Patent number: 8778016Abstract: A method and apparatus for performing mitral valve chordal repair on a patient include attaching at least one filament to a mitral valve leaflet and to a papillary muscle. A first end of a filament can be attached to the mitral valve leaflet and the length of the filament can be adjusted by adjusting the tension of the filament in a catheter. The second end of the filament can be attached to an attachment site.Type: GrantFiled: August 14, 2008Date of Patent: July 15, 2014Assignee: Edwards Lifesciences CorporationInventors: Chris Janovsky, Christopher Olson, Hsingching Crystal Hsu, Carl Swindle, Erin Glines, Ian Shakil, Pooja Sharma, Stanton Rowe

Patent number: 8460366Abstract: Various embodiments of methods and apparatus for treating defective heart valve are disclosed herein. In one exemplary embodiment, a transcatheter heart valve is disclosed that includes an expandable shape memory stent and a valve member supported by the stent. A plurality of micro-anchors can be disposed along an outer surface of the stent for engaging native tissue. The transcatheter heart valve can be configured to be advanced into a dilated valve annulus via a balloon catheter. The balloon can be inflated to expand the transcatheter heart valve from a collapsed diameter to an over-expanded diameter such that the micro-anchors engage tissue along the surrounding valve annulus. After engaging the tissue, the balloon can be deflated and the shape memory stent can retract or recoil toward its predetermined recoil diameter. As the stent recoils, the surrounding tissue is pulled inward by the stent such that the diameter of the valve annulus is reduced.Type: GrantFiled: July 18, 2011Date of Patent: June 11, 2013Assignee: Edwards Lifesciences CorporationInventor: Stanton Rowe

Patent number: 8323335Abstract: Disclosed herein are representative embodiments of methods, apparatus, and systems used to deliver a prosthetic heart valve to a deficient valve. In one embodiment, for instance, a support stent is delivered to a position on the surface of the outflow side of a native heart valve of a patient, the support stent defining a support-stent interior. An expandable prosthetic heart valve is delivered into the native heart valve from the inflow side of the native heart valve and into the support-stent interior. The expandable prosthetic heart valve is expanded while the expandable prosthetic valve is in the support-stent interior and while the support stent is at the position on the surface of the outflow side of the heart valve, thereby causing one or more of the native leaflets of the native heart valve to be frictionally secured between the support stent and the expanded prosthetic heart valve.Type: GrantFiled: February 10, 2009Date of Patent: December 4, 2012Assignee: Edwards Lifesciences CorporationInventors: Stanton Rowe, Francesco Maisano, Oded Meiri

Patent number: 8236049Abstract: A method for replacing a deficient native mitral valve includes positioning a support band around the leaflets of a native mitral valve and expanding a prosthetic heart valve within the native mitral valve. After the prosthetic heart valve is expanded, the leaflets of the native mitral valve are captured between the prosthetic heart valve and the support band. The prosthetic heart valve and support band are delivered into the body as separate and independent components. The prosthetic heart valve and support band may be deliverable into the left ventricle via a transapical approach in a minimally invasive procedure.Type: GrantFiled: June 18, 2010Date of Patent: August 7, 2012Assignee: Edwards Lifesciences CorporationInventors: Stanton Rowe, Francesco Maisano, Oded Meiri

Publication number: 20100030330Abstract: Devices and methods for reshaping a mitral valve annulus are provided. One device according to the invention is configured for deployment in the right atrium and is shaped to apply a force along the atrial septum. The device causes the atrial septum to deform and push the anterior leaflet of the mitral valve in a posterior direction for reducing mitral valve regurgitation. Another embodiment of a device is deployed in the left ventricular outflow tract at a location adjacent the aortic valve. The device may be expandable for urging the anterior leaflet toward the posterior leaflet. Another embodiment of the device includes a first anchor, a second anchor, and a bridge, with the bridge having sufficient length to reach from the coronary sinus to the right atrium and/or superior or inferior vena cava. In a further embodiment a device includes a middle anchor positioned on the bridge between the distal and proximal anchors.Type: ApplicationFiled: August 1, 2008Publication date: February 4, 2010Applicant: Edwards Lifesciences CorporationInventors: Donald E.

Publication number: 20090276040Abstract: A prosthetic mitral valve assembly and method of inserting the same is disclosed. In certain disclosed embodiments, the prosthetic mitral valve assembly has a flared upper end and a tapered portion to fit the contours of the native mitral valve. The prosthetic mitral valve assembly can include a stent or outer support frame with a valve mounted therein, The assembly can be adapted to expand radially outwardly and into contact with the native tissue to create a pressure fit. One embodiment of a method includes positioning the mitral valve assembly below the annulus such that the annulus itself can restrict the assembly from moving in an upward direction towards the left atrium. The mitral valve assembly is also positioned so that the leaflets of the mitral valve hold the assembly to prevent downward movement of the assembly towards the left ventricle.Type: ApplicationFiled: May 1, 2008Publication date: November 5, 2009Applicant: Edwards Lifesciences CorporationInventors: Stanton Rowe, Mark Chau, Son V.

Publication number: 20070168023Abstract: A diagnostic device for determining the amount of change required in a coronary sinus to reduce valve regurgitation. The device includes a distal tube having a distal anchor at a distal end portion of the distal tube, a proximal tube having a proximal anchor at a distal end portion of the proximal tube, and an adjustor to move the distal tube relative to the proximal tube. The proximal tube and the distal tube together form a telescoping elongate body adapted to fit within the coronary sinus, and the device includes a scale to measure the movement of the distal anchor relative to the proximal anchor.Type: ApplicationFiled: March 21, 2007Publication date: July 19, 2007Inventors: Stanton Rowe, Henry Bourang, Sepehr Fariabi, Jan Solem

Publication number: 20060287719Abstract: A two-stage or component-based 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 a non-expandable type, or may be expandable from a compressed state to an expanded state.Type: ApplicationFiled: May 24, 2006Publication date: December 21, 2006Inventors: Stanton Rowe, Larry Wood, Henry Bourang, George Bakis, Benjamin Spenser, Netanel Benichou, Yaron Keidar, Assaf Bash
