発明の名称 (英語) SHOCK WAVE FOCUSING DEVICE, SHOCK WAVE GENERATION APPARATUS, AND SHOCK WAVE ABLATION SYSTEM 新技術説明会
発明の概要(英語) Provided is a shock wave focusing device for a shock wave ablation system for coagulating and necrosing cardiac muscle tissue that becomes a cause of arrhythmia. A shock wave generation apparatus (10) comprises: a shock wave focusing device (11) which has a concave surface (11a); an optical fiber (12) which is inserted into the shock wave focusing device (11); a tubular catheter (13) which guides the optical fiber; an enclosure (14) which constitutes a space to be filled with liquid at the tip of the optical fiber (12); and the liquid (L) which is filled into the enclosure (14). The shock wave focusing device (11) is configured from a ring-shaped coupling part (16) provided with a central hole (11b), and 16 blade parts (17) curved outward from the edge of the coupling part (16) toward the front and provided elastically to the edge of the coupling part (16), and can be folded by rotating the blade parts (17) with respect to the coupling part (16).
