Publication number: 20140005774Abstract: A prosthetic valve assembly for use in replacing a deficient native valve comprises a replacement valve supported on an expandable valve support. If desired, one or more anchor may be used. The valve support, which entirely supports the valve annulus, valve leaflets, and valve commissure points, is configured to be collapsible for transluminal delivery and expandable to contact the anatomical annulus of the native valve when the assembly is properly positioned. The anchor engages the lumen wall when expanded and prevents substantial migration of the valve assembly when positioned in place. The prosthetic valve assembly is compressible about a catheter, and restrained from expanding by an outer sheath. The catheter may be inserted inside a lumen within the body, such as the femoral artery, and delivered to a desired location, such as the heart.Type: ApplicationFiled: January 20, 2011Publication date: January 2, 2014Applicant: Medtronic CoreValve LLCInventors: Jacques SEGUIN, Georg Börtlein

Patent number: 8579966Abstract: A prosthetic valve assembly for use in replacing a deficient native valve comprises a replacement valve supported on an expandable valve support. The valve support, which entirely supports the valve annulus, valve leaflets, and valve commissure points, is configured to be collapsible for transluminal delivery and expandable contact the anatomical annulus of the native valve when the assembly is properly positioned. Portions of the valve support may expand to a preset diameter to maintain coaptivity of the replacement valve and to prevent occlusion of the coronary ostia.Type: GrantFiled: February 4, 2004Date of Patent: November 12, 2013Assignee: Medtronic CoreValve LLCInventors: Jacques Seguin, Georg Börtlein

Publication number: 20120143316Abstract: A prosthetic valve comprises a valve assembly having a base, a plurality of leaflets, and commissures. The valve also comprises a support stent having a plurality of expandable cells and a plurality of longitudinal struts. The support stent is configured to be collapsible for transluminal delivery and expandable to contact the anatomical annulus of the native valve when the prosthetic valve is positioned in situ. The support stent supports the base. The commissures of the valve assembly are secured at the longitudinal struts and adjacent one or more of the expandable cells. The longitudinal struts of the support stent further comprise a plurality of holes, and the plurality of leaflets are secured to the longitudinal struts via threads passing through the plurality of holes.Type: ApplicationFiled: December 7, 2011Publication date: June 7, 2012Applicant: Medtronic CoreValve LLCInventors: Jacques Seguin, Georg Börtlein

Portions of the valve support may expand to a preset diameter to maintain coaptivity of the replacement valve and to prevent occlusion of the coronary ostia. A radial restraint, comprising a wire, thread or cuff, may be used to ensure expansion does not exceed the preset diameter.Type: ApplicationFiled: September 23, 2011Publication date: April 5, 2012Applicant: Medtronic CoreValve LLCInventors: Jacques Sequin, Georg Börtlein

Publication number: 20080140189Abstract: A prosthetic valve assembly for use in replacing a deficient native valve comprises a replacement valve supported on an expandable prosthesis frame. The valve may be delivered transluminally or transmyocardially using a thorascopic or other limited access approach using a delivery catheter. Preferably, the initial partial expansion of the valve is performed against the native valve annulus to provide adequate anchoring and positioning of the valve as the remaining portions of the valve expand. The valve may be delivered using a retrograde or antegrade approach. When delivered using a retrograde approach, a delivery catheter with a pull-back sheath may be used, while antegrade delivery is preferably performed with a delivery catheter with a push-forward sheath that releases the proximal end of the valve first.Type: ApplicationFiled: December 6, 2007Publication date: June 12, 2008Applicant: CoreValve, Inc.Inventors: Than Nguyen, Jacques Seguin, Stan Komatsu, Hung Nguyen, Georg Boertlein
