Soft robotic technology has great potential for advancing the performance of transcatheter cardiac devices, due to its inherent properties for conformability and simple actuation. This work provides a proof‐of‐concept tricuspid valve that can be delivered via a catheter and made with soft balloons in order to avoid critical anatomical features in the tricuspid valve and to enhance anchoring. This soft valve is inflatable and thus can be repositioned during delivery to conform and anchor well to the native anatomy. Using a 3D printed model of the tricuspid valve, which is segmented from a patient CT scan, the anchoring force, functionality of the valve, and prevention of paravalvular leakage are demonstrated.
