Embodiment Construction

[0081] The core idea of ​​the present invention is to provide a filter recovery protection device, including a filter assembly, the filter assembly includes a bag-type filter layer and a fixing structure, the bag-type filter layer has an opposite first distal end and a first proximal end, The first distal end of the bag-type filter layer has an opening, and the opening is used to allow thrombus in the blood vessel to enter the bag-type filter layer when the filter is recovered; the fixing structure is arranged at the first distal end. end and is used to fit the inner wall of the blood vessel.

[0082] The filter recovery protection device is used to be arranged at the proximal end of the filter when the filter is recovered, so as to intercept the thrombus falling from the filter and prevent large-size thrombus from entering the pulmonary artery and causing pulmonary embolism. Moreover, after the filter component intercepts the thrombus, the thrombus can be recovered together w...

Abstract

The invention provides a filter recovery protection device, a filter recovery system and method and a filtering system. The filter recovery protection device comprises a filtering assembly, the filtering assembly comprises a bag type filtering layer and a fixing structure, the bag type filtering layer is provided with a first far end and a first near end which are opposite, the first far end of the bag type filtering layer is provided with an opening, and the opening is used for allowing thrombus in a blood vessel to enter the bag type filtering layer when a filter is recovered; and the fixingstructure is arranged at the first far end and used for being attached to the inner wall of the blood vessel. According to the filter recovery protection device, serious consequences such as pulmonary embolism caused by the reason that thrombus enters pulmonary arteries when the filter is recovered can be avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a filter recovery protection device, a filter recovery system and method, and a filter system. Background technique [0002] Venous thromboembolism (VTE) is a common clinical disease with high morbidity and mortality, including deep vein thrombosis (deep vein thrombosis, DVT) and pulmonary embolism (pulmonary embolism, PE). DVT often occurs in the veins of the lower extremities, while PE is mainly caused by the thrombosis in the venous system or right heart veins and enters the pulmonary artery, which is the main cause of morbidity and death in patients. At present, anticoagulant therapy has been the gold standard for VTE treatment, with the purpose of preventing thrombosis and pulmonary embolism, and maintaining venous patency. When anticoagulant therapy is no longer suitable for patients with anticoagulant contraindications or blood complications, the implantation of a...
