Publication number: 20220008233Abstract: Described herein are artificial valves that have a frame and leaflets that grow or expand with a patient. Upon placing the valve inside the patient, the valve expands as the annulus of the patient expands. The frame of the valve is configured to expand which in turn causes the leaflets to expand (e.g., to grow). The valve includes a thin undulating wire embedded inside the leaflets. As the annulus of the patient grows, the frame expands, and as the frame expands, the leaflets grow. The growth or expansion of the leaflets is configured so that the valve continues to operate properly (e.g., the leaflets continue to coapt) with expansion of the annulus. The change in size of the valve can be configured to accommodate changes in size of the annulus from an infant or child to an adult.Type: ApplicationFiled: September 24, 2021Publication date: January 13, 2022Inventors: Nima V. Nia, Hengchu Cao, Sakyasingh Tripathy, Douglas Thomas Dominick, Bingquan Su, Behnood Miri, Zahra Moyedi
