In a method, system and device a member is provided around an aneurysm enabling treatment and monitoring of the aneurysm. In accordance with one embodiment the device is adapted to be adjusted postoperatively. Hereby the treatment can be efficiently carried out without having to perform surgery when adjusting the member.

A remote ischemic conditioning system may be integrated with other medical devices or apparatus so that cycles of remote ischemic conditioning may be performed on a patient before, during and/or after performance of another medical procedure. In one embodiment, a remote ischemic conditioning system may be integrated with a surgery table. In another embodiment, a remote ischemic conditioning system may be integrated with an automated external defibrillator, or an automated external defibrillator/monitor. Integration of the remote ischemic conditioning system with the surgical table or the automated external defibrillator allows the remote ischemic conditioning system to be powered by the power source for the table or the automated external defibrillator, and/or to be controlled by a control panel disposed on the table or the automated external defibrillator. Also, data from the controller for the remote ischemic conditioning system may be received and stored in the controller for the table or the automated external defibrillator. This data may be displayed on a monitor for the table or defibrillator and/or transmittal to a hospital or heart center.

A venipuncture device may be used for assisting a healthcare provider identify and locate a blood vessel in a patient. According to embodiments, heat is applied to a selected venipuncture site on the patent's limb. A pressure cuff constricts the limb proximal to the venipuncture site, thereby partially occluding blood flow through the blood vessel and engorging the blood vessel and making it more visible to the healthcare provider. The healthcare provider may then carry out various operations on the patient, including but not limited to drawing blood and insertion of an intravenous line.

A method of pressure control in the pneumatic compression bandage and a pneumatic compression bandage includes a cuff with a chamber to be filled with a pressurized fluid. The device has a harness to fasten the cuff in the wound area and a control and pumping unit (6) connected pneumatically to the chamber in the cuff via a hose. The unit includes an electrical pump, an electromechanical valve connected electrically with the unit, a pressure sensor connected electrically with the unit (6). The controller of the pressure in the cuff chamber is of the PID type, including a proportional, integral and derivative modules, to control the electric pump to increase pressure in the cuff chamber and to control the valve to reduce pressure in the cuff chamber.

The invention provides methods for reducing traumatic injury through the use of ischemic conditioning.

The disclosure provides neck collar devices and systems for the mitigation and prevention of traumatic brain injury, including concussion. Specifically disclosed are adjustable collars and systems, and collars having certain pressure sensing devices.

Disclosed is a method and apparatus for regulating tourniquet cuff pressure based on a personalized tourniquet pressure (PTP) to facilitate safe performance of a surgical procedure. The apparatus includes a dual-purpose tourniquet cuff adapted to encircle a region of a patient limb to provide both a sensor during a pre-surgical time period and an effector during a surgical time period. An effector module communicates pneumatically with an inflatable bladder of the cuff for maintaining pressure in the bladder near a PTP during the surgical time period to safely stop penetration of arterial blood past the cuff. A pulsation sensor that communicates pneumatically with the inflatable bladder during the pre-surgical time period senses and characterizes pressure pulsations that are indicative of penetration of arterial blood into the region of the limb encircled by the cuff. A PTP estimator is responsive to the pulsation sensor for producing an estimate of the PTP, such that the estimate of the PTP is a function of the sensed pulsations.

A system for diverting emboli within a patient can include a device that detects a presence of emboli in a first blood vessel of a patient. A compression member can be aligned with a second blood vessel of the patient when a collar supporting the compression member is positioned at least partially around a portion of the patient. In response to the detection device, a controller can actuate the compression member, when the presence of emboli is detected, from an unactuated state to an actuated state in which at least a portion of the compression member (i) is closer to the second blood vessel than while in the unactuated state and (ii) compresses and limits blood flow through the second blood vessel.

An inflatable belt 100 for use in a BFR system with an outer belt material 102 hermetically sealed to an inner belt material 101 along a perimeter, thereby forming at least one inflatable chamber 103, the inflatable chamber having an input port 104 for accepting a gas into the chamber, the inflatable belt further comprising a first fastening means 110 in communication with the outer belt material, for attaching to a second fastening means 111 in communication with the outer belt material, thereby locking a circumference of the inflatable belt, when wrapped around a user's limb.

A blood pressure cuff includes a support band that is selectively reconfigured between a flexible standby configuration and a measurement configuration. A blood pressure cuff includes an inflatable bladder, a support band, and a control unit. The support band is attached to and surrounds the inflatable bladder. The support band is reconfigurable, in response to an input from the control unit, from a standby configuration for between blood pressure measurements to a measurement configuration for constraining the inflatable bladder while the inflatable bladder is in an inflated state during a blood pressure measurement. The control unit includes a bladder pump for inflation of the inflatable bladder during a blood pressure measurement and controls the selective reconfiguration of the support band.
