Abstract
An internal defibrillation electrode (10) is disclosed including a disposable electrode (12) and a reusable handle (14). The electrode includes an electrode spoon (16), a shaft (18), and a barrier sleeve (20). The handle includes a handle body (58), electrical cable (60), sleeve connector (62), and electrical connector (64). The handle has a dagger-style configuration that makes the electrode assembly easy to use and is further constructed to allow the electrode to be quickly and reliably attached. In that regard, during assembly, a bayonet (32) on the shaft of the electrode is engaged in a bayonet receptacle (68) of the handle. The sleeve is then pulled over the handle to form a barrier between the handle and the environment. After the electrode assembly is used, the sleeve is removed from the handle, the electrode disengaged from the handle, and the electrode disposed of. After attaching a new electrode, the handle is then ready for immediate service. The handle can also be used with a reusable electrode that does not include a barrier sleeve. To that end, the handle is constructed to exhibit a relatively long life when subjected to repeated steam sterilization.
