Patent number: 9339381Abstract: A prosthetic mitral heart valve having four separate flexible leaflets. The heart valve includes a support frame that may be non-circular, for example elliptical or “D-shaped”. The support frame may have an undulating outflow edge defined by four inflow cusps and four outflow commissures to which each of the flexible leaflets attaches. The support frame may comprise an undulating wireform and a surrounding stent defining a structure having four cantilevered posts projecting in the outflow direction to support the four leaflets. The heart valve is designed to be secured in the annulus and function as a standalone unit without papillary muscle connections to the leaflets. The four leaflets may be arranged in two opposed pairs, one pair being smaller than the other pair. The larger pair of leaflets may be identical, or differently sized. Existing sizes of heart valve leaflets may be utilized with the smaller leaflets being at least two leaflet sizes smaller than the larger leaflets in odd millimeter increments.Type: GrantFiled: October 31, 2008Date of Patent: May 17, 2016Assignee: Edwards Lifesciences CorporationInventor: Derrick Johnson

Patent number: 9113999Abstract: A positioning anchor is provided for a stent-graft for implantation to treat a damaged body lumen. The positioning anchor is generally tubular surrounding a primary fluid conduit. Arms extend laterally from the generally tubular structure of the anchor surrounding lateral fluid conduits. The form of these arms is preferably custom configured to match a particular patient's luminal geometry. The anchor thus fits within the luminal geometry to remain in a desired fixed position for implantation of the anchor and any stent-graft coupled to the anchor. The anchor is most preferably formed with two walls having a void therebetween which can be filled with fixation media to further secure the anchor at the desired implantation site. A lumen shaper balloon and delivery catheter are also disclosed for proper delivery, expansion and inflation of the positioning anchor and stent-graft elements according to this invention.Type: GrantFiled: October 22, 2007Date of Patent: August 25, 2015Assignee: Nellix, Inc.Inventors: Charles S.
