Abstract
Embodiments of an implantable prosthetic valve are disclosed. The valve can have an annular frame having a plurality of frame members and a skirt assembly. The skirt assembly can include a laminate having a fabric layer sandwiched between a first covering member and a second covering member. At least one surface of the fabric layer can be exposed at one or more windows in the second covering member. The skirt assembly can be coupled to the annular frame by a suture extending through the fabric layer at the one or more windows and around at least one of the plurality of frame members. Methods for making such an implantable prosthetic valve are also disclosed.

A method for making an implantable prosthetic valve, comprising:
- forming a laminate comprising a fabric layer disposed between first and second covering members, wherein the second covering member includes one or more windows where the fabric layer is exposed;
- placing the laminate against an annular frame;
- and
- suturing the laminate to the annular frame by threading a suture through the fabric layer at the one or more windows of the second covering member and around a portion of the frame.
An implantable prosthetic valve comprising:
- an annular frame having a plurality of frame members;
- and
- a skirt assembly comprising a laminate having a fabric layer sandwiched between a first covering member and a second covering member, wherein the fabric layer is exposed at one or more windows in the second covering member;
- wherein the skirt assembly is coupled to the annular frame by a suture extending through the fabric layer at the one or more windows and around at least one of the plurality of frame members.
