  • Amplitude modulated waveform circuitry for electrosurgical devices and systems, and related methods
    Patent number: 11696795
    Abstract: Embodiments relate to circuitry to provide amplitude modulated waveforms in electrosurgical devices. The circuitry can be included in an electrosurgical generator device to provide the amplitude modulated waveforms to an electrosurgical probe coupled with the electrosurgical generator device.
    Type: Grant

  • APPARATUS FOR RETAINING AND SEALING SEPTUM IN INSERTION MECHANISM FOR FLUID DELIVERY DEVICE
    Publication number: 20220409856
    Abstract: An improved wedge is provided for a septum and wedge subassembly in a fluid path of a fluid delivery device such as for use in a catheter insertion mechanism of a patch pump. The wedge has a retaining edge to provide axial force to retain a septum therein to obviate need for additional insertion mechanism components to retain the septum in place as a needle passes therethrough to facilitate insertion of a catheter and then retracts. The retaining edge can be rolled or flanged to extend at least partially over a surface of the septum. The wedge is also configured to provide radial compression on the septum to achieve a sufficient needle and septum interface seal to withstand a filling pressure of the fluid delivery device.
