Central shunt

Abstract

The central shunt made of metal net has umbrella shaped ends and tubular middle part. It is used for intervening treatment or operative treatment of complex congenital heart disease to shunt aorta from pulmonary artery, to shunt left pulmonary artery from right pulmonary artery, or to maintain the constant opening diameter of the ductus arteriosus. It may be also used for various kinds of artery-vein fistulation and anastomosing adjacent blood vessels.

Description

Technical field [0001] The present invention relates to a kind of umbrella-shaped two ends and tubular center made of metal mesh, which is used for shunting aorta and pulmonary artery, left or right pulmonary artery; Open with constant diameter; it can also be used for various arteriovenous ostomy and anastomosis between adjacent blood vessels. . Background technique [0002] At present, known various occluding umbrellas can only be used to occlude intracardiac defects, and central shunt can only be realized by various operations. There is no effective central shunt that can be achieved both by surgery and by intervention. Also, keeping the ductus arteriosus patent with drugs is neither safe nor sure. Surgical implementation of central shunt is riskier. Contents of the invention [0003] In order to overcome the shortcomings of existing interventions that cannot achieve central shunt and complicated surgical operations, the central shunt can be directly deployed during...
