AI Technical Summary
In existing technologies, transcatheter heart valves (THVs) are difficult to fully expand and fix in larger natural valves or implantation sites, especially pulmonary valves, which have large geometric variations, making replacement difficult.
An expandable docking station frame was designed, comprising multiple support sections forming a continuous curved longitudinal profile, with an outer radial holding section and an inner radial central section. It can adapt to blood vessels of different sizes in the expanded state, and combined with impermeable materials to provide a seal, enabling accurate positioning and fixation of valves via a delivery catheter.
It enables stable expansion and fixation of THV in large implantation sites such as the pulmonary artery, improving the success rate and safety of valve replacement and adapting to the differences in anatomical structure among different patients.
