Benefits of technology

The patent describes a way to coat fabrics with a polymer layer to create a coated fabric. The coating can provide improved properties to the fabric, such as adjusting porosity, surface roughness, strength, flexibility, lubricity, and promoting folding in specific regions. The coating can also be a partial coating or a contoured coating to add specific structural features or provide different patterns. The coated fabrics can be used in a variety of applications such as heart valve assemblies.

Problems solved by technology

Those generalized disclosures show that, while the concept of polymer-based implantable medical devices, and in particular valves, is known, actually successfully taking the broad concept to working solutions is far more challenging.

Embodiment Construction

[0111]As used herein in connection with a prosthetic heart valve, the term “inflow end” refers to the end of the heart valve through which blood enters when the valve is functioning as intended, and the term “outflow end” refers to the end of the heart valve through which blood exits when the valve is functioning as intended. As used herein, the terms “proximal” and “upstream” refer to the inflow end of a prosthetic heart valve and these terms may be used interchangeably. The terms “distal” and “downstream” refer to the outflow end of a prosthetic heart valve and also may be used interchangeably. As used herein, the terms “generally,”“substantially,” and “about” are intended to mean that slight deviations from absolute are included within the scope of the term so modified. When used herein in the context of a prosthetic heart valve, or a component thereof, the lengthwise or axial direction refers to a direction parallel to a longitudinal axis passing through the center of the stent ...

Abstract

At least a portion of fabrics for use in medical devices is formed from polymeric materials. The fabrics may be uncoated, partially coated or fully coated with one or more layers of a polymer. The fabrics may be used for the leaflets and / or cuffs of prosthetic heart valves and as a component of other medical devices.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application is a continuation-in-part of U.S. patent application Ser. No. 16 / 713,356, filed Dec. 13, 2019, which claims the benefit of the filing dates of United States Provisional Patent Application Nos. 62 / 779,176, filed Dec. 13, 2018; 62 / 925,379, filed Oct. 24, 2019; 62 / 925,391, filed Oct. 24, 2019; 62 / 925,402, filed Oct. 24, 2019; and 62 / 925,412, filed Oct. 24, 2019, the disclosures of all of which are hereby incorporated by reference herein.BACKGROUND OF THE DISCLOSURE[0002]The present disclosure relates to synthetic fabric materials that can be used in various medical devices and the medical devices including the synthetic fabric materials. For purposes of discussing the state of the art, however, prosthetic heart valves, and particularly collapsible / expandable prosthetic heart valves useful for delivery through a catheter or trocar, will be exemplified.[0003]Prosthetic heart valves, including surgical heart valves and c...
