Impact wave cardiac valve interventional treatment delivery system

Abstract

The invention discloses an impact wave cardiac valve interventional treatment delivery system. The delivery system comprises an outer braided tube of a hollow structure, an inner tube of a hollow structure and a conducting electrode cable, wherein the inner tube is located in the outer braided tube, and a prefabricated channel is formed between the inner tube and the outer braided tube; the conducting electrode cable extends in the prefabricated channel and is used for conducting voltage / current pulses. Through the delivery system, an impact device for treating cardiac valve calcification transmits energy and transforms the energy to an impact wave transmitter, valvular stenosis and reflux stiff valve leaflets or valvular annuli are softened, the opening and closing states of the valve leaflets during work are improved, the treatment effect is achieved, and the intraoperative and postoperative risks of artificial valve implantation can be avoided. The system can be combined with existing operative treatment, the problem is solved that in the operative process, due to serious valve calcification, a cardiac valve cannot be precisely placed, the risks are effectively avoided that in the operative process, the artificial valve is difficult to position and fix, and the artificial valve is improperly released and difficultly taken out, and perivalvular leakage can be reduced.

Description

technical field [0001] The application belongs to the field of medical technology, and in particular relates to a delivery system for shock wave heart valve interventional therapy. Background technique [0002] Cardiac valve calcification is the main pathological manifestation of heart valve stenosis and regurgitation, which usually occurs in the elderly; vascular calcification is a common symptom of atherosclerosis, hypertension, diabetic vascular disease, vascular injury, chronic kidney disease and aging. Pathological manifestations. [0003] At present, the treatment methods for heart valve calcification and vascular calcification include: drug therapy, surgical replacement or interventional replacement and other methods. [0004] The inventors of the present application have discovered in the long-term research and development process that the effect of existing drug therapy is very limited, and the existing surgical or interventional replacement methods have the disadv...
