limbs or pelvic veins, accounting for 60-90% of the emboli. The thrombus breaks off and returns to the heart along the vena cava system, eventually causing pulmonary embolism. The occurrence of PE is usually not act...
