    Abstract: 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.

    IPC: A61B17/04

    Abstract: Some disclosed suture securement devices comprise a flat, thin, generally planar body that has one or more suture engagement slots extending into the body from a perimeter inlet for receiving sutures laterally into the device. The slots can be resiliently widened to receive a suture and then released to clamp onto the suture. Some embodiments include two or more such suture engagement slots that independently receive and secure different sutures. Some embodiments include one or more locking tabs that have a closed position that retains the slots against widening and blocks the inlet to the slot. In some embodiment two or more slots are position next to each other on the same side of the device, while in other embodiments slots are positioned on opposite sides of the device. Other types of suture securement devices are also disclosed.

    Abstract: A low pressure gradient prosthetic heart valve for implant in a human. The valve includes a support frame with undulating inflow cusps and outflow commissure posts to which flexible leaflets attach and coapt in a flow area. The commissure posts angle outward in a neutral state to widen the outflow orifice area. Also, the leaflets are designed to fit within the support frame and expand outward in a valve open state without creating a shelf or belly that would restrict flow.
