Delivery device of medical device

Abstract

The invention provides a delivery device of a medical device. The delivery device can deliver the medical device to the heart defect part through a catheter, and comprises a first line segment and a second line segment, wherein the first line segment is provided with a near end and a far range part, the second line segment is provided with a first end and a second end, the first end of the second line segment is fixedly connected to the far range part of the first line segment, the second end of the second line segment is provided with a connector for connecting with the medical device, the cross sectional area of the second line segment is smaller than the cross sectional area of the first line segment, so that the second line segment is configured in a manner that when the medical device is delivered to the heart defect part through the delivery device and the heart defect part is closed through withdrawal of the catheter, the second line segment with the flexibility can be connected with the medical device and the disturbing vibration coming from the heart beat can be received, and meanwhile, the medical device can not deviate from the placing position.

Description

technical field [0001] The present invention mainly discloses a delivery device, especially a delivery device for medical equipment, especially a delivery device for delivering a septal defect occluder. Background technique [0002] Congenital heart disease, as the name suggests, is the abnormal structure of the heart that is born with it. That is, the formation of the fetal heart is blocked and caused by abnormal development. According to statistics, approximately seven to ten out of every thousand births suffer from congenital heart disease. Among them, Ventricular Septal Defect (abbreviation: VSD) is the most, atrial septal defect (Atrial Septal Defect, abbreviation: ASD) is second, followed by open ductus arteriosus (Patent Ductus Arteriosus, abbreviation: PDA), Faro Tetralogy of the Fallot (TOF for short), Pulmonary Stenosis (PS for short), and Transposition of the great vessels (Transposition of the great vessels). There are many types of congenital heart disease, a...

Problems solved by technology

However, the interference of the beating of the heart, the rigidity of the blood vessel and the hollow delivery device limit the operating angle of the catheter inside the heart, and the influence of the elastic reaction force of the shutter itself when the shutter is detached from the linker for a moment will cause the shutter to be placed incorrectly. The cause is still unresolved

Furthermore, in order to cooperate with the tether design of the above-mentioned patent, the outer diameter of the hollow delivery device will be larger, and a catheter with a larger outer diameter must be selected correspondingly, which will cause great discomfort to the patient when the catheter passes through the blood vessel of the patient. And the catheter with too large outer diameter is more likely to be affected by the blood vessel, making it difficult to deliver the shutter in the heart
