Publication number: 20240148503Abstract: 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: ApplicationFiled: November 8, 2023Publication date: May 9, 2024Applicant: JenaValve Technology, Inc.Inventors: Kevin CHU, Rolando LEE, Kendall SMITH
