In various examples, a therapy delivery element for at least partial implantation in a patient includes an elongate body. The elongate body includes a substantially tubular braided structure that extends from proximate a proximal end to proximate a distal end of the elongate body. A substantially tubular structure is coaxially disposed with respect to the braided structure. The tubular structure is attached to the braided structure proximate a distal braid end. At least a majority of the braided structure proximal from the distal braid end is unattached to the tubular structure.
