Patent number: 11931252Abstract: The present invention comprises a novel and safer mechanism of deployment using a self-positioning, self-centering, and self-anchoring method. To embody the present invention, a disk-based valve apparatus allowing the repositioning and retrieval of the implantable valve while working on a dysfunctional valve structure is disclosed. The disk-based valve apparatus may comprise one or more disks, either proximal or distal, a valve-housing component and a valve component. The one or more disks may be either proximal or distal, may be either connected to each other or disconnected from each other and may either be symmetrical or have different shapes and dimensions. The disk-based valve apparatus may be self anchoring, such as anchored by pressure from the one or more disk, or may be anchored using any anchoring.Type: GrantFiled: July 15, 2019Date of Patent: March 19, 2024Assignee: Cephea Valve Technologies, Inc.Inventors: Matteo Montorfano, Alaide Chieffo, Juan F.

Patent number: 11617646Abstract: A prosthetic mitral valve includes an anchor assembly, an annular strut frame, and a plurality of replacement leaflets secured to the annular strut frame. The anchor assembly includes a ventricular anchor, an atrial anchor, and a central portion therebetween. The annular strut frame is disposed radially within the anchor assembly. An atrial end of the annular strut frame is attached to the anchor assembly such that a ventricular end of the annular strut frame is spaced away from the anchor assembly.Type: GrantFiled: January 6, 2020Date of Patent: April 4, 2023Assignee: Cephea Valve Technologies, Inc.Inventors: Dan Wallace, Spencer Noe, Peter Gregg, Juan F.

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: 10285809Abstract: An implant system may include a delivery sheath having an actuator mechanism, an anchoring assistance device including an expandable scaffold including a mid-body section, a cusp interface section, and a crown end arrangement, and a replacement heart valve implant. The cusp interface section includes a plurality of loop portions arranged at radial intervals about the expandable scaffold. Each loop portion is circumferentially spaced apart from another loop portion by a region having a deployment ring, the region being configured to span a commissure of the aortic valve and extending distally a shorter distance from the distal end than the loop portions. An elongate deployment member is configured to releasably engage with the deployment rings to actuate the expandable scaffold from a delivery configuration to a deployed configuration. The replacement heart valve implant is configured to be at least partially disposed within the expandable scaffold in the deployed configuration.Type: GrantFiled: March 3, 2016Date of Patent: May 14, 2019Assignee: BOSTON SCIENTIFIC SCIMED INC.Inventors: Martyn G.
