Implantable valve device
Valve devices, methods of making valve devices, and methods of treating various venous-related conditions, disorders and/or diseases are described. In one embodiment, a valve device includes an expandable support frame and a bioprosthetic valve attached to the support frame. The bioprosthetic valve comprises a leaflet and a contiguous wall portion harvested from a multi-leaflet xenogeneic valve. The contiguous wall portion includes the attachment region where the leaflets attaches to the vessel wall and, in some embodiments, includes the natural margins of attachment between the leaflet and vessel wall.
1. A support frame for implantation in a recipient vessel, said support frame having a longitudinal axis and comprising:
a first connector segment, a second connector segment, and a third connector segment, the first connector segment disposed substantially opposite the second connector segment with respect to said longitudinal axis, the first connector segment and the second connector segment substantially parallel to each other, the third connector segment disposed circumferentially between the first connector segment and the second connector segment with respect to said longitudinal axis, the third connector segment defining an outwardly-projecting curve extending away from the longitudinal axis; and
a proximal portion and a distal portion, the proximal portion and the distal portion connected by the first connector segment, the second connector segment, and the third connector segment;
wherein the outwardly-projecting curve extends from the proximal portion toward the distal portion and away from the longitudinal axis when implanted in said recipient vessel.
2. The support frame of claim 1 , wherein the outwardly-projecting curve creates a sinus region when implanted in said recipient vessel.
3. The support frame of claim 1 , further comprising a window portion free of a connector segment, the window portion disposed between the first connector segment and the second connector segment; and
wherein the window portion is disposed substantially opposite the third connector segment.
4. The support frame of claim 1 , wherein the third connector segment is disposed in a plane that contains the longitudinal axis.
5. The support frame of claim 1 , wherein the proximal portion comprises a closed circumference; and
wherein the distal portion comprises a closed circumference.
6. The support frame of claim 1 , wherein the proximal portion and the distal portion comprise consecutively attached ring members.
7. The support frame of claim 1 , wherein the first connector segment, the second connector segment, and the third connector segment are formed of a cobalt chromium alloy.
8. The support frame of claim 1 , wherein the first connector segment, the second connector segment, and the third connector segment are formed from a flat wire.
9. The support frame of claim 1 , wherein the first connector segment, the second connector segment, and the third connector segment are formed from a single piece of material.
10. A support frame for implantation in a recipient vessel, said support frame having a longitudinal axis and comprising:
a first connector segment, a second connector segment, and a third connector segment, the first connector segment disposed substantially opposite the second connector segment with respect to said longitudinal axis, the first connector segment and the second connector segment substantially parallel to each other, the third connector segment disposed circumferentially between the first connector segment and the second connector segment with respect to said longitudinal axis, the third connector segment defining an outwardly-projecting curve extending away from the longitudinal axis; and
a proximal portion and a distal portion, the proximal portion and the distal portion connected by the first connector segment, the second connector segment, and the third connector segment;
wherein outwardly-projecting curve extends from the distal portion toward the proximal portion and away from the longitudinal axis when implanted in said recipient vessel.
11. The support frame of claim 10 , wherein the outwardly-projecting curve creates a sinus region when implanted in said recipient vessel.
12. The support frame of claim 10 , further comprising a window portion free of a connector segment, the window portion disposed between the first connector segment and the second connector segment; and
wherein the window portion is disposed substantially opposite the third connector segment.
13. The support frame of claim 10 , wherein the third connector segment is disposed in a plane that contains the longitudinal axis.
14. The support frame of claim 10 , wherein the proximal portion comprises a closed circumference; and
wherein the distal portion comprises a closed circumference.
15. The support frame of claim 10 , wherein the proximal portion and the distal portion comprise consecutively attached ring members.
16. The support frame of claim 10 , wherein the first connector segment, the second connector segment, and the third connector segment are formed of a cobalt chromium alloy.
17. The support frame of claim 10 , wherein the first connector segment, the second connector segment, and the third connector segment are formed from a flat wire.
18. The support frame of claim 10 , wherein the first connector segment, the second connector segment, and the third connector segment are formed from a single piece of material.
