Publication number: 20150112430Abstract: A heart valve therapy system including a delivery device and a stented valve. The delivery device includes an outer sheath, an inner shaft, an optional hub assembly, and a plurality of tethers. In a delivery state, a stent frame of the prosthesis is crimped over the inner shaft and maintained in a compressed condition by the outer sheath. The tethers are connected to the stent frame. In a partial deployment state, the outer sheath is at least partially withdrawn, allowing the stent frame to self-expand. Tension in the tethers prevents the stent frame from rapidly expanding and optionally allowing recapture. Upon completion of the stent frame expansion, the tethers are withdrawn.Type: ApplicationFiled: October 21, 2014Publication date: April 23, 2015Inventors: Marian Creaven, Marc Anderson, Kate Corish, Declan Costello, Niall Duffy, Joshua Dwork, John Gallagher, Patrick Griffin, Gavin Kenny, Deirdre McGowan Smyth, John Milroy, Jason Quill, Herinaina Rabarimanantsoa Jamous, Paul Rothstein, Jeffrey Sandstrom, Edmond Sheahan, Frank White

Patent number: 8986371Abstract: A method for treating paravalvular leakage at a location of a stented prosthetic valve includes the steps of delivering a clip to a location adjacent chordae tendinae of a native valve, and deploying the clip such that the clip captures at least some of the chordae tendinae of the native valve, thereby increasing tension in the captured chordae tendinae. The clip is delivered to the location in a collapsed stated and is released from a sheath convert to an undeflected or relaxed state. After the clip is released from the sheath, the clip is rotated to capture the chordae tendinae. The clip is then released from the delivery system and the delivery system is retracted.Type: GrantFiled: January 8, 2013Date of Patent: March 24, 2015Assignee: Medtronic CV Luxembourg S.a.r.l.Inventors: Jason Quill, Paul Rothstein

Publication number: 20150018940Abstract: Systems and methods for modifying a heart valve annulus in a minimally invasive surgical procedure. A helical anchor is provided, having a memory set to a coiled shape or state. The helical anchor is further configured to self-revert from a substantially straight state to the coiled state. The helical anchor is loaded within a needle that constrains the helical anchor to the substantially straight state. The needle is delivered to the valve annulus and inserted into tissue of the annulus. The helical anchor is then deployed from the needle (e.g., the needle is retracted from over the helical anchor). Once deployed, the helical anchor self-transitions toward the coiled shape, cinching engaged tissue of the valve annulus.Type: ApplicationFiled: July 10, 2014Publication date: January 15, 2015Inventors: Jason Quill, Cynthia Clague, Michael Green, Alexander J.
