Circuitry for medical stimulation systems

A medical device comprising:

• a flexible body;
• an electrode positioned on the flexible body, wherein the electrode is configured to provide an electrical charge for stimulating tissue;
• an electrical connection including a proximal end and a distal end, wherein the electrical connection is configured to electrically couple the electrode to a power source;
• an electrical lead connecting the electrode to the electrical connection, wherein the electrical lead is on or in the flexible body;
• an electronic component between the proximal end of the electrical connection and the electrode, wherein the electronic component includes a memory, a sensing circuit, a radio-frequency identification tag, a processor, or a combination thereof;
• and
• a dielectric substrate film disposed between the electrode and the electrical lead, wherein the dielectric substrate film includes a hole filled with a conductive material electrically connecting the electrode to the electrical lead.

A medical device comprising:

• a tube including a lumen;
• and
• a circuit having a flexible body, wherein the circuit comprises:
• a distal portion, wherein the distal portion includes an electrode configured to provide an electrical charge for stimulating tissue;
• a proximal portion coupled to a distal end of an electrical connection, wherein the proximal portion is angled relative to the distal portion, and the electrical connection is configured to electrically couple the electrode to a power source;
• an electronic component between a proximal end of the electrical connection and the distal portion of the circuit, wherein the electronic component includes a memory, a sensing circuit, a radio-frequency identification tag, a processor, or a combination thereof;
• a conductive lead electrically coupled to the electrical connection and the electrode;
• and
• a via between the conductive lead and the electrode, wherein the via provides an electrical connection between the conductive lead and the electrode.
