  • Patent number: 12268603
    Abstract: A delivery catheter for a stent. The delivery catheter may comprise a distal end and a proximal end. The distal end includes a stent attachment region adapted to receive a stent. The stent may be of the self-expanding type. The catheter further comprises a handle at its proximal end and at least one sheath which may at least partially circumferentially cover said stent such as to retain it in a collapsed configuration. The sheath is coupled at its proximal end to an actuator located on said handle portion.

  • Patent number: 12115070
    Abstract: Embodiments include implantable valves with attached polymeric components. In an embodiment, an implantable valve is included having a frame comprising a plurality of frame struts. The frame defines a central lumen and at least one of the frame struts defines a connection aperture. The implantable valve can include at least one valve leaflet including a coaptation edge and two connection portions, with one connection portion disposed on either end of the coaptation edge. The connection portion can be disposed within the connection aperture thereby coupling the valve leaflet to the frame. Other embodiments are also included herein.
