Lead extension system for use with a microstimulator
First Claim
1. A stimulation system comprising a leadless microstimulator having two stimulating electrodes attached to at least one extension lead;
- a monopolar adapter, having an inner, adapter chamber that is sized to accept placement of the microstimulator therein,wherein the adapter chamber has an adapter opening on one end of the adapter; and
wherein the monopolar adapter has an indifferent electrode; and
a connector having a contact connected to the at least one extension lead, which, in turn, is connected to the stimulating electrode,wherein at least part of the connector is dimensioned to be inserted into the opening of the monopolar adapter; and
wherein the connector contact is in contact with one of the stimulating electrodes of the microstimulator.

Abstract
An adapter system is provided for adapting and connecting a leadless microstimulator to a separate monopolar, bipolar, or tripolar electrode. Advantageously, the microstimulator does not need to be physically modified. The adapter system encloses the microstimulator and electrically connects the microstimulator to the selected, separate electrode via an extension lead or leads. The adapter has two forms: a monopolar adapter having a single opening or a bipolar adapter having two openings. The separate electrode is equipped with at least one extension lead having a connector that can be inserted into the opening of the monopolar adapter or the bipolar adapter and connect to the microstimulator that is placed within the monopolar or bipolar adapter.
