Abstract
An implantable prosthetic valve has an upper frame section and a lower frame section. The upper frame section has a plurality of struts and a first leaflet receiving surface at a lower portion of the upper frame section. The lower frame section has a second leaflet receiving surface at an upper portion of the lower frame section. An edge of a flexible leaflet is disposed between the first and second leaflet receiving surfaces to attach the leaflet to the upper and lower frame sections.
Claims14
An implantable prosthetic device comprising:
- an upper frame section having a plurality of struts and a first leaflet receiving surface at a lower portion of the upper frame section;
- a lower frame section having a second leaflet receiving surface at an upper portion of the lower frame section;
- and
- at least one flexible leaflet with a first edge portion, the first edge portion being disposed between the first and second leaflet receiving surfaces.
An implantable prosthetic device comprising:
- a frame comprising a plurality of frame sections, each frame section having a lower portion with a scalloped shape;
- and
- a flexible membrane comprising a plurality of flexible leaflets, each flexible leaflet having a lower portion with a scalloped shape;
- wherein the lower portion of each flexible leaflet is attached to the lower portion of each frame section.
A method of assembling an implantable prosthetic valve comprising a flexible membrane and crimpable frame with an upper and lower part, the method comprising:
- partially crimping the frame to have a diameter that is less than the diameter of the frame when the valve is expanded to its functional size;
- positioning an edge of the flexible membrane between the upper and lower part of the frame;
- and
- securing the edge of the flexible membrane to both the upper and lower part of the frame.
