Abstract
A connector assembly of an electrophysiologial device. The connector assembly includes a substrate forming a tube extending from a proximal end to a distal end an electrical circuit formed on the substrate, such as etching or printing, where the substrate is optionally non-conductive. In another option, the connector assembly includes clad wires and/or flexible circuits within an insulated terminal structure.
Claims21
A terminal assembly comprising:
- an insulative elongate tube having an outer periphery and a longitudinal axis;
- at least one groove within the outer periphery of the elongate tube;
- a conductor disposed in each groove;
- at least one conductive ring member having an internal surface;
- at least one projection extending from the internal surface of the conductive ring member, the projection disposed within the at least one groove and is electrically coupled with the conductor;
- a terminal pin extending from a pin proximal end to a pin distal end, the terminal pin disposed within the insulative elongate tube;
- and
- insulative material disposed over the insulative elongate tube adjacent to the conductive ring member.
A micro terminal having an outer peripheral surface, the micro terminal comprising:
- a tube of insulation;
- a first conductor embedded within the tube of insulation;
- a second conductor embedded within the tube of insulation;
- a first conductive tab extending from the outer peripheral surface to the first conductor;
- a second conductive tab extending from the outer peripheral surface to the second conductor;
- and
- the tube of insulation having an inner lumen therethrough.
A method comprising:
- forming a terminal assembly including forming a least one groove within an outer periphery of an insulative elongate tube having a longitudinal axis;
- disposing a conductor in each groove;
- placing at least one conductive ring member having an internal surface over the outer periphery of the insulative elongate tube;
- disposing a projection extending from the internal surface of the conductive ring member within the at least one groove;
- disposing a terminal pin within the insulative elongate tube;
- and
- disposing insulative material over the insulative elongate tube adjacent to the conductive ring member.
A method comprising:
- forming a terminal assembly including mechanically and electrically coupling a plurality of conductors with a plurality of rings;
- positioning the rings and conductors around an inner tube;
- molding insulation around the rings, the conductors, and inner tube;
- mechanically and electrically coupling a coil to a terminal pin;
- and
- disposing the coil and the terminal pin through the inner tube.
