Delivery device for medical instrument for delivering septal defect occluder without interference vibration from heartbeat to deflect medical instrument from disposed location
The present invention provides a delivery device for medical instrument, which may deliver the medical instrument to the defected location of heart through a catheter and comprises a first segment and a second segment. The first segment has a near end and a far end, and the second segment has a first end and a second end, wherein the first end of the second segment is fixed with the far end of the first segment, and the second end of the second segment is configured with a connector to be connected with the medical instrument. The cross-sectional area of the second segment is less than that of the first segment, so that when the second segment is disposed for closing the heart defect as a medical instrument being delivered to the defected location of heart by the delivery device and then removing the catheter, the flexibility of the second segment may keep the connection with the medical instrument, absorb the interference vibration from the heartbeat, and may not deflect the medical instrument from the disposed location.本發明醫療器材的遞送裝置能夠經導管遞送醫療器材至心臟缺損處並包括第一線段與第二線段,第一線段具有近端與遠端,第二線段具有第一端與第二端,第二線段第一端固定地連接於第一線段的遠端,第二線段的第二端設有連接件能夠連接醫療器材,第二線段的橫截面面積小於第一線段的橫截面面積,使第二線段被配置為當醫療器材藉由遞送裝置送達心臟缺損處並經後撤導管而關閉心臟缺損時,第二線段的柔韌性能夠保持與醫療器材連接並吸收來自心臟跳動的干擾振動,且不會使醫療器材偏離已置放好的位置。10‧‧‧遞送裝置11‧‧‧第一線段111‧‧‧金屬線112‧‧‧彈簧線12‧‧‧第二線段1201‧‧‧第一端1202‧‧‧第二端121‧‧‧連接件122‧‧‧螺紋部13‧‧‧接合件
