1. An implantable device, comprising:
- (a) a substantially inelastic shell comprising an outer surface and an inner surface, wherein the shell is curved such that the inner surface is substantially concave;
(b) a flexible membrane sealingly coupled to the shell, wherein an inflatable space is defined between the flexible membrane and the inner surface, wherein the flexible membrane has a deflated configuration and an inflated configuration, wherein the inflated configuration is a smoothly curved ovate projection;
(c) a port associated with the outer surface of the shell, wherein an interior portion of the port is in fluid communication with the inflatable space; and
(d) a wrap coupled to the outer surface of the shell, the wrap configured to be removeably positionable around a portion of a patient'"'"'s artery such that the flexible membrane is configured to be held against the artery, wherein the device has no other component or structure for holding the device against the artery,wherein the shell is configured to extend around only a portion of the circumference of the artery.

8. An implantable device, comprising:
-
(a) a substantially inelastic shell comprising an outer surface and an inner surface, wherein the shell is curved such that the inner surface is substantially concave; (b) a flexible membrane sealingly coupled to the shell, wherein an inflatable space is defined between the flexible membrane and the inner surface, wherein the flexible membrane has a deflated configuration and an inflated configuration, wherein the inflated configuration is a smoothly curved oval projection; (c) a port associated with the outer surface of the shell, wherein an interior portion of the port is in fluid communication with the inflatable space; and (d) a wrap coupled to the outer surface of the shell, the wrap configured to be removeably positionable around a portion of a patient'"'"'s artery such that the flexible membrane is configured to be held against an outer side of the artery, wherein the device has no other component or structure for holding the device against the artery, wherein the smooth curved oval projection is configured to cause the outer side of the artery to progressively deform substantially without stretching a wall of the artery, wherein the shell is configured to extend around only a portion of the circumference of the artery. - View Dependent Claims (9, 10, 11, 12)
