Abstract
A lead for a stimulation device can include an array of electrodes with each electrode having a front surface and a back surface; a plurality of conductors; a carrier formed around the array of electrodes; and a biocompatible material that may be disposed over and/or joined with the carrier and the back surfaces of the electrodes. A conductor is attached to the back surface of each electrode. The carrier can be formed around the array of electrodes, but does not completely cover the front surface or back surface of the electrodes.
Claims20
A method of making a lead for a stimulation device, the method comprising:
- providing a carrier and an array of electrodes in a pre-determined arrangement, wherein the array of electrodes comprises at least two rows of electrodes with at least one of the rows comprising a plurality of electrodes, wherein the carrier maintains the arrangement of the array of electrodes;
- attaching a plurality of conductors to the array of electrodes maintained by the carrier;
- and
- covering at least one surface of the carrier with a biocompatible material after coupling the plurality of conductors to the array of electrodes to form an insulating covering over connections between the conductors and the array of electrodes.
A method of making a lead for a stimulation device, the method comprising:
- providing an array of electrodes in a pre-determined arrangement, wherein the array of electrodes comprises at least two rows of electrodes with at least one of the rows comprising a plurality of electrodes;
- coupling a plurality of conductors to the array of electrodes;
- and
- molding a biocompatible material around the array of electrodes after coupling the plurality of conductors to the array of electrodes to form an insulating covering over connections between the conductors and the array of electrodes.
A method of making a lead for a stimulation device, the method comprising:
- forming a planar array of electrodes in a pre-determined arrangement by positioning the electrodes in a carrier mold, wherein the array of electrodes comprises at least two rows of electrodes, at least one of the rows comprising a plurality of electrodes;
- molding a carrier around the array of electrodes by inserting a carrier material into the carrier mold such that the carrier material molds around the electrodes;
- coupling a plurality of conductors to the array of electrodes after molding the carrier around the array of electrodes;
- and
- disposing a biocompatible material over at least a portion of the carrier after coupling the plurality of conductors to the plurality of electrodes to form an insulating covering over connections between the conductors and the array of electrodes.
