Components of the device:
silicone suction cup; flexible shaft; low-profile collapsible blood flow blocking membrane. - Figure 2
(A) Insertion of the device through the ventricular injury.
Low-profile collapsible blood flow blocking membrane. (B) This figure depicts the device fully deployed. Low-profile collapsible blood flow blocking membrane deployed inside the ventricle sealing the injury. The silicone suction cup positioned against the outer surface of the heart overlying the injury and abutting the blood flow blocking membrane. The flexible shaft. - Figure 3
Intraoperative photograph depicts the new device temporizing hemorrhage in a right ventricular injury in the beating heart. Hemorrhage is controlled without traction to the flexible shaft.
The silicone suction cup is positioned against the ventricle over the site of the injury. The low-profile collapsible blood flow blocking membrane sealing the injury from inside the ventricle (not shown). The flexible shaft.
