Publication number: 20190106717Abstract: The invention is directed to kits, compositions, tools and methods comprising a cyclic industrial process to form biocement. In particular, the invention is directed to materials and methods for decomposing calcium carbonate into calcium oxide and carbon dioxide at an elevated temperature, reacting calcium oxide with ammonium chloride to form calcium chloride, water, and ammonia gas; and reacting ammonia gas and carbon dioxide at high pressure to form urea and water, which are then utilized to form biocement. This cyclic process can be achieved by combining industrial processes with the resulting product as biocement. The process may involve retention of calcium carbonate currently utilized in the manufacture of Portland Cement.Type: ApplicationFiled: October 5, 2018Publication date: April 11, 2019Applicant: Biomason, Inc.Inventors: Ginger K. Dosier, J. Michael Dosier, Kent J. Smith

Patent number: 10231828Abstract: A prosthetic heart valve may include a stent body with a plurality of cells arranged in circumferential rows and a cuff attached to the stent. A leaflet attachment panel may be attached to and span a portion of one of the cells. A prosthetic valve element, such as a leaflet having a belly, may be mounted to the leaflet attachment panel. The leaflet attachment panel may not be integral with the stent body. A reduced overlap area may be defined between a proximal end of the stent body and a proximalmost point of attachment of the leaflet belly to the cuff. The reduced overlap area may have a size dependent upon the circumferential row of cells the leaflet attachment panel is attached to and a position of the portion of the leaflet attachment panel to which the leaflet is mounted. Alternately, the leaflet may be attached directly to the stent.Type: GrantFiled: June 7, 2017Date of Patent: March 19, 2019Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Peter N.
