1. A medical electrical lead comprising:
- a first elongate plastic tube including a proximal end, a distal end and an outer surface;
a first conductor extending within the first plastic tube from the proximal end toward the distal end;
a first electrode having an outer diameter, mounted exterior to the outer surface of the first tube and coupled to a distal portion of the first conductor;
a connector terminating the proximal end of the first elongate plastic tube including a connector contact coupled to a proximal portion of the first conductor; and
a second elongate plastic tube formed of a base polymer to which surface modifying end groups are attached, the second tube being mounted exterior to the outer surface of the first tube, extending from a point adjacent to the first electrode proximally toward the connector, and having an outer diameter approximately equal to the outer diameter of the first electrode.

Abstract
A medical electrical lead includes a first elongate plastic tube including an outer surface, a conductor extending within the first plastic tube, an electrode having an outer diameter, mounted exterior to the outer surface of the first tube and coupled to a distal portion of the conductor, and a second elongate plastic tube formed of a base polymer to which surface modifying end groups are attached. The second tube is mounted exterior to the outer surface of the first tube, extends from a point adjacent to the first electrode proximally, and has an outer diameter approximately equal to the outer diameter of the first electrode.
