  • Stent having adjacent elements connected by flexible webs
    Patent number: 11103372
    Abstract: A stent incorporating flexible, preferably polymeric, connecting elements into the stent wherein these elements connect adjacent, spaced-apart stent elements. Preferably the spaced-apart adjacent stent elements are the result of forming the stent from a helically wound serpentine wire having space provided between adjacent windings. Other stent forms such as multiple, individual spaced-apart ring-shaped or interconnected stent elements may also be used. The connecting elements are typically web-shaped and result from creating slits or apertures in a covering of graft material applied to the stent and then, for example, applying heat to cause the slits or apertures to enlarge. The remaining graft material forms the interconnecting webs between the adjacent stent elements.

  • Deployment system for an endoluminal device
    Patent number: 11103373
    Abstract: The present invention is directed to a deployment system for an endoluminal device. The deployment system includes a confining sheath placed around a compacted endoluminal device. A deployment line is provided in the system. As the deployment line is actuated, the sheath retracts from around the compacted endoluminal device. Once the sheath is retracted from around the compacted endoluminal device, the endoluminal device is operable to expand. Any remaining sheath material is removed from the implantation site along with the deployment line.

  • Frame with integral sewing cuff for prosthetic valves
    Patent number: 11065112
    Abstract: Described embodiments are related to a prosthetic valve for surgical placement with a sewing cuff durably attached to a frame.
