1. A device for remote ischemic conditioning comprising:
- an inflatable cuff configured to encircle a limb of a subject;
a controller removably attached to the cuff, wherein the controller comprises;
a manifold configured to provide fluid communication between the controller and the cuff;
an outlet in fluid communication with the manifold and in removable fluid communication with the inflatable cuff; and
a control circuit configured to implement a remote ischemic conditioning treatment protocol; and
a controller attachment section joined to the cuff, the controller attachment section having a bottom surface that substantially conforms to an outer surface of the cuff, wherein the controller is removably attached to the cuff by selective attachment to the controller attachment section disposed on the cuff, the controller attachment section further comprising;
an upper surface for supporting the controller in an attached state;
an upstanding wall surrounding the upper surface;
a tab mounted at one end of the upper surface and including a projecting edge spaced from the upper surface, the projecting edge facing outwardly toward the upstanding wall; and
bosses disposed on the upstanding wall on the opposite side of the controller attachment section from the tab;
wherein the controller further comprises a slot that is disposed between a body of the controller and an outer band, and wherein the device is arranged such that when the controller is attached to the controller attachment section, an upper portion of the tab is pushed inwardly away from the upstanding wall so that the tab passes through the slot, and the bosses extend into corresponding recesses provided in the controller body.

10. A device for remote ischemic conditioning comprising:
-
an inflatable cuff configured to encircle a limb of a subject; a controller removably attached to the cuff, wherein the controller comprises; a manifold configured to provide fluid communication between the controller and the cuff; an outlet in fluid communication with the manifold and in removable fluid communication with the inflatable cuff; and a control circuit configured to implement a remote ischemic conditioning treatment protocol; and a controller attachment section joined to the cuff, the controller attachment section having a bottom surface that substantially conforms to an outer surface of the cuff, wherein the controller is removably attached to the cuff by selective attachment to the controller attachment section disposed on the cuff; wherein cuff pressure is controllable by selectively opening a valve of the controller in response to a command from control circuitry of the control circuit; wherein the controller attachment section provides fluid communication between the controller and a bladder of the cuff via a structure that includes a conduit that has a female section constructed and arranged to mate with the controller outlet and a male section that is constructed and arranged to mate with a valve of the bladder of the cuff; and wherein the controller outlet has an outer dimension at an end spaced from the controller, and the female section of the conduit has an upper opening that is configured to receive the end of the controller outlet, a cross-sectional size of the upper opening of the female section being greater than the outer dimension of the controller outlet and greater than an inner dimension of the male section. - View Dependent Claims (11, 12)
