Textiles, methods of making the same and implantable medical devices using the same

A method of forming an implantable prosthetic valve, wherein the method comprises:

• (a) forming a valve covering material, wherein the step of forming comprises:
• weaving a double cloth comprising a top portion and a bottom portion, wherein the top portion and bottom portion are spaced at a first length;
• wherein the top portion comprises a first woven base layer having a first surface and an opposing second surface and comprising a first plurality of warp yarns and a first plurality of weft yarns;
• wherein the bottom portion comprises a second woven base layer having a first surface and an opposing second surface comprising a second plurality of warp yarns and a second plurality of weft yarns;
• wherein the first and second woven base layers have a first predetermined pattern;
• wherein the top portion and bottom portion are coupled with a plurality of pile yarns such that the second surface of the first woven base layer faces the second surface of the second woven base layer, wherein the plurality of pile yarns extend between the second surface of the first woven base layer and the second surface of the second woven base layer along the first length;
• wherein a first portion of the plurality of pile yarns is interwoven with the first woven base layer and a second portion of the plurality of pile yarns are interwoven with the second woven base layer;
• wherein the first woven base layer is bio-resorbable;
• wherein at least a portion of the second portion of the plurality of pile yarns is integrally fused with at least a portion of the second woven base layer;
• and
• (b) positioning the covering on a prosthetic valve frame to form the valve covering such that the first surface of the first woven base layer is exposed to a natural anatomy.

A prosthetic valve comprising:

• at least one covering comprising:
• a woven base layer having a first surface and a second surface, and a first predetermined pattern;
• a cut pile layer, wherein the cut pile layer has a predetermined thickness and a second predetermined pattern;
• and
• wherein the cut pile layer comprises a plurality of yarns outwardly extending from the second surface of the woven base layer, wherein at least one yarn of the plurality of yarns present in the cut pile layer is a multifilament yarn or a monofilament yarn, and wherein at least a portion of the plurality of pile yarns is integrally fused with the woven base layer;
• and
• wherein the at least one covering is positioned on a valve frame, such that the first surface of the woven base layer is adjacent to the frame.

A prosthetic valve comprising:

• at least one covering comprising:
• a double cloth material comprising a top portion and a bottom portion, wherein the top portion and bottom portion are spaced at a first length;
• wherein the top portion comprises a first woven base layer having a first surface and an opposing second surface and comprising a first plurality of warp yarns and a first plurality of weft yarns;
• wherein the bottom portion comprises a second woven base layer having a first surface and an opposing second surface comprising a second plurality of warp yarns and a second plurality of weft yarns;
• wherein the first and second woven base layers have a first predetermined pattern;
• wherein the top portion and bottom portion are coupled with a plurality of pile yarns such that the second surface of the first woven base layer faces the second surface of the second woven base layer, wherein the plurality of pile yarns extend between the second surface the first woven base layer and the second surface of the second woven base layer along the first length in a second predetermined pattern;
• wherein a first portion of the plurality of pile yarns is interwoven with the first woven base layer and a second portion of the plurality of pile yarns is interwoven with the second woven base layer;
• wherein the first woven base layer is bio-resorbable;
• wherein at least a portion of the second portion of the plurality of pile yarns is integrally fused with at least a portion of the second woven base layer;
• and
• and wherein the at least one covering is positioned on a valve frame such that the second woven base layer is adjacent to the valve frame and the first woven base layer is exposed to a native anatomy.
