Claim 0:
1. A prolapse prevention device for treating valvular regurgitation in a heart valve, the prolapse prevention device comprising:
a continuous wire-like structure having a first end and a second end that opposes the first end, the first end and the second end being disconnected from each other,
wherein the continuous wire-like structure of the prolapse prevention device in a deployed configuration includes
a centering ring configured to seat adjacent to and upstream of an annulus of the heart valve to circumferentially center the prolapse prevention device in situ,
a vertical support extending from the centering ring in an upstream direction such that an apex thereof is configured to seat against the atrium and above the annulus of the mitral valve in situ, wherein the vertical support extends longitudinally and linearly from the centering ring to the roof of the atrium to minimize obstruction within the atrium, and
a leaflet backstop extending radially inward from the centering ring and configured to contact at least a first leaflet of the heart valve in situ to exert a pressure in a downstream direction on the first leaflet to prevent the first leaflet from prolapsing into the atrium.
