Abstract:
An electrode system adapted for use with a tissue stimulation device comprising:an electrode array comprising an elongate flexible carrier, a plurality of spaced-apart electrode contacts exposed along at least one surface of the flexible carrier, and wires embedded within the flexible carrier and connected to the electrode contacts;a flexible positioner adapted for insertion into a body cavity, said flexible positioner having front and rear sides, said body cavity having front and back walls, said flexible positioner being adapted for insertion into the body cavity so that the positioner assumes a position within the body cavity having its rear side lie against the back wall of the cavity, and leaving an open channel between the front side of the positioner and the front wall of the body cavity;wherein the electrode array and the flexible positioner may both occupy the body cavity at the same time, with the electrode array being located within the open channel created between the front side of the positioner and the front wall of the body cavity so that the electrode contacts of the electrode array are positioned adjacent the front wall of the body cavity; anddrug delivery means for delivering a drug into the body cavity while the body cavity is occupied by the flexible electrode array and the flexible positioner.
