Lead with braided reinforcement
First Claim
1. An implantable lead, comprising:
- a conductor assembly;
a braided structure that includes a plurality of intertwining strands, wherein the braided structure includes a lumen configured to receive the conductor assembly, the lumen extending in a longitudinal direction;
a first tubing disposed around at least a segment of the braided structure, wherein the first tubing is configured such that an elongation of the first tubing in the longitudinal direction is in a first range, and wherein an elongation of the braided structure in the longitudinal direction is in a second range different from the first range; and
a second tubing located between the first tubing and the braided structure, wherein a gap in a radial direction exists between at least a portion of the first tubing and a portion of the second tubing.

Abstract
A therapy delivery element configured for at least partial insertion in a living body. A braided structure surrounds the conductor assembly. A distal end of the braided structure is attached to an electrode assembly and a free floating proximal end is located near a connector assembly. An outer tubing surrounds the braided structure. The outer tubing includes a proximal end attached to the connector assembly and a distal end attached to the braided structure near the electrode assembly. A proximal tension force applied to the connector assembly acts substantially on the outer tubing and the conductor assembly and a proximal tension force applied to the free floating proximal end acts substantially on the braided structure.

12. A medical system, comprising:
-
a pulse generator configured to generate electrical pulses for stimulating a patient; and an implantable lead configured to be coupled to the pulse generator to deliver the electrical pulses to the patient, wherein the implantable lead includes; a conductor assembly; a braided structure that includes a plurality of intertwining strands, wherein the braided structure includes a lumen configured to receive the conductor assembly, the lumen extending in a longitudinal direction; a first tubing disposed around at least a segment of the braided structure, wherein an elongation of the first tubing in the longitudinal direction is decoupled from an elongation of the braided structure in the longitudinal direction, and wherein the braided structure has a lower percent elongation than the first tubing; and a second tubing located between the first tubing and the braided structure, wherein a gap in a radial direction exists between at least a portion of the first tubing and a portion of the second tubing. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A method, comprising:
delivering electrical stimulation to a patient via an implantable lead that includes; a conductor assembly; a braided structure that includes a plurality of intertwining strands, wherein the braided structure includes a lumen configured to receive the conductor assembly, the lumen extending in a longitudinal direction; a first tubing disposed around at least a segment of the braided structure, wherein a first percentage elongation of the first tubing in the longitudinal direction is different from a second percentage elongation of the braided structure in the longitudinal direction; and a second tubing located between the first tubing and the braided structure, wherein a gap in a radial direction exists between at least a portion of the first tubing and a portion of the second tubing.
