DEVICE: TULA (00840128600023)

A small, hollow cylinder intended to be implanted, by insertion through the tympanic membrane, for ventilation or drainage of the middle ear. Otherwise known as a myringotomy tube, grommet or an aural vent tube, it is made of materials such as polytetrafluoroethylene (PTFE), polyethylene (PE), silicon elastomer, or porous polyethylene. One type, known as the malleus clip tube, attaches to the malleus. Disposable devices associated with implantation may be included with the device, which may be used to implant bilateral tubes.

An assembly of portable devices that may be used as an alternative to injections to transport ionic-solution medication through the movement of ions resulting from an applied electric field, to locally administer the medication transcutaneously. It typically consists of a disposable, battery-powered, current generator that supplies a constant direct current [e.g., 0.5 to 4 milliampere (mA)], a delivery electrode which typically contains a small reservoir of buffering agent and the medication (e.g., a corticosteroid or anaesthetic), a return electrode, and connecting lead wires. This is a single-use device.
