Multi-frame prosthetic heart valve

A prosthetic valve comprising:

• one or more leaflets;
• an inner frame having a diameter and operatively supporting the one or more leaflets;
• an outer frame having a diameter that is larger than the diameter of the inner frame, wherein the outer frame comprises a plurality of frame elements defining a plurality of apertures arranged in a plurality of circumferentially extending rows of apertures that extend continuously around the outer frame, wherein opposing first and second ends of the inner frame extend beyond respective, opposing first and second ends of the outer frame, wherein the inner frame defines a plurality of leaflet windows, wherein each leaflet window extends an entire height of the inner frame, from the first end to the second end of the inner frame, wherein each leaflet window has a perimeter defined by frame elements of the inner frame and is without frame elements within the perimeter of the leaflet window, wherein the first end of the inner frame is defined by a first circumferentially extending row of frame elements that zigzag continuously around the first end of the inner frame, and wherein the second end of the inner frame is defined by a second circumferentially extending row of frame elements that zigzag continuously around the second end of the inner frame;
• and
• a film covering the inner frame and the outer frame, a portion of the film extending between the inner frame and outer frame defining a bridge portion coupling the inner frame and the outer frame, the inner frame being nested within the outer frame in a telescoping manner such that the bridge portion defines a first circumferential fold at the second end of the outer frame and a second circumferential fold at the first end of the inner frame, the bridge portion extending between the second end of the outer frame and the first end of the inner frame.

A prosthetic valve comprising:

• a leaflet frame defining three leaflet windows and having a wall defining a cylindrical shape and an open pattern of apertures that allows the leaflet frame to be compressed and expanded between different diameters, wherein the leaflet frame comprises a first circumferentially extending row of frame elements that zigzag continuously around a first end of the inner frame and a second circumferentially extending row of frame elements that zigzag continuously around a second end of the inner frame, wherein each leaflet window is defined by two leaflet window sides, a leaflet window top comprising frame elements of the first circumferentially extending row of frame elements, a leaflet window base comprising frame elements of the second circumferentially extending row of frame elements, and two longitudinally extending posts that are defined by frame elements of the leaflet frame, wherein each post interconnects two adjacent leaflet windows of the three leaflet windows, wherein each post extends between one of the two leaflet window sides and the leaflet window top, and wherein the three leaflet windows extend around a circumference of the leaflet frame;
• an outer frame having a wall defining a tubular shape and an open pattern of apertures that allows the outer frame to be compressed and expanded between different diameters, the leaflet frame being nested within the outer frame, wherein the apertures of the outer frame are arranged in a plurality of circumferentially extending rows of apertures that extend continuously around the outer frame, and wherein the outer frame is shorter than the leaflet frame with a first end of the leaflet frame extending beyond a first end of the outer frame and a second end of the leaflet frame extending beyond a second end of the outer frame in a deployed configuration of the prosthetic valve;
• a plurality of leaflets extending from the three leaflet windows of the leaflet frame;
• and
• a film covering the leaflet frame and the outer frame, a portion of the film extending between the leaflet and outer frame defining a bridge portion coupling the leaflet frame and the outer frame.
