Prosthetic Valve With Vortice-Inducing Baffle
First Claim
1. A prosthetic valve having an inflow end opposite an outflow end, the prosthetic valve comprising:
- a stent frame defining a lumen;
a valve structure disposed within the lumen and configured to define an inflow side and an outflow side opposite the inflow side;
wherein an outflow track is established within the lumen downstream of the outflow side and along which fluid flow from the valve structure progresses; and
a baffle structure connected to the stent frame downstream of the outflow side and configured to induce vortical flow.

Abstract
A prosthetic valve comprising a stent frame, a valve structure, and a baffle structure. The stent frame defines a lumen. The valve structure is disposed within the lumen, and defines an inflow side and an outflow side. An outflow track is established within the lumen downstream of the outflow side and along which fluid flow from the valve structure progresses. The baffle structure is connected to the stent frame downstream of the outflow side and is configured to induce vortical flow, for example including a vortex ring. In some embodiments, the prosthetic valve is a transcatheter prosthetic mitral valve having three leaflets.

16. A method of regulating fluid flow through a body vessel of a patient, the method comprising:
-
implanting a prosthetic valve within the body vessel, the prosthetic valve having an inflow end opposite an outflow end and including; a stent frame defining a lumen, a valve structure disposed within the lumen and configured to define an inflow side and an outflow side opposite the inflow side, wherein an outflow track is established within the lumen downstream of the outflow side and along which fluid flow from the valve structure progresses, a baffle structure connected to the stent frame downstream of the outflow side and configured to induce vortical flow; wherein fluid flow within the body vessel is naturally directed to the inflow side; and further wherein the valve structure functions to alternately allow and occlude fluid flow from the inflow side to the outflow side; and even further wherein the baffle structure functions to induce vortices into blood flow from the outflow side to the outflow end. - View Dependent Claims (17, 18, 19, 20, 21)
