Patent number: 12171658Abstract: Systems and methods for sequential deployment of a prosthetic valve using a delivery catheter are described. The delivery catheter may include a deployment assembly including an end cone, a distal sleeve, a prosthetic support, an anchor sleeve and an anchor support. The delivery catheter may further include a handle having a manipulator including a guide that is connect to the deployment assembly with a force transmission tube. The guide may have various channels for interfacing with a protrusion of the handle and may be guided by the protrusion to sequentially deploy the prosthetic valve from the deployment assembly. For example, the guide may cause the distal sleeve to release a distal end of the prosthetic valve and subsequently cause an anchor support to release a proximal end of the prosthetic valve.Type: GrantFiled: November 8, 2023Date of Patent: December 24, 2024Assignee: JenaValve Technology, Inc.Inventors: Kevin Chu, Rolando Lee, Kendall Smith

Patent number: 11337800Abstract: The disclosure relates to heart valve prostheses with the reduced need of pacemaker implantation and improved means for positioning the replacement heart valve. In one aspect of the present disclosure, the stent scaffold of the valve prosthesis includes axially extending locators. The locators may be positioned within the cusp of the native aortic valve. Placement of the locators within the cusps may prevent further proximal movement of the stent scaffold into the left ventricle. By adjusting the location of the proximal end of the locators with respect to the proximal end of the stent scaffold, infra-annular placement of the stent scaffold in the aortic annulus may be assured. In another aspect, means for visualizing the positioning of replacement heart valves at an implant site inside an individual's body is disclosed.Type: GrantFiled: July 10, 2020Date of Patent: May 24, 2022Assignee: JenaValve Technology, Inc.Inventors: Stefan Schreck, Hussain S.
