1. An apparatus for stimulating baroreceptors to treat hypertension of a subject, the apparatus comprising:

  • a selective circumferential pressure applicator, comprising;

    at least two non-contiguous pressure application surfaces that are configured to increase baroreceptor activity of the subject by applying pressure to an artery of the subject at two or more respective non-contiguous regions around a circumference of the artery at a longitudinal site of the artery, such that between the non-contiguous regions, at the longitudinal site;

    there is at least one region of the artery that is more relaxed than in the absence of the apparatus, andthere is at least one region of the artery that is more tense than in the absence of the apparatus; and

    a joint configured;

    to couple the at least two surfaces to each other on the circumference of the artery at the longitudinal site, andfor at least a portion of a cardiac cycle of the subject, not to contact the artery of the subject on the circumference of the artery at the longitudinal sitewherein the at least two non-contiguous pressure application surfaces and the joint are configured to apply forces passively to the artery during systole and diastole of a cardiac cycle in order to increase the baroreceptor activity and maintain blood flow through the artery.
