Problems solved by technology

[0005] One of the solutions in the existing technology is to implant an atrial shunt device, but there are very few delivery devices specially used for the atrial shunt at present. Therefore, it is necessary to improve this to overcome the deficiencies in practical applications

Embodiment 1

[0039] Such as Figure 1-8 As shown, the delivery system 100 of the atrial shunt of this embodiment can help the atrial shunt 104 to pass through the "transseptal technique" technique (that is, insert the catheter into the right femoral vein, go up the inferior vena cava and enter the right atrium. Then insert the septum puncture and the catheter is passed into the left atrium) and sent to the atrial septum 105 for atrial decompression.

[0040] Specifically, the delivery system 100 of an atrial shunt is composed of a first sheath structure 101, a second sheath structure 102, and an inner core tube structure 103. The second sheath structure 102 is connected with the first sheath structure 101 and the inner core tube structure 103. A sheath structure 101 is used to puncture and ream the atrial septum, a second sheath structure 102 is used to constrict the atrial shunt 104, and the inner core tube structure 103 is connected to the atrial shunt 104 so that the atrial shunt 104 ca...

Embodiment 2

[0058] A delivery system for an atrial shunt in this embodiment differs from Embodiment 1 in that:

[0059] In this example, an atrial shunt catcher is added to the inner core tube structure 103, which can be used to help recover and replace the atrial shunt 104, and the catcher adopts a clamping method to catch and fix the atrial shunt 104.

[0060] For other specific structures and specific implementation steps, please refer to Embodiment 1.

Embodiment 3

[0062] A delivery system for an atrial shunt in this embodiment differs from Embodiment 1 in that:

[0063] In this example, the inside of the inner core tube 132 is changed to be hollow, and the wire harness end of the atrial shunt is loaded into the inner core tube 132 by hydraulic suction, and the atrial shunt 104 is released by liquid mechanical pressurization at the tail of the inner core tube 132 .

[0064] For other specific structures and specific implementation steps, please refer to Embodiment 1.

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a delivery system for an atrial shunt. The delivery system comprises a first sheath structure, a second sheath structure and an inner core tube structure, the second sheath structure is connected with the first sheath structure and the inner core tube structure, the first sheath structure is used for puncturing and reaming an atrial septum, the second sheath structure is used for collecting the atrial shunt, and the inner core tube structure is connected with the atrial shunt, so that the atrial shunt reaches the atrial septum and is released. The delivery system for the atrial shunt can be helped to be implanted into the human body, the surgery success rate and the surgery operation convenience are improved, the atrial shunt can be implanted only by passing through the femoral vein, then passing through the heart diaphragm and then operating the delivery system, damage to a patient is small, and the service life of the patient is effectively helped to be prolonged.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a delivery system for an atrial shunt. Background technique [0002] Heart failure (heart failure) referred to as heart failure refers to the failure of the venous blood to fully discharge the heart due to the dysfunction of the systolic function and / or diastolic function of the heart, resulting in blood stasis in the venous system and insufficient blood perfusion in the arterial system, resulting in Cardiac circulatory disorder syndrome, which is characterized by pulmonary congestion and vena cava congestion. Heart failure is not an independent disease, but the end stage of the development of heart disease. The vast majority of heart failures begin with left heart failure, that is, the first manifestation is pulmonary circulation congestion. [0003] Heart failure is mostly characterized by decreased cardiac output. In this setting, the main clinical manif...
