AI Technical Summary
Existing blood-direct contact ventricular assist devices have issues with blood compatibility and poor compression effectiveness after cardiac remodeling, while non-blood-direct contact devices have low production efficiency, high cost, and long customized production cycles.
A ventricular assist device was designed, comprising a compression bag and an adjustment bag. The position of the compression bag is adjusted after cardiac remodeling to ensure close contact with the outer wall of the heart. The injection and extraction of the medium are achieved through a delivery catheter and a control device to ensure compression effect and standardized production.
This technology enables the compression bag to fit snugly against the outer wall of the heart after cardiac remodeling, reducing production costs, improving production efficiency, reducing patient waiting time, and lowering the risk of disability and death.
