  • CATHETER SYSTEM FOR SEQUENTIAL DEPLOYMENT OF AN EXPANDABLE IMPLANT
    Publication number: 20240148503
    Abstract: 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.

  • LOCKING ASSEMBLY FOR COUPLING GUIDEWIRE TO DELIVERY SYSTEM
    Publication number: 20220218503
    Abstract: A locking assembly for releasably coupling a first elongate member to a second elongate member is provided. The locking assembly can include a first lumen for anchoring the locking assembly to a catheter and a second lumen for releasably retaining a guidewire to the locking assembly. A release member can interface with the locking assembly and apply a force that decouples the guidewire from the locking assembly.
