Abstract
Medical system lead adapters distribute stimulation signals from a port of a medical device to both a primary medical lead and a secondary medical lead. The lead adapters provide for the selectable bridging of secondary lead contacts to thereby provide for customized stimulation patterns. The lead adapters may include a primary lead connector, a secondary lead connector, and a pin connector. A pin is selected to provide a particular stimulation pattern for the secondary lead and is inserted into the pin connector to thereby bridge together contacts of the pin connector that are also connected to contacts of the secondary lead connector.
