  • Patent number: 11865020
    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.

  • Patent number: 11864919
    Abstract: A flexible, passive pressure sensor includes three LC tank circuits. The first LC tank circuit is a pressure sensing LC tank circuit, having a capacitance that varies in response to changes in environmental pressure. The second and third LC tank circuits are reference LC tank circuits, having capacitances that are relatively constant over changes in environmental pressure. A measurement tool measures the resonant frequencies of the three LC tank circuits and then computes a pressure measurement that accounts for changes in resonant frequencies in the LC tank circuits due to environmental effects and deforming.
