Abstract
Apparatus (20) is provided including an inflatable bladder (40), adapted to be coupled to a blood vessel (22) of a subject (18) carrying oxygenated blood, such that an interior of the bladder (40) is in fluid communication with the blood. The apparatus also includes a piston (48) in mechanical communication with the bladder (40); a motor (60), adapted to synchronize contraction and expansion of the bladder (40) with a cardiac cycle of the subject (18) by applying a motor force to the piston (48); and a spring (54), adapted to apply a spring force to the piston (48).

Apparatus comprising:
- an inflatable bladder, comprising:
- an inner layer and an outer layer, which define a chamber therebetween, the inner layer defining an interior of the bladder;
- a biocompatible substantially non-conductive fluid, contained within the chamber;
- two or more electrodes, in contact with the substantially non-conductive fluid;
- and
- a current sensing unit, coupled to the electrodes and adapted to sense current flow between at least two of the electrodes,
- wherein the bladder is adapted to be implanted in a subject such that the interior of the bladder is in fluid communication with blood of a blood vessel of the subject.
41-104. (canceled)
A method for using an inflatable bladder, comprising:
- coupling the bladder to a blood vessel of a subject carrying oxygenated blood, such that an interior of the bladder is in fluid communication with the blood;
- synchronizing contraction and expansion of the bladder with a cardiac cycle of the subject by applying a motor-generated force to a piston in mechanical communication with the bladder;
- and
- applying a spring-generated force to the piston.
