LEAD COMPRISING A DRUG REGION SHARED BY MORE THAN ONE ELECTRODE
First Claim
1. A lead comprising:
- a lead body extending from a lead proximal end portion to a lead distal end portion, and having a lead intermediate portion therebetween;
an electrical connector assembly coupled to the lead proximal end portion;
at least a first and a second electrode disposed along the lead body, the electrodes electrically coupled to the connector assembly by way of one or more longitudinally extending conductors; and
a drug region disposed between the first and the second electrodes, the drug region configured to be shared by the electrodes.

Abstract
One or more multi-electrode lead couplable with a medical device, such as an implantable medical device. Each lead includes a lead body extending from a lead proximal end portion to a lead distal end portion. The proximal end portion includes a connector assembly for connection to the medical device. An intermediate or distal end portion includes two or more electrodes and a drug region shared by at least two of the electrodes. In one example, the drug region is positioned between two or more electrodes such each of the electrodes may benefit from a drug in the region. In another example, the medical device comprises circuitry adapted to sense a heart in a first instance and stimulate the heart in a second instance using a selected electrode configuration. A method of forming a lead having a drug region shared by more than one electrode is also discussed.

14. An implantable lead for use with an implantable medical device, the implantable lead comprising:
-
a lead body extending from a proximal end to a distal end and having at least one elongated electrical conductor contained therewithin and extending between the proximal end and the distal end; two or more electrodes disposed on the lead body and electrically coupled with the at least one conductor; and a drug region positioned directly adjacent the two or more electrodes, the drug region configured to dispense a drug to the electrodes. - View Dependent Claims (15, 16, 17, 18, 19)

20. A method comprising:
-
forming a lead body encasing a substantial portion of one or more electrical conductors, including forming a lead body extending from a proximal end portion to a distal end portion and having an intermediate portion therebetween; disposing a first electrode on the lead body near the lead intermediate or distal end portion; disposing a second electrode on the lead body a selected distance away from the first electrode; and disposing a drug region on the lead body in a position such that the drug is shared by the first and second electrodes. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)
