Replacement Cardiac Valves And Methods Of Use And Manufacture

Abstract

Prosthetic mitral valves and their methods of manufacture and use.

1 . A replacement mitral valve, comprising:
 an anchor frame extending along a longitudinal axis and having a central opening, the anchor frame comprising:
 a flared first anchor having a first plurality of interconnected arcuate portions extending around an outer perimeter thereof, at least some of the first plurality of interconnected arcuate portions including a hook; 
 a second anchor; and 
 a central portion, the flared first anchor is flared radially outward relative to the central portion when the replacement valve is in an expanded configuration; 
   a strut frame secured to the anchor frame; and   a plurality of leaflets attached to the strut frame;   wherein the replacement mitral valve is configured to self-expand from a collapsed configuration to the expanded configuration.   
     
     
         2 . The replacement mitral valve of  claim 1 , wherein each of the plurality of interconnected arcuate portions includes a hook. 
     
     
         3 . The replacement mitral valve of  claim 1 , wherein the hook extends from a tip of the interconnected arcuate portion. 
     
     
         4 . The replacement mitral valve of  claim 3 , wherein the hook extends inward from the tip of the interconnected arcuate portion. 
     
     
         5 . The replacement mitral valve of  claim 3 , wherein the hook extends towards the central opening when the replacement mitral valve is in the expanded configuration. 
     
     
         6 . The replacement mitral valve of  claim 1 , wherein tips of the arcuate portions are rounded. 
     
     
         7 . The replacement mitral valve of  claim 1 , wherein the second anchor comprises an atrial anchor. 
     
     
         8 . The replacement mitral valve of  claim 7 , wherein the atrial anchor comprises a plurality of atrial cells. 
     
     
         9 . The replacement mitral valve of  claim 8 , wherein the atrial anchor is flared radially outward relative to the central portion. 
     
     
         10 . The replacement mitral valve of  claim 9 , wherein at least some of the atrial cells include an aperture at a bend near an end portion. 
     
     
         11 . The replacement mitral valve of  claim 7 , wherein the atrial anchor is formed of a material that is thinner as compared to the central portion. 
     
     
         12 . The replacement mitral valve of  claim 1 , wherein the strut frame is attached to a central portion of the anchor frame. 
     
     
         13 . The replacement mitral valve of  claim 1 , wherein the strut frame is indirectly attached to the anchor frame. 
     
     
         14 . The replacement mitral valve of  claim 1 , wherein the flared first anchor is a ventricular anchor. 
     
     
         15 . The replacement mitral valve of  claim 1 , wherein the second anchor is formed of a material that is thinner as compared to the flared first anchor.
