Publication number: 20150105856Abstract: A heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The prosthetic valve comprises a support structure that is deployed at a treatment site. The prosthetic valve further comprises a valve member configured to be quickly connected to the support structure. The support structure may take the form of a stent that is expanded at the site of a native valve. If desired, the native leaflets may remain and the stent may be used to hold the native valve open. In this case, the stent may be balloon expandable and configured to resist the powerful recoil force of the native leaflets. The support structure is provided with a coupling means for attachment to the valve member, thereby fixing the position of the valve member in the body. The valve member may be expandable or a non-expandable type.Type: ApplicationFiled: December 15, 2014Publication date: April 16, 2015Inventors: Stanton J. Rowe, Larry L. Wood, Henry Bourang, George Bakis, Benjamin Spenser, Netanel Benichou, Assaf Bash, Yaron Keidar

Publication number: 20140343670Abstract: Certain embodiments of the present disclosure provide a prosthetic valve (e.g., prosthetic heart valve) and a valve delivery apparatus for delivery of the prosthetic valve to a native valve site via the human vasculature. The delivery apparatus is particularly suited for advancing a prosthetic heart valve through the aorta (i.e., in a retrograde approach) for replacing a diseased native aortic valve. The delivery apparatus in particular embodiments is configured to deploy a prosthetic valve from a delivery sheath in a precise and controlled manner at the target location within the body.Type: ApplicationFiled: May 20, 2014Publication date: November 20, 2014Applicant: Edwards Lifesciences CorporationInventors: George Bakis, Thanh V.

Publication number: 20080221673Abstract: An improved medical implant for treating mitral regurgitation is provided. The medical implant comprises proximal and distal anchors connected by a bridge. The medical implant is configured to be delivered into a coronary sinus using a minimially invasive procedure. The bridge is preferably made of a shape memory material which is biased to contract after the implant is delivered. The medical implant further comprises a reinforcement mechanism configured to limit stresses and strains along the length of the bridge. In a preferred embodiment, the reinforcement mechanism is fixed to a plurality of attachment points along the bridge, thereby preventing excessive elongation between any two attachment points. A resorbable material is preferably disposed within gaps along the length of the bridge to temporarily maintain the bridge in an elongated condition.Type: ApplicationFiled: February 15, 2008Publication date: September 11, 2008Inventors: Donald Bobo, George Bakis, Minh T. Ma, Philip P. Corso

Patent number: 5851461Abstract: Disclosed is a method of producing polysaccharide foams and foams produced by the method. The polysaccharide foams are formed from a wet condition and are convection dried with a flow of warm or hot air. Such foams exhibit improvements over foams dried under ambient conditions. The present invention also discloses the formation of multi-ply foam layers. At least two sheets of foam layers are layered together and laminated either mechanically or chemically to produce a composite structure.Type: GrantFiled: February 14, 1997Date of Patent: December 22, 1998Assignee: Albany International Research Co.Inventors: George Bakis, Dana Burton Eagles, John F.

Patent number: 5456836Abstract: A self-supporting filter element is produced from a precursor fiber web according to one of several methods. The precursor fiber web contains heat-shrinkable fibers or binder fibers or both. The web is exposed to temperatures sufficiently elevated to cause shrinkage of the fibers or melting of the binder. After cooling the web, the filter elements produced are self-supporting, and may have densities up to 500 kg/m.sup.3 to improve filtration while retaining good functional characteristics for operating pressure drop and air permeability. The self-supporting filter elements can be constructed of one material, and thus may be suitable for recycling.Type: GrantFiled: February 28, 1994Date of Patent: October 10, 1995Assignee: Albany International Corp.Inventors: Andrew B. Jeffery, George Bakis, John Skelton
