  • Patent number: 8911469
    Abstract: Ischemia-reperfusion injury commonly results from any surgical procedure requiring stopping of blood supply to an organ followed by reperfusion such as in heart bypass, angioplasty or organ transplant. The invention discloses a method to harness the innate power of repetitive transient ischemia in protecting organs against imminent ischemia-reperfusion, or any patho-physiological insults. This method of optimal remote ischemic preconditioning (ORIP) comprises of utilizing a pair of programmable pneumatic cuffs that inflate/deflate alternately occluding blood circulation to each of the limbs for pre-defined time intervals. The apparatus delivers maximal ORIP dose in shortest possible time either as an EMS procedure during patient transportation to hospital, as elective pre-surgery treatment, or in critical care for preventing multiple-organ-dysfunction-syndrome. ORIP can be self-administered and remotely monitored by clinician especially in chronic patients for homeostasis of malfunctioning target organs.

  • Publication number: 20140343600
    Abstract: Methods for adaptive cuff inflation for the purposes of occluding a limb of a subject include inflating a cuff to a pressure at or above limb occlusion pressure and periodically deflating the cuff to detect amplitude of oscillometric oscillations reaching or exceeding a predetermined threshold, whereby indicating that the cuff pressure has reached an updated systolic blood pressure. Selecting the cuff to be wide enough to define limb occlusion pressure at or below the systolic blood pressure assures that this maneuver does not compromise cessation of blood flow to the limb. Devices are disclosed configured to operate in at least two of the following three operating modes: a tourniquet mode, a remote conditioning mode and a blood pressure monitoring mode.

  • Publication number: 20140343599
    Abstract: A system for reducing the damaging effects of radiant energy, blast, or concussive events includes applying pressure to at least one jugular vein to reduce the egress of blood from the cranial cavity during or before the incidence of the imparting event. Reducing blood outflow from the cranial cavity increases intracranial volume and/or pressure of the cerebrospinal fluid to reduce the risk of traumatic brain injury and injuries to the spinal column. Reducing blood outflow further increases the intracranial pressure and volume, and thereby increases the pressure and volume of the cochlear fluid, the vitreous humor and the cerebrospinal fluid to thereby reduce the risk of injury to the inner ear, internal structure of the eye and of the spinal column.
