Mechanical Guides for Controlling Leaflet Folding Behavior During Crimping
Summary
The USPTO published patent application US20260090884A1 for mechanical guides controlling leaflet folding behavior during crimping of transcatheter valve prostheses. The invention by inventors Grant Menon, Yogesh Darekar, and George Hallak includes a leaflet folding accessory with guide fingers configured to hold leaflets in predetermined configurations during compression. The technology applies to transcatheter aortic and other heart valve replacements.
What changed
The USPTO published a patent application for an assembly combining a transcatheter valve prosthesis with a leaflet folding accessory. The accessory uses a plurality of guide fingers that contact the prosthetic valve component and hold leaflets in predetermined configurations during crimping into a delivery configuration and expansion into deployment configuration. CPC classifications indicate applications for transcatheter valves including A61F 2/243, 2/2418, 2/2427, and 2/2466.
Patent applications do not impose compliance obligations on regulated entities. Medical device manufacturers developing transcatheter valve systems may review this publication to assess competitive landscape or freedom-to-operate considerations. No action is required for compliance purposes. This represents routine publication of a patent application; the invention has not yet been granted and no enforceable patent rights exist.

Abstract
An assembly including a transcatheter valve prosthesis and a leaflet folding accessory configured for use when compressing the transcatheter valve prosthesis into the crimped configuration. The transcatheter valve prosthesis includes a stent and a prosthetic valve component including at least one leaflet disposed within and secured to the stent. The transcatheter valve prosthesis has a crimped configuration for delivery within a vasculature and an expanded configuration for deployment within a native heart valve. The leaflet folding accessory includes a plurality of guide fingers. Each guide finger is configured to contact the prosthetic valve component and hold the at least one leaflet in a predetermined configuration when the transcatheter valve prosthesis is compressed into the crimped configuration.
