Shock wave device for treating cardiac valve calcification

Abstract

The invention discloses a shock wave device for treating cardiac valve calcification. The shock wave device includes: a shock wave generator which generates voltage / current pulses, a shock wave emitter which includes an electrode cable and an electrode probe, a conduction system, a conduction electrode, a balloon and a developing piece, wherein the electrode cable receives and conducts voltage / current pulses and the electrode probe receives the voltage / current pulses to generate a shock wave; the conduction electrode is located inside the conduction system to conduct the voltage / current pulses generated by the shock wave generator to the shock wave emitter; the balloon wraps the shock wave emitter and has a through hole into which an electrolyte liquid flows; and the developing piece is located on the shock wave emitter and / or the balloon. The shock wave generated by the shock wave emitter is transmitted to an area to be treated through the electrolyte liquid in the balloon, and acalcification part softens under the action of the shock wave energy, so that the opening and closing state of a valve leaflet during work is improved, and the purposes of treating calcification, benefiting the cardiac valve release, performing accurate positioning, enabling the periphery to attach to blood vessels and reducing peripheral leakage are achieved.

Description

technical field [0001] The application belongs to the field of medical technology, and in particular relates to a shock wave device for treating heart valve calcification. 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 disadvantages o...
