1. A valve, comprising:
- a valve frame having a distal end and a proximal end, and frame members defining an lumen;
a valve leaflet having a distal end and a proximal end, where a portion of the distal end of the valve leaflet is coupled adjacent to the proximal end of the valve frame; and
a leaflet transition member coupled to at least a portion of the valve leaflet, where the valve leaflet and the leaflet transition member in a first position are at least partially outside the lumen of the valve frame with the proximal end of the valve leaflet extending away from both the distal end and the proximal end of the valve frame, and where the valve leaflet and leaflet transition member transition from the first position to a second position in which the proximal end of the valve leaflet and at least a portion of the leaflet transition member are within the lumen of the valve frame.

Abstract
Apparatus, systems, and methods for percutaneous valve replacement and/or augmentation are provided. The apparatus includes a valve having a valve frame, a valve leaflet coupled to the valve frame, and a leaflet transition member coupled to the valve leaflet. The valve leaflet and leaflet transition member can transition from a first position where the valve leaflet and leaflet frame are at least partially outside a lumen of the valve frame to a second position where the valve leaflet and the leaflet transition member are within the lumen of the valve frame.

8. A method for deployment of a valve, comprising:
-
radially expanding a valve frame of the valve from a delivery state to a deployed state; and transitioning a leaflet transition member coupled to a valve leaflet in a first position outside a lumen of the valve frame to a second position inside the lumen of the valve frame. - View Dependent Claims (9, 10, 11)

12. A system, comprising:
-
an elongate delivery catheter; an expandable balloon positioned around at least a portion of the elongate delivery catheter; a retractable sheath positioned around at least a portion of the elongate delivery catheter, where the retractable sheath moves longitudinally relative the elongate delivery catheter; and a valve, where a portion of the valve is positioned between the elongate delivery catheter and the retractable sheath, and where the valve includes a valve frame having frame members defining a lumen, a valve leaflet attached to a portion of the valve frame, and a leaflet transition member attached to at least a portion of the valve leaflet, where the valve leaflet and leaflet transition member extend away from the lumen of the valve frame in a first position and transition into a second position in which the valve leaflet and leaflet transition member are inside the lumen of the valve frame. - View Dependent Claims (13, 14, 15, 16, 17, 18)
