Refillable reservoir lead systems
First Claim
1. A medical electrical lead system configured to be at least partially implanted in a body of a subject, comprising:
- a lead body comprising a proximal end and a distal end and a first lumen extending at least partially therebetween;
at least one electrode in the proximity of the distal end of the lead body; and
a reservoir in fluid communication with the first lumen and in the form of a second lumen of the lead body or a protrusion extending from the first lumen of the lead body, wherein the protrusion is configured to be refilled whether the protrusion is implanted in the body of the subject or external to the body of the subject during use,wherein the reservoir is located at a position removed from the distal end of the lead body.

Abstract
Medical electrical lead systems and related methods are described. The medical electrical lead systems may be configured to be at least partially implanted in a body of a subject. Some variations of the medical electrical lead systems may comprise a lead body comprising a proximal end and a distal end and a lumen extending at least partially therebetween, at least one electrode in the proximity of the distal end of the lead body, and a reservoir in fluid communication with the lumen, where the reservoir is located at a position removed from the distal end of the lead body. Certain variations of the medical electrical lead systems may comprise a lead body comprising a proximal end and a distal end and first and second lumens extending at least partially therebetween, and at least one electrode in the proximity of the distal end of the lead body.
