A medical device comprises a tube (12) having and at least one lumen, a flexible body (102) including a stimulation array (114) to provide an electrical charge for stimulating tissue, an electrical connection to electrically couple the stimulation array to a power source and positioned on the flexible body proximal to the stimulation array, and an electronic component positioned between the stimulation array (114) and the power source. The electronic component includes a memory and a processor configured to implement programmable code stored on the memory. The flexible body (102) is configured to cover at least a portion of the longitudinal length of the tube (12) such that the stimulation array (114) is disposed about an exterior of the tube.
