  • Patent number: 11896440
    Abstract: A medical delivery system including a carrier and a lead delivery device. The carrier defines a carrier body configured to engage a stereotactic system (or a similar pointing device with or without navigation/robotic assistance). The carrier defines a carrier channel configured to engage the lead delivery device and impart a torque to a portion of the lead delivery device. The lead delivery device and carrier are configured to cause the imparted torque to cause a cannula of the lead delivery device to rotate about a longitudinal axis of the lead delivery device. The cannula is configured to cause a rotation of an implantable lead within the cannula when the cannula is caused to rotate. The cannula is configured to translate substantially parallel to the longitudinal axis relative to the implantable lead.

  • Patent number: 4245749
    Abstract: A safety device for a pressure vessel having an opening therein in which is positioned an upstanding base secured around the vessel opening with a frangible diaphragm covering the opening. A protective cap covers the base with the frangible diaphragm and has a central aperture therein covered by a transparent material providing continuous visibility of the frangible diaphragm. The protective cap has an internal annular seat to retain the frangible diaphragm in place and spaced apart fasteners maintain the cap fixedly connected to the base.
