IMPLANTABLE MEDICAL LEADS WITH FLEXIBILITY AND EXTENSIBILITY, AND HAVING A SUBSTANTIALLY TWO-DIMENSIONAL NATURE
First Claim
1. An implantable medical lead comprising:
- a substantially two-dimensional, generally planar bundle over at least a portion of a length of the medical lead, the bundle comprising a first lead body and a second lead body arranged side-by-side and defining the plane of the bundle;
a plurality of conductive elements disposed within at least one of the first and second lead bodies, each conductive element extending between first and second conductive lead terminations for electrical connection between an electrode and a control device;
wherein at least the portion of the bundle of the medical lead is extensible to increase flexibility of the medical lead by way of a non-linearly shaped length comprising a pattern that is two-dimensional substantially in the same plane as the bundle, the two-dimensional pattern including pattern portions that are elastically deformable in shape to permit the extensibility of at least a portion of the medical lead.

Abstract
Implantable medical leads that are flexible and extensible in a controllable manner with a substantially two-dimensional profile to fit between adjacent tissue layers and to facilitate subject body movements. In particular, implantable medical leads able to permit and withstand multiple degree of freedom of movement that are useful for use in the neck region of a subject body and other regions of any subject'"'"'s body that may benefit from increased flexibility and extensibility. Features of medical leads are utilized to permit extensibility and are based upon the provision of shaped features that controllably permit lead extension under low load, but that maintain a desired shape under no load. The shaped lead portions provide extensibility to the lead as the shapes elastically deform under load.
