Occlusive cuff

An overlapping occlusive cuff having secondary safety securing means for improved safety, comprising:

• a) an inflatable bladder for encircling a limb, wherein the length of the bladder is selected to be sufficient for the bladder to encircle the limb at a desired location and have portions that overlap circumferentially around the limb;
• b) bladder securing means for securing the overlapping bladder in a substantially circumferential direction around the limb with the bladder inflated to a pressure sufficient to occlude flow in blood vessels in the limb encircled by the bladder;
• and
• c) secondary safety securing means superimposed over the overlapped portions of the bladder and superimposed over the bladder securing means, the secondary safety securing means extending in a substantially circumferential direction for securing the overlapping bladder in a substantially circumferential direction around the limb independently of the bladder securing means such that the bladder remains overlapped and secured in a substantially circumferential direction if the bladder securing means is ineffective while the bladder is inflated.
