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, wherein 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; and
at least one mechanical member engaged to the leaflet transition member,wherein, in a first position, the valve leaflet and the leaflet transition member 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,wherein the valve leaflet and the 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, andwherein, in the second position, the at least one mechanical member is coupled to 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 deliver state to a deployed state; 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; and coupling, in the second position, at least one mechanical member to the valve frame, wherein the at least one mechanical member is engaged to the leaflet transition member. - View Dependent Claims (9, 10)

11. 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, wherein the retractable sheath moves longitudinally relative the elongate delivery catheter; and a valve, wherein a portion of the valve is positioned between the elongate delivery catheter and the retractable sheath, and wherein the valve comprises; 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, wherein 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; and at least one mechanical member engaged to the leaflet transition member, wherein, in a first position, the valve leaflet and the leaflet transition member 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, wherein the valve leaflet and the 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, and wherein, in the second position, the at least one mechanical member is coupled to the valve frame. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
