LACbes左心耳封堵器研发历程与展望

Research history and prospect of LACbes left atrial appendage occluder

LACbes封堵器是我国自主创新研发的左心耳专用封堵器之一,历经外观设计、倒刺研发、定型及动物实验、上市前临床研究等阶段,于2019年上市。LACbes封堵器由远端固定盘、近端覆盖盘和中间连接铆组成,可反复回收不形变,易于操作,适合绝大多数形态的左心耳,目前正在国内推广应用。本文就LACbes封堵器研发历程、创新点、应用要点和展望进行介绍。

LACbes occluder is one of the left atrial appendage devices that are independently innovated and developed in China.This device has gone through all research and development phases,including appearance design,barb research and development,design finalization,animal testing,premarketing clinical research,etc.In 2019 the LACbes occluder products entered the medical market.The LACbes occluder is composed of a distal anchoring lobe and a proximal sealing disc,which are connected by an articulated waist.The LACbes occluder can be repeatedly retrieved with no distortion,besides,it is easy to operate and is suitable for the most forms of left atrial appendage.At present,the LACbes occluder has been promoted and applied in China.This paper introduces the research and development history,the innovation points,the application points and the prospects of LACbes occluder.(J Intervent Radiol,2023,32:710-714)
