A device for treating an aneurysm of a human or mammal patient, wherein the aneurysm may self-expand. The device comprising an implantable member adapted to be placed in around an outside of a blood vessel having the aneurysm to enable the implantable member to exercise a pressure on the outside of the blood vessel having the aneurysm. The device further comprising a measuring device or sensor for measuring or sensing an expansion of the aneurysm and a monitoring system adapted to monitor the expansion of the aneurysm based on a signal received from the measuring device or sensor.

Methods and apparatus are provided for assessing endothelial function in a mammal. In certain embodiments the methods involve using a cuff to apply pressure to an artery in a subject to determine a plurality of baseline values for a parameter related to endothelial function as a function of applied pressure (P.sub.m); b) applying a stimulus to the subject; and applying external pressure P.sub.m to the artery to determine a plurality of stimulus-effected values for the parameter related to endothelial function as a function of applied pressure (P.sub.m); where the baseline values are determined from measurements made when said mammal is not substantially effected by said stimulus and differences in said baseline values and said stimulus-effected values provide a measure of endothelial function in said mammal.

A device for performing blood flow restriction training during the day, integrated with a garment, and controllable to apply a desired compression level to a range of muscles with the intent on improving the health and fitness of a user doing normal daily activities.

Systems and methods and devices are provided for treating conditions such as heart failure and/or pulmonary hypertension by at least partially occluding flow through the superior vena cava for an interval spanning multiple cardiac cycles. A catheter with an occlusion device is provided along with a controller that actuates a drive mechanism to provide at least partial occlusion of the patient's superior vena cava, which reduces cardiac filling pressures, and induces a favorable shift in the patient's Frank-Starling curve towards healthy heart functionality and improved cardiac performance. The occlusion device may include a lumen obstructed by a relief valve that may permit fluid flow through the occlusion device to release an excessive build-up of pressure.

The present disclosure provides for specific shapes and combinations of the compression members amenable to the safest, yet most effective compression of the carotid and vertebral arteries aimed at prevention of embolic stroke. An associated method of achieving an optimal compression of said arteries for the purpose of stroke prevention is provided.

A device for use in preventing stroke is provided, The device may include an expandable member that expands from a non-expanded configuration to an expanded configuration. The expandable member is located at a neck of a patient. An associated method is provided.

A simple auto electronic tourniquet includes a cuff, a pressurizing means for gradually raising the internal pressure of the cuff, a depressurizing means for gradually decreasing the internal pressure of the cuff, a pressure detecting means for detecting the internal pressure of the cuff, a target pressure setting means for setting the internal pressure of the cuff to a target pressure, a pressure control means for controlling the internal pressure of the cuff so that it gets close to the approximate value of the target pressure, and a notifying means for notifying that venipuncture is performable. In order to avoid excessive pressures, long-time performance of avascularization, sudden rise of pressure, which may cause patients to feel stressed, the width of the cuff of the tourniquet of the present invention shall be 75 mm or less, and more preferably in the range between 10 mm and 60 mm.

A brain injury reduction system provides a protective measure to reduce severity of brain injury caused by collision or blast. A sensing device of the system detects an impending or occurring event (e.g., collision or blast) in an environment surrounding the individual and sends information about the event to a controller of the system. The sensing device can be stationary or moves with the individual. Based on the information, the controller determines whether the event will likely cause brain injury to the individual. If so, the controller sends an instruction to an actuation device of the system to activate the protective measure. The actuation device uses transcutaneous electrodes to electrically simulate glottis closure and contraction of the abdominal musculature to induce a Valsalva-like maneuver. The Valsalva-like maneuver can increases the stiffness of the brain tissues in the intracranial compartment, and thus reduces the susceptibility of the brain tissues to deformation.

A passive implantable medical device for controlling a flow of fluid through a tube within a patient includes a first component and a second component movably coupled to one another and defining a central passage configured for receiving a portion of the tube therethrough. The passive implantable medical device is configured for moving between a first configuration and a second configuration to constrict a portion of the tube. An active implantable medical device for controlling a flow of a first fluid through a tubing includes a flow control cuff comprising a stiff outer wall and a deformable inner wall which defines a central opening sized such that the tubing can extend therethrough. A pump is configured to modulate a pressure of the second fluid within the interior space to apply a constrictive force to a section of the tubing.

A cooling tourniquet system (100) includes a cooling component (110) with a tourniquet (112) at a proximal end and a control component (130). The cooling component includes a cooling pad (120) configured to be wrapped about an extremity, and a cover (111) that wraps around the cooling pad. An inner surface of the cooling pad includes one or more sensors for detecting the temperature of the extremity. The tourniquet is configured to be applied to the extremity to stop blood flow distally from the tourniquet. The control component receives temperature data from the sensors, and controls the cooling pad based on the received data rapidly cooling the extremity at depth, without causing frostbite tissue damage. In one embodiment the control component circulates a chilled fluid with a time-varying temperature profile through passages in the cooling pad. In an embodiment the cover includes an air bladder that holds the cooling pad in contact against the extremity.
