Implantable lead with braided conductors

An apparatus comprising:

• an elongated body;
• a stylet coil including a stylet coil lumen, the stylet coil extending within the elongated body;
• and
• a conductor assembly including a plurality of insulated electrical conductors braided in a tubular braided configuration around the stylet coil, the tubular braided configuration including the plurality of insulated electrical conductors braided with one another, the conductor assembly including an inner lumen with a diameter greater than an outside diameter of the stylet coil, wherein the inner lumen of the conductor assembly is separated from the stylet coil by a gap with the elongated body in a relaxed condition, wherein axial elongation of the elongated body reduces an inner diameter of the conductor assembly to close the gap and cause the conductor assembly to constrict around the stylet coil.

An apparatus comprising:

• an elongated body;
• a stylet coil including a stylet coil lumen, the stylet coil extending within the elongated body, the stylet coil being configured to selectively accept a stylet within the stylet coil lumen;
• and
• a conductor assembly including a plurality of insulated electrical conductors braided in a tubular braided configuration around the stylet coil, the tubular braided configuration including the plurality of insulated electrical conductors braided with one another, the conductor assembly including an inner lumen with a diameter greater than an outside diameter of the stylet coil, wherein the inner lumen of the conductor assembly is separated from the stylet coil by a gap with the elongated body in a relaxed condition, wherein, with axial elongation, the elongated body, in an elongated configuration, includes a reduced inner diameter of the conductor assembly, the reduced inner diameter being smaller than an inner diameter of the conductor assembly with the elongated body in the relaxed configuration, the axial elongation of the elongated body closing the gap and causing the conductor assembly to constrict around the stylet coil.

An apparatus comprising:

• an elongated body;
• a stylet coil including a stylet coil lumen, the stylet coil extending within the elongated body;
• and
• a conductor assembly including a plurality of insulated electrical conductors braided with one another in a tubular braided configuration around the stylet coil, the conductor assembly including an elongated inner lumen having an unelongated inner diameter that is greater than an outside diameter of the stylet coil with the conductor assembly in an unelongated configuration, the elongated inner lumen of the conductor assembly being separated from the stylet coil by a gap with the conductor assembly in the unelongated configuration, wherein axial elongation of the conductor assembly into an elongated configuration provides an elongated inner diameter of the conductor assembly that is less than the unelongated inner diameter to close the gap and cause the conductor assembly to constrict around the stylet coil.
