1. A method of treating a disease related to hypertension of a subject, the subject having baroreceptors and a central nervous system responsive to the baroreceptors, comprising:

  • providing a passive flexible element having a non-circular cross-section, the passive flexible element comprising a first non-circular flexible end element and a second non-circular flexible end element, the first non-circular flexible end element coupled to the second non-circular flexible end element with three or more rods extending therebetween,coupling the passive flexible element having the non-circular cross-section to a carotid artery of the subject in a vicinity of the baroreceptors of the subject, by implanting the passive flexible element within the carotid artery, the passive flexible element being configured to flex passively in coordination with the cardiac cycle; and

    facilitating, with the passive flexible element, an assumption of a non-circular cross-sectional shape by the carotid artery in the vicinity that is less circular than a shape of the carotid artery in the vicinity when the passive flexible element is not coupled to the carotid artery, wherein passive flexure of the first non-circular flexible end element and the second non-circular flexible end element in coordination with the cardiac cycle of the subject stimulates the baroreceptors to transmit signals to the central nervous system and treats the disease related to hypertension.
