  • Publication number: 20170079784
    Abstract: An implantable prosthetic valve has an in situ formable support structure. The valve comprises a prosthetic valve, having a base and at least one flow occluder. A first flexible component is incapable of retaining the valve at a functional site in the arterial vasculature. The first component extends proximally of the base of the valve. A second flexible component is incapable of retaining the valve at a functional site in the arterial vasculature. The second component extends distally of the base of the valve. At least one rigidity component combines with at least one of the first and second flexible components to impart sufficient rigidity to the first or second components to retain the valve at the site.

  • Patent number: 9572661
    Abstract: A method for reducing an axial profile of a valve implant includes providing a valve implant having a longitudinal axis and a delivery catheter having a central axis and a distal receiving section. The method further includes helically rolling the valve implant around a rolling axis that is offset at an angle of about 15 degrees to about 60 degrees with respect to the longitudinal axis to form a rolled valve implant having a rolled axis, where the rolled axis is the same as the rolling axis. The method further includes aligning the rolled axis of the rolled valve implant with the central axis of the delivery catheter. The method further includes inserting the rolled valve implant into the distal receiving section of the delivery catheter.

  • Publication number: 20120277855
    Abstract: An implantable prosthetic valve for a human heart is disclosed. The prosthetic valve has an inflatable tubular annular support structure and at least one moveable occluder that controls the flow of blood through the support structure. The support structure has a flow control valve configured for coupling to an inflation lumen for inflating the support structure with an inflation media. The flow control valve seals after decoupling from the inflation lumen and prevents the inflation media from escaping.
