Publication number: 20230034126Abstract: A method of delivering a prosthetic mitral valve includes delivering a distal anchor from a delivery sheath such that the distal anchor self-expands inside a first heart chamber on a first side of the mitral valve annulus, pulling proximally on the distal anchor such that the distal anchor self-aligns within the mitral valve annulus and the distal anchor rests against tissue of the ventricular heart chamber, and delivering a proximal anchor from the delivery sheath to a second heart chamber on a second side of the mitral valve annulus such that the proximal anchor self-expands and moves towards the distal anchor to rest against tissue of the second heart chamber. The self-expansion of the proximal anchor captures tissue of the mitral valve annulus therebetween.Type: ApplicationFiled: October 7, 2022Publication date: February 2, 2023Applicant: Cephea Valve Technologies, Inc.Inventors: Juan F. Granada, Gary Erzberger, Michael P. Corcoran, Dan Wallace, Matteo Montorfano, Alaide Chieffo

Patent number: 8366741Abstract: The present invention is an occlusion device having a centering arm network that self-centers across a defect and can be retrieved and redeployed in situ. A self centering system allows the center of the occlusion device to remain properly positioned within the defect, which increases the effectiveness of the occlusion device. The self centering system is comprised of a plurality of centering arms which define a flexible intermediate zone. In addition, the occlusion device of the present invention has a plurality of right arms connected to the plurality of centering arms which make it possible to retrieve and redeploy the occlusion device in situ.Type: GrantFiled: September 13, 2007Date of Patent: February 5, 2013Assignee: Cardia, Inc.Inventors: Dara Chin, Michael P. Corcoran, Joseph A. Marino
