Problems solved by technology

[0003] However, at present, due to factors such as calcification, stenosis, and adhesion of rheumatic lesions in the aortic root of the elderly, the placement of the artificial valve may not be possible, resulting in the failure of the operation. Incidence of central leak, paravalvular leak, and arrhythmia

Abstract

The invention relates to the field of transcatheter aortic valve replacement (TAVR) technologies, and discloses a novel split type absorbable artificial interventional heart valve system. The tail endof a delivery catheter is provided with a self-expansion expanding part, a balloon expanding part is arranged on the lower portion of the self-expansion expanding part, a component A loading part anda component B loading part are arranged outside the delivery catheter from left to right, a component A is loaded outside the component A loading part, and a component B is loaded outside the component B loading part. The split type absorbable artificial interventional heart valve system has the advantages that an artificial heart valve can be accurately released, the service life is long and thelike, the occurrence rate of valve center leakage, valve periphery leakage and arrhythmia after a TAVR operation can be reduced, and meanwhile the defect that a patient cannot accept coronary stent implantation (PCI) treatment after an existing artificial heart valve replacement operation is overcome; and meanwhile, the TAVR operation can be suitable for more patients with poor peripheral blood vessels.

Description

technical field [0001] The invention relates to the technical field of heart valve replacement through catheter intervention, in particular to a novel split-type, absorbable artificial heart valve system. Background technique [0002] Aortic stenosis is a common heart structural disease in the elderly, and its incidence increases with age. Among people ≥65 years old, the incidence of AS is about 2%. Surgical thoracotomy for aortic valve replacement is an effective treatment for severe AS, but about 1 / 3 of patients cannot accept SAVR due to advanced age, physical weakness or other factors. Transcatheter aortic valve replacement uses the minimally invasive technique of cardiac interventional catheters to perform artificial interventional heart valve replacement. It has the advantages of no thoracotomy, low risk, simple operation, small trauma, quick recovery and few complications, and is especially suitable for surgical patients. Surgical contraindications or high-risk patien...
