Abstract

The invention discloses a delivery system of a ventricular volume reduction device. The delivery system comprises a mandrel, an outer sleeve and an operating handle; the ends, away from the operatinghandle, of the mandrel and the outer sleeve are both used for being connected with the ventricular volume reduction device; the periphery of the outer sleeve is further sleeved with a conveying sheathand a loader; one end, close to the operating handle, of the conveying sheath is connected with the loader; a shaft hole is formed in the outer sleeve in the axial direction of the outer sleeve in apenetrating mode, and the mandrel is arranged in the shaft hole in a penetrating mode; the periphery of the end, away from the operating handle, of the outer sleeve is sleeved with an expandable bag body; the outer sleeve is provided with a cavity communicating with the interior of the expandable bag body; the cavity is not in communication with the shaft hole; and the outer sleeve is provided with an operation opening communicating with the cavity. According to the delivery system, the expandable bag body is arranged on the outer sleeve, pressure is applied to anchor thorns after the expandable bag body is expanded, reliable anchoring of the anchor thorns and ventricular wall muscles is ensured, and the ventricular volume reduction device is prevented from shifting or falling off.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a delivery system for a ventricular volume reduction device. Background technique [0002] Percutaneous Ventricular Reconstruction (PVR) is a new technique for minimally invasive interventional treatment of ventricular aneurysm and heart failure. This technique is mainly retrograde through the catheter, and a ventricular isolation device is implanted in the left ventricle of the patient to isolate the non-functional ventricular region. , reduce left ventricular systolic and diastolic volumes, reduce left ventricular tension, improve left ventricular remodeling and cardiac function; compared with traditional surgical left ventricular reconstruction, percutaneous ventricular reconstruction (PVR) has the advantages of less trauma and lower safety risks advantage, so its application prospect is broad. [0003] The Chinese invention patent application with the publication num...
