Valve with delayed leaflet deployment
First Claim
Patent Images
1. A valve, comprising:
- a valve frame;
a valve leaflet coupled to the valve frame, where the valve leaflet includes a commissure at a distal end of the valve leaflet that can reversibly seal for unidirectional flow of a liquid through the valve; and
a biodegradable adhesive between an outer surface of the distal end of the valve leaflet and the valve frame that holds at least the commissure of the valve leaflet in an open position for a predetermined time of no less than one week after implantation into a lumen of a body;
wherein the valve leaflet in the open position is in a static relationship relative the valve frame for the predetermined amount of time.

Abstract
A valve for use in a body lumen, where the valve includes a valve leaflet with delayed leaflet deployment relative an in vivo implant time. The valve includes a valve frame, a valve leaflet coupled to the valve frame. The valve leaflet includes a commissure that can reversibly seal for unidirectional flow of a liquid through the valve, and a biodegradable adhesive between the valve leaflet and the valve frame to hold at least the commissure of the valve leaflet in a static relationship relative the valve frame for a predetermined time once implanted in vivo.

8. A valve, comprising:
-
a valve frame; a valve leaflet coupled to the valve frame, where the valve leaflet includes a commissure at a distal end of the valve leaflet that can reversibly seal for unidirectional flow of a liquid through the valve and an anti-thrombogenie coating; and a biodegradable adhesive between an outer surface of the distal end of the valve leaflet and the valve frame that holds at least the commissure of the valve leaflet in an open position for a predetermined time of no less than one week after implantation into a lumen of a body; wherein the valve leaflet in the open position is in a static relationship relative the valve frame for the predetermined time.

9. A system, comprising:
-
an elongate delivery catheter; and a valve positioned at least partially over the elongate delivery catheter, where the valve includes; a valve frame having frame members defining a lumen; a valve leaflet attached to a portion of the valve frame, the valve leaflet having a commissure at a distal end of the valve leaflet; and a biodegradable adhesive between an outer surface of the distal end of the valve leaflet and the valve frame that holds at least the commissure of the valve leaflet in an open position for a predetermined time of no less than one week after implantation into a lumen of a body; wherein the valve leaflet in the open position is in a static relationship relative the valve frame for the predetermined amount of time. - View Dependent Claims (10, 11, 12, 13)
