Latest Patents

**Two Stage Tricuspid Valve Implant.** This invention describes a prosthetic tricuspid valve system with a collapsible anchor frame and a collapsible prosthetic valve. The anchor’s support structure has a waisted central portion and flared atrial and ventricular portions designed to clamp around a native valve annulus. Sheets attached to the flared portions include central apertures, while a fabric valve-receiving member connects them to form a conduit. The prosthetic valve, which includes a stent and leaflets, can expand within the anchor’s receiving member.

**Transcatheter Prosthetic Atrioventricular Valve.** This invention describes a collapsible and expandable valve with an outer stent, an inner stent, and prosthetic leaflets mounted within the inner stent. The outer stent includes atrial and ventricular discs connected by posts, while connectors couple the inner and outer stents. The design leaves portions of the outer stent without metal between adjacent posts, with the metal-free spaces extending across a portion of the stent’s circumference.

Career Highlights

Licht’s disclosed inventions address structural designs for prosthetic heart valves intended for transcatheter use. His work includes mechanisms for anchoring a valve at the native annulus and configurations that connect inner and outer stent structures.
