Abstract
An insulative body of a medical electrical lead electrode assembly includes a pre-formed channel having a section extending at an angle to a longitudinal axis of the body. An electrode portion of a conductive component has an electrode contact surface facing outward from a first side of the body and a coupling portion embedded in the body. A conductor, which is coupled to the coupling portion of the component, is disposed in the channel.
Claims16
An implantable medical system, comprising:
- a stimulation device;
- and
- an electrical paddle lead that comprises:
- an insulative carrier including a first side and a second side opposite the first side;
- a plurality of conductive components, each of the conductive components including at least one tab and an electrode portion having an inward facing surface and an outward facing contact surface, the electrode portion of each conductive component being disposed on the first side of the carrier, each tab of each conductive component extending away from the corresponding electrode portion through the carrier and bending to extend along the second side of the carrier to secure the conductive component to the carrier, the electrode portions arranged in at least one column, the carrier extending beneath at least a portion of the electrode portion of each conductive component;
- at least one elongate insulative tubular body having an end with a plurality of contacts that are electrically connected to the stimulation device;
- a plurality of conductors extending within the at least one elongate insulative tubular body, each of the plurality of conductors being electrically coupled to a corresponding one of the plurality of contacts and to a corresponding one of the conductive components, the conductive components being powered by the plurality of contacts being electrically connected to the stimulation device;
- and
- an insulative layer molded over the tabs and the second side of the carrier to form a first side of a paddle-shaped body of the implantable medical electrical paddle lead.
