Chương 988: This Pie is Too Large

The occluder was inserted into the patient's body via a special long delivery sheath before it expanded, just like a parachute being forced to open inside the heart. 

The difference was that the occluder was in the shape of dumbbells, and its waist in the middle could fit perfectly at the defect at the left and right atria. Both sides had disks, and the size was different between occluders, and the surgeon could choose the size. The small left disk was only 0.6 inch or 0.7 inch, while the big disk was 2.0 inches or 2.1 inches.

When such a big foreign body was put into a heart, there would naturally be some potential complications. However, for patients who already had severe symptoms, this was an easier plan.
