Reaming type non-implanted atrium shunting device

Abstract

The invention relates to the technical field of medical equipment, in particular to a reaming type non-implanted atrium shunting device. The reaming type non-implanted atrium shunting device comprises a catheter component, a radio frequency component which is arranged on the end portion, stretching into the human body, of the catheter component, and a radio frequency ablation apparatus which is arranged at the other end of the catheter component and is connected with the radio frequency component; after the radio frequency component stretches into a puncture hole, the radio frequency ablation apparatus releases radio frequency energy, and the radio frequency component ablates the hole wall of the puncture hole. The radio frequency component is sent to the position of a puncture hole, when the radio frequency ablation apparatus releases energy, the radio frequency component can enable human tissue to generate heat, the atrial septum at the target position is ablated to form a hole with a fixed size, and therefore the purpose of hole forming is achieved. The radio frequency component is used for forming holes in a radio frequency mode, the formed holes are not prone to being closed again, blood of the left atrium can be effectively drained into the right atrium through hole forming, the pressure of the left atrium is reduced, and the purpose of treatment is achieved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a reaming type non-implantation atrial shunt device. Background technique [0002] Heart failure is a common and potentially fatal disease in humans. Although hospitals try their best to treat it, it is often difficult to control and cure it clinically. In particular, "heart failure with preserved ejection fraction (HFpEF)" has seen a marked increase in prevalence over the past few years, but its treatment remains a challenge for clinicians. [0003] Heart failure with preserved ejection fraction is a concept of heart failure proposed relative to systolic insufficiency, mainly referring to heart failure that occurs when left ventricular diastolic function is reduced and systolic function is relatively normal. The disease is characterized by left ventricular stiffness with reduced compliance and impaired relaxation, resulting in elevated end-diastolic pressure. About o...
