1. A method, comprising:
- identifying a subject as suffering from hypertension; and
in response to the identifying,(a) increasing a radius of curvature of a first set of at least three regions of an arterial wall of the subject at a given longitudinal location, while(b) allowing the first set of regions of the arterial wall to pulsate, byimplanting a device inside the artery at the longitudinal location such that the device applies pressure to the arterial wall at a second set of at least three regions of the artery, but does not contact the first set of regions, the first set of regions and the second set of regions alternating with each other.

Abstract
Apparatus and methods are described, including identifying a subject as suffering from hypertension. In response to the identifying (a) a radius of curvature of a first set of at least three regions of an arterial wall of the subject is increased at a given longitudinal location, while (b) allowing the first set of regions of the arterial wall to pulsate. A device is implanted inside the artery at the longitudinal location such that the device applies pressure to the arterial wall at a second set of at least three regions of the artery, but does not contact the first set of regions, the first set of regions and the second set of regions alternating with each other. Other embodiments are also described.

20. Apparatus for treating hypertension of a subject, comprising:
an implantable device shaped to define at least three separate artery-contacting surfaces, and configured to; (a) increase a radius of curvature of a wall of the artery at a first set of at least three regions of the arterial wall at a given longitudinal location, while (b) allowing the first set of regions of the arterial wall to pulsate at the longitudinal location, by the device being implanted inside the artery at the longitudinal location such that the artery-contacting surfaces contact a second set of at least three regions of the arterial wall, but do not contact the first set of regions of the arterial wall, the first set of regions and the second set of regions alternating with each other. - View Dependent Claims (21, 24, 31, 32, 34)

35. A method, comprising:
-
identifying a subject as suffering from hypertension; and in response to the identifying, (a) increasing strain at a first set of regions of an arterial wall of the subject at a given longitudinal location, (b) while maintaining, at a given stage in a cardiac cycle of the subject, a cross-section of the artery at the longitudinal location that is at least 20 percent of the cross-section of the artery at the longitudinal location, at the given stage in the cardiac cycle, when the device is absent, by implanting a device outside the artery at the longitudinal location such that the device applies pressure to the arterial wall at the first set of regions of the arterial wall, but does not contact the arterial wall at at least a second set of regions of the arterial wall at the longitudinal location, the first set of regions and the second set of regions alternating with each other. - View Dependent Claims (39, 40, 41, 42, 43, 44, 46, 48)
