Abstract

The invention discloses an atrial shunt conveying device. The atrial shunt conveying device is provided with a catheter sheath structure, wherein the catheter sheath structure is provided with a pre-bent sheath tube and a catheter sheath handle, wherein the far section of the pre-bent sheath tube is bent; the catheter sheath handle is communicated with the near end of the pre-bent sheath tube and is provided with a hollow cylindrical main body; a sealing gasket with a needle hole is arranged in the cylindrical main body and is provided with a flat sealing gasket and a bent sealing gasket; the bent sealing gasket is tightly attached to the flat sealing gasket. According to the atrial shunt conveying device, the bent sealing gasket in the conventional catheter sheath handle is adjusted into a double-layer sealing gasket, the thickness of each layer of sealing gasket is only half of that of the sealing gasket in the prior art, the sealing gasket close to the near end is changed into a planar sealing gasket, and the sealing gasket at the far end is still bent. The bending amplitude, namely the curvature radius, is adjusted, so that the passing easiness and the sealing property can be guaranteed after an instrument passes through the atrial shunt conveying device. The flat sealing gasket guarantees the sealing property when no instrument passes through the atrial shunt conveying device.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an atrial shunt delivery device. Background technique [0002] Heart failure (Heart Failure), referred to as heart failure, is a common manifestation of cardiomyopathy caused by various reasons. According to current guidelines, heart failure can be divided into three categories: heart failure with reduced ejection fraction (HFrEF), heart failure with median ejection fraction (HFmrEF), and heart failure with preserved ejection fraction (HFpEF). [0003] Among them, HFpEF refers to heart failure with an ejection fraction greater than 50%, which mainly manifests as a decrease in diastolic function and compliance rather than a decrease in systolic function. The existing clinical epidemiological data show that more than half of the hospitalized heart failure patients have HFpEF or HFmrEF, and HFpEF and HFrEF have similar long-term mortality and complication rates. The incide...
