Problems solved by technology

[0004] In the prior art, the shunt stent is compressed and transported into the human body through a delivery device. Due to the complex physiological mechanism of the human body, the delivery catheter is usually unable to adapt to the individual physiological and anatomical structure, resulting in difficult positioning of the delivery device and inaccurate release. At the same time, during the implantation process, once problems such as positioning deviation are found, the adjustment of the delivery device is often very difficult, and the doctor's operation requirements are extremely high. Various additional operations will prolong the patient's exposure time to X-rays, which is not conducive to the patient's health.

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a conveying device of an atrial septum flow divider which comprises an inner core tube assembly, an inner sheath tube, an outer sheath tube and a handle; the outer sheath tube is connected with the handle, the inner core tube assembly is slidably matched with the inner sheath tube, the inner sheath tube is slidably matched with the outer sheath tube, and the near end of the inner core tube assembly and the near end of the inner sheath tube are connected with the handle; the handle is used for conveying the flow divider into the atrial septal stoma by adjusting the forward and backward feeding of the inner core tube assembly and the inner sheath tube and the bending degree of the outer sheath tube; according to the conveying device, the conveying position can be adjusted at any time so as to improve the positioning precision, and the flow divider is accurate in release and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a delivery device for an atrial septal shunt. Background technique [0002] Heart failure (HF) is a group of syndromes caused by various structural or functional diseases of the heart that lead to impaired ventricular filling and / or ejection ability. [0003] At present, most heart failures start with left heart failure, that is, the first manifestation is pulmonary circulation congestion. For chronic heart failure caused by continuous high pressure in the left atrium, the usual solution is to implant the interatrial septum between the left atrium and the right atrium. A shunt device that redistributes the volume of blood in the atria and reduces interatrial pressure imbalances. [0004] In the prior art, the shunt stent is compressed and transported into the human body through a delivery device. Due to the complex physiological mechanism of the human body, t...
