AI Technical Summary

Technical Problem

There is a need for improved transcatheter heart valves and delivery systems that can effectively expand and lock prosthetic valves at the desired implantation site, addressing the limitations of existing mechanically expandable valves.

Method used

The use of clamps and expansion and locking mechanisms, comprising an outer and inner member, that allow the frame to axially foreshorten and radially expand, with side arms that are resiliently expandable and biased inward, coupled to the frame via clamps and fasteners, enabling secure locking and expansion of prosthetic valves.

Benefits of technology

The solution provides a reliable and efficient mechanism for expanding and locking prosthetic valves at the desired diameter, ensuring secure implantation and preventing undesired recompression, thereby enhancing the effectiveness of transcatheter heart valve delivery systems.
