Controllably deployable prosthetic valve

A prosthetic valve comprising:

• a radially expandable frame comprising an atrial flange, a ventricular skirt, an annular region, and a ventricular anchor tab, wherein the atrial flange is disposed on one end of the expandable frame and the ventricular skirt is disposed on an opposite end of the expandable frame,
• wherein the annular region is disposed between the atrial flange and the ventricular skirt,
• wherein the ventricular anchor tab is coupled to the ventricular skirt;
• and
• a straitjacket disposed around a perimeter of the atrial flange and configured to apply a hoop force to the expandable frame thereby controlling an amount of expansion or an amount of collapse of the expandable frame, wherein the straitjacket is disposed over the ventricular anchor tab and the ventricular skirt, wherein adjustment of the hoop force controls a radial distance between the ventricular anchor tab and the ventricular skirt, wherein the straitjacket comprises a first free end that comprises a slot and a second free end opposite the first free end, the second free end comprising an eyelet protruding outward and disposed in the slot,
• wherein, when a tether is releasably and slidably disposed in the eyelet, the straitjacket is held in a closed loop that constrains expansion of the atrial flange, and
• wherein removal of the tether from the eyelet allows the straitjacket to open and permit expansion of the atrial flange.

A prosthetic valve, comprising:

• a radially expandable frame comprising an atrial flange, a ventricular skirt, an annular region disposed between the atrial flange and the ventricular skirt, a ventricular anchor tab, and a plurality of commissure posts,
• wherein the atrial flange is disposed on one end of the expandable frame and the ventricular skirt is disposed on an opposite end of the expandable frame,
• wherein the ventricular skirt has a ventricular edge that is a downstream-most edge of the prosthetic valve,
• wherein the ventricular anchor tab is coupled to the ventricular skirt, and
• wherein the plurality of commissure posts comprises a free end and a connected end, the connected end coupled to the expandable frame, and wherein the free end extends beyond the ventricular edge of the ventricular skirt;
• and a straitjacket disposed around a perimeter of the atrial flange and configured to apply a hoop force to the expandable frame, thereby controlling an amount of expansion or an amount of collapse of the expandable frame, wherein the straitjacket comprises a first free end that comprises a slot and a second free end opposite the first free end, the second free end comprising an eyelet protruding outward and disposed in the slot, wherein, when a tether is releasably and slidably disposed in the eyelet, the straitjacket is held in a closed loop that constrains expansion of the atrial flange, and wherein removal of the tether from the eyelet allows the straitjacket to open and permit expansion of the atrial flange.
