Publication number: 20220133474Abstract: A transcatheter prosthetic heart valve includes a stent frame and a leaflet material. The stent frame includes a top portion and a bottom portion. The leaflet material includes a lower portion attached to the stent frame and an upper portion that includes leaflets capable of moving between an open configuration and a closed configuration. At least a portion of the leaflet material weaves through the stent frame. The transcatheter prosthetic heart valve also includes one or more reinforcement components coupled to the stent frame and/or to the leaflet material to enhance performance of the transcatheter heart valve.Type: ApplicationFiled: January 14, 2022Publication date: May 5, 2022Applicants: Ohio State Innovation Foundation, Georgia Institute of Technology, Colorado State University Research FoundationInventors: Hieu Bui, Lakshmi Prasad Dasi, Megan Heitkemper, Susan James, Nipa Khair

Patent number: 11255786Abstract: The stiffness and topology of ultra-small circular DNAs and DNA/peptide hybrids are exploited to create a transducer of enzyme activity with low error rates. The modularity and flexibility of the concept are illustrated by demonstrating various transducers that respond to either specific restriction endonucleases or to specific proteases. In all cases the output is a DNA oligo signal that, as we show, can readily be converted directly to an optical readout, or can serve as input for further processing, for example, using DNA logic or amplification. By exploiting the DNA hairpin (or stem-loop) structure and the phenomenon of strand displacement, an enzyme signal is converted into a DNA signal, in the manner of a transducer. This is valuable because a DNA signal can be readily amplified, combined, and processed as information.Type: GrantFiled: June 16, 2021Date of Patent: February 22, 2022Assignee: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Mario Ancona, Hieu Bui
