Centrifugal process has the function of Quick uniform mixing and drives away bubble in solution simultaneously, and dissolution is abundant and defoams and evenly dispersed effect
It is prominent, it ensure that the quality of production closer.
After the closer is placed to Endovascular by short sheath, the application method of the closer can be summarized as follows: one is moved back
One drawing is further moved back.
One moves back: exiting closer outer tube (3. manipulation epitheca joystick control is completed) makes the closer lower wall of bottom in lumen of vessels
It inside flicks discoid.
One draws: pulling, makes in the disc-shaped opening of Endovascular outward together together with short sheath and connecting line and closer
Lower wall is adjacent to vascular puncture mouth inner wall.
One moves back: exit closer inner tube (manipulation epitheca joystick control 5. complete), turn off on device disk can appliance for releasing single in blood
It is flicked at pipe puncture orifice outer wall, forms the external disk of covering vascular puncture mouth.
Technical indicator
The scope of application: it can be used for the quick-make of caused vascular wall puncture orifice after the short sheath of 5F to 14F punctures.
