WEARABLE MODULAR EXTRACORPOREAL LIFE SUPPORT DEVICE FOR MOBILE TREATMENT OF SINGLE AND MULTIORGAN FAILURE
In one exemplary embodiment, a wearable extracorporeal life support device includes a catheter fluidly connected to a pump and first and second modular extracorporeal life support components. The device may also be configured to be attached to a garment. The pump and the first and second modular extracorporeal life support components may be fluidly connected in series. The pump and the first and second modular extracorporeal life support components may also be fluidly connected in parallel. The first modular extracorporeal life support component may be a lung membrane and the second modular extracorporeal life support component may be a dialysis membrane.
SYSTEM AND METHOD FOR CARDIOPULMONARY BYPASS USING HYPOBARIC OXYGENATION
A system for cardiopulmonary bypass, including: a cardiopulmonary bypass reservoir configured to store a blood; a pump in fluid communication with the cardiopulmonary bypass reservoir configured to provide pressure to the system; an oxygen source including a pressure regulator configured to regulate an oxygen pressure; an oxygenator fluidly connected to the pressure regulator of the oxygen source via an sweep gas inlet, wherein the sweep gas inlet is configured to have a subatmospheric pressure and the oxygenator is configured to oxygenate the blood; a vacuum regulator fluidly connected to the oxygenator via an sweep gas outlet, and configured to provide the subatmospheric pressure; a flow restrictor fluidly connected to the sweep gas inlet and configured to allow for a pressure drop from the oxygen source to the oxygenator; and an arterial filter fluidly connected to a blood outlet of the oxygenator and to the cardiopulmonary bypass reservoir.
VAVD regulator contamination and condensation control
Embodiments include a vacuum assisted venous drainage (VAVD) system, including a regulator valve assembly configured to facilitate application of vacuum to a reservoir; a control unit configured to control the regulator valve assembly to facilitate controlling application of the vacuum; at least one pressure sensor coupled to the reservoir and configured to obtain pressure measurements of pressure in the reservoir; a heating element configured to heat the regulator valve assembly to a target temperature; and at least one temperature sensor configured to determine a temperature of the regulator valve assembly.
Systems, devices, and methods for extracorporeal removal of carbon dioxide
Systems, devices, and methods are provided for removing carbon dioxide from a target fluid, such as, for example, blood, to treat hypercarbic respiratory failure or another condition. A device is provided including first and second membrane components for removing dissolved gaseous carbon dioxide and bicarbonate from the fluid, which can be done simultaneously. The device can be in the form of a cartridge configured for use in a dialysis system. A method of treatment is also provided, involving drawing blood from a patient and bringing the patient's blood in contact with a first membrane component having a sweep gas passing therethrough, and a second membrane component having a dialysate passing therethrough. The dialysate's composition can be selected such that charge neutrality is maintained.
Oxygenator with a housing wall
An oxygenator with a housing wall, which delimits a housing space with a blood inlet and a blood outlet, a gas inlet and a gas outlet, has a heating element which is arranged in the oxygenator between blood inlet and blood outlet in order to control the temperature of blood flowing through the housing space. For this purpose, the oxygenator has a radiation source and a receiver. The radiation source can be an infrared emitter and the receiver a matte-black surface, or the radiation source is an induction coil and the receiver has a material capable of induction. In a method for regulating the heat output on a heating element of an oxygenator, the through-flow of the blood through the oxygenator and the power of a pump acting on the through-flow are measured, and the heating power is adjusted in accordance therewith.
Expandable ECMO extension cannula system
An extension cannula and in-line connector for use with a conventional ECMO return cannula is provided. The extension cannula includes a flexible conduit transitionable between a collapsed insertion state and an expanded deployed state when in communication with blow flow from an ECMO machine via the ECMO return cannula. The extension cannula may be positioned through a conventional ECMO return cannula such that the proximal end of the flexible conduit is disposed within and proximal to the end of the ECMO return cannula, while the distal end of the flexible conduit is disposed in a patient's thoracic aorta to deliver oxygenated blood directly to the patient's thoracic aorta via one or more pores at the distal region of the flexible conduit to improve cerebral oxygenation, maintain systemic arterial pulsatility, and reduce the potential for end-organ injury.
DUAL CHAMBER BLOOD RESERVOIR
A blood reservoir may be used in combination with other elements such as a heart lung machine (HLM), oxygenator, heat exchanger, arterial filter and the like to form an extracorporeal blood circuit that may be employed in a procedure such as a bypass procedure. The blood reservoir may be configured to receive, filter and store blood from a number of sources including vent blood (from within the heart), venous blood (from a major vein), purge blood (from a sampling line) and cardiotomy or suction blood (from the surgical field).
DEVICE FOR TREATING AN INDIVUDUAL SUFFERING FROM CARDIAC INSUFFICIENCY, CARDIAC ARREST, CIRCULATORY ARREST OR STROKE
The invention relates to a device for treating an individual suffering from cardiac or circulatory arrest or from a stroke, comprising a blood withdrawal device (BE) that is applied to the individual (P), an analysis unit (BA) which is directly or indirectly connected to the blood withdrawal device for detecting a blood analysis result (BAE) providing at least one characteristic of the blood, directly or indirectly connected to a blood return device (BR) that is applied to the individual (P) and is designed to deliver a substance to the individual via the return device (BR).
BLOOD TREATMENT SYSTEM HAVING BACKFLOW PREVENTION
A medical fluid pumping system includes a medical fluid pump for pumping a process fluid, the medical fluid pump including a first pump chamber, a first inlet valve chamber including a first inlet valve diaphragm, a first outlet valve chamber, a second pump chamber, a second inlet valve chamber including a second inlet valve diaphragm, and a second outlet valve chamber; and a medical fluid chassis operable with the medical fluid pump, the medical fluid chassis including a motive fluid source providing motive fluid at a motive fluid pressure, and wherein the first and second inlet valve diaphragms are configured to actuate from an open to a closed position at a pressure less than the motive fluid pressure to mitigate process fluid backflow through the first and second inlet valves.
Cartridge and method for increasing myocardial function
The present invention relates to a cytopheretic cartridge for use in treating and/or preventing inflammatory conditions that affect myocardial function and to related methods. The cartridge can be used in treating a subject with myocardial dysfunction, such as a subject with chronic heart failure and/or acute decompensated heart failure.
