1. An automatic device for remote ischemic preconditioning treatment, the device comprising:
- a single cuff having a single bladder configured to retract about a limb of a subject;
a controller connected to said cuff, said controller being configured to perform a plurality of sequentially actuated treatment cycles, each cycle comprising;
inflating said cuff to a cuff pressure to occlude blood flow of the subject;
maintaining said cuff pressure at a pressure to occlude blood flow for an ischemic duration of one minute or more; and
deflating said cuff;
wherein said cuff is further configured to be retained about said limb and deliver said remote ischemic preconditioning treatment.

15. An automatic device for remote ischemic preconditioning treatment, the device comprising:
-
a single cuff configured to retract about a limb of a subject, the cuff including a single bladder; an actuator detachably connected to an outer side of said cuff over said limb; a controller that controls said actuator, said controller being configured to perform a plurality of sequentially actuated treatment cycles, each cycle comprising; inflating said cuff to a cuff pressure to occlude blood flow of the subject; maintaining said cuff pressure at a pressure to occlude blood flow for an ischemic duration of one minute or more; and deflating said cuff; wherein after initial activation by a user, said controller is further configured to conduct and complete said entire treatment. - View Dependent Claims (16, 17, 18, 19, 20)

21. A device for remote ischemic preconditioning, the device comprising:
-
a single cuff sized to retract about a limb of a subject, said cuff including a single bladder; a controller connected to said cuff, said controller configured to inflate and deflate said cuff according to a remote ischemic preconditioning treatment protocol, said treatment protocol including a plurality of sequentially actuated treatment cycles, each of said treatment cycles comprising; inflating said cuff to a cuff pressure to occlude blood flow of the subject; maintaining said cuff pressure at a pressure to occlude blood flow for an ischemic duration of one minute or more; and deflating said cuff; wherein during maintaining said cuff pressure at a pressure to occlude blood flow, said controller is further configured to vary said cuff pressure at least once during at least one of said treatment cycles.

22. A device for remote ischemic preconditioning, the device comprising:
-
a cuff sized to retract about a limb of a subject; a controller connected to said cuff, said controller configured to inflate and deflate said cuff according to a remote ischemic conditioning treatment protocol, said treatment protocol including a plurality of treatment cycles, each of said treatment cycles comprising; inflating said cuff to a cuff pressure to occlude blood flow of the subject; maintaining said cuff pressure at a pressure to occlude blood flow for an ischemic duration of one minute or more; and deflating said cuff; wherein during maintaining said cuff pressure at a pressure to occlude blood flow, said controller is further configured to vary said cuff pressure at least once during at least one of said treatment cycles, said controller being further configured to detect a systolic blood pressure of the subject during varying of said cuff pressure. - View Dependent Claims (23, 24)
