  • Publication number: 20200405505
    Abstract: A joint replacement in situ gauge system enables a surgeon to measure the appropriate spacing between the two sides of a joint, a convex component and a concave component. A replacement in situ gauge system includes a gauge component to measure the pressure and/or displacement of one joint component with respect to the mating component. A gauge component utilizes a displacement device that displaces the convex or concave component to determine a proper spacing for an implant component. The displacement component may be a bladder that is inflated with a fluid and a gauge may measure the pressure of the bladder through a range of motion. A scale may be used to measure physical displacement. The gauge component may be configured in the convex and/or concave components of the system. The gauge component may be removed and then an implant component may be implanted.

  • Patent number: 6641422
    Abstract: A high intensity discharge lamp (HID) (200) includes an electrically powered lamp (200) having a lamp exterior (220) and at least one lead (226) extending outside of the lamp. An electrical interface (202) includes a male connector (204) fastened at its base (302) to one of the leads (226), an insulate housing (206) having an inner contour (402) shaped to fittedly encompass therein the male connector and at least a portion of the lead, and a cement contact (208) that fastens the housing to the lamp exterior without air gaps. A boot (212) hermetically seals the insulate housing. A female connector (210) is mated to the male connector within the boot, and a feed line (501) having an insulating cover (502) is electrically connected at one end to the female connector and to a power source at the other end.
