Abstract

Apparatus and methods are described including an implantable device shaped to define (a) at least two artery-contact regions, the artery-contact regions comprising struts that are configured to stretch an arterial wall by applying pressure to the arterial wall, and (b) at least two crimping regions that comprise locking mechanisms configured to prevent the crimping regions from becoming crimped due to pressure from the wall of the artery on the artery-contact regions. The crimping regions are configured to be crimped during insertion of the device, via a catheter, by the locking mechanisms being unlocked during insertion of the device. Other embodiments are also described.

Claims

1. Apparatus, comprising:

an implantable device having four artery-contacting strut portions, the implantable device defining a polygonal cross-section from a proximal end thereof to a distal end thereof with the artery-contacting strut portions being vertices thereof,

wherein the artery-contacting strut portions are parallel to each other,

wherein the implantable device is configured to change a shape of a blood vessel when placed therein, and

wherein, when the implantable device is in a fully expanded configuration, each of the artery-contacting strut portions are disposed at a first distance from a first directly circumferentially adjacent artery-contacting strut portion, and at a second distance from a second directly circumferentially adjacent artery-contacting strut portion, the second distance being greater than the first distance.

2. The apparatus according to claim 1, wherein a ratio of the second distance to the first distance is between 1.1:

1 and 5;

1.

3. The apparatus according to claim 2, wherein the ratio of the second distance to the first distance is between 1.5:

1 and 3;

1.
