Adaptors, cannulas, caps, tube couplers, and systems thereof provide endovascular access through an established ECLS system. Adaptors having curved or angled shafts navigate right angle side ports of standard bypass cannulas and permit hemostatic introduction and direction of an intervention device to the axial flow path of the cannula lumen and bypass system. A modified cannula having an angled side port is also provided for use as an arterial cannula. A cap having an occluding surface may be inserted into the angled side port to prevent blood from stagnating in the angled side port. A tube coupler is also provided having an access port, such as an angled access port, and may be spliced into an established bypass system for vascular access point. Multiple couplers can be used to provide multiple access points. The adaptors and occlusive cap are interchangeable with each other and with secondary circuits.

A method for filling and venting a device for extracorporeal blood treatment is disclosed, such as a patient module in a heart-lung machine, without attached patient. A filling liquid from a filling liquid container located higher than the device flows by gravity via a venous side of the system into a reservoir and flows onwards into a blood pump located at the lower end of the reservoir, wherein a first controllable valve (HC1) for a venting line of a filter is opened and, after the response of an upper filling level sensor in the reservoir, is closed. An upper level of the filter is positioned higher than the upper filling level sensor, and a start-stop motion of the blood pump is performed, as a result of which a stepped flooding of the filter is made providing for an advantageous de-airing of the device.

An extracorporeal system for lung assist includes a system housing, which includes a blood flow inlet and a blood flow outlet and a fiber bundle housing movably positioned within the system housing. The fiber bundle housing includes a gas inlet and a gas outlet. A fiber bundle is in operative connection with the fiber bundle housing. The fiber bundle includes a plurality of hollow gas permeable fibers, wherein lumens of the plurality of hollow gas fibers are in fluid connection with the gas inlet at a first end thereof and in fluid connection with the gas outlet as a second end thereof. The system further includes an actuator to impart oscillatory motion to the fiber bundle housing and thereby to the fiber bundle.

A system for supporting the blood gas exchange by means of mechanical ventilation and extracorporeal blood gas exchange comprises a ventilation device for mechanical ventilation of the lungs of a patient, and an ECLS device for the extracorporeal blood gas exchange, wherein the ventilation system is designed to perform mechanical respiratory support by the ventilation device on the one hand and an extracorporeal blood gas exchange by the ECLS device on the other hand in coordinated, automated manner in order to support the gas exchange in the blood circulation of the patient, wherein the ECLS device sets a level of the extracorporeal blood gas exchange, and the ventilation device, on the basis of the level of the extracorporeal blood gas exchange set by the ECLS device, adjusts in automated manner to a level of the mechanical respiratory support.

Microfluidic gas exchange devices may include one or more exchange modules (100), wherein each exchange module includes: a first layer comprising: one or more primary inlets (108); a first capillary network connected to the one or more primary inlets, wherein the first capillary network extends radially outward from at least one of the one or more primary inlets, and wherein the first capillary network includes one or more injection branches (104) and a series of microchannels (106); and one or more primary outlets connected to the first capillary network; and a second layer that includes a semipermeable membrane.

A system and methods are described for improving the management of ischemic cardiac tissue during acute coronary syndromes. The system combines a catheter-based sub-system which allows for simultaneous balloon dilation of a coronary artery and infusion of a carefully controlled perfusate during percutaneous coronary intervention. The system allows for modulation of levels of oxygen at the time of percutaneous intervention. In addition, catheters and systems are provided for administration of fluids with modified oxygen content during an intervention that incorporate upstream flow control members to compartmentalize the perfusion of the target coronary artery and the remainder of the heart.

A blood processing apparatus includes an optional heat exchanger and a gas exchanger disposed within a housing. In some instances, the gas exchanger can include a screen filter spirally wound into the gas exchanger such that blood passing through the gas exchanger passes through the screen filter and is filtered by the spirally wound screen filter a plurality of times.

An extracorporeal blood cooling or heating circuit includes an intravenous catheter for withdrawing a patient's blood coupled to a combined pump/heat exchanger device. One or more sensors are provided upstream and/or downstream of the pump/heat exchanger device for measuring pressure, temperature, fluid flow, blood oxygenation, and other parameters. A controller is operatively coupled to the pump/heat exchanger device and the one or more sensors to control the speed of the pump inside the pump/heat exchanger device and regulate the blood temperature by controlling the operation of the heat exchanger. The combined pump/heat exchanger device includes a housing having at least one inlet and at least one outlet, a pump portion defining a blood circuit inside the housing, and a heat exchanger portion contained within the housing for selectively heating or cooling the blood.

Improvements introduced in adsorption filter for inhaled halogenated anesthetics for cardiopulmonary bypass. It relates to an adsorption filter (10) of the type pertaining to the field of medical devices, more specifically, used to adsorb inhaled halogenated anesthetics that are eliminated through the output of the membrane oxygenators (20) of the cardiopulmonary bypass circuit (CPB); said filter (10) contains a hollow reservoir (11) for preservation of adsorber elements (ED) of the activated charcoal type (30), said reservoir (11) being of tubular cylindrical form, and it receives on one of the free extremities (11a) a cover (12) whose internal diameter (d1) is greater than the external diameter (d2) of the cylindrical reservoir (11), so as to produce an access chamber (C1) for the input of the inhaled anesthetic (Al) that, in turn, penetrates through a tubular member (12a) in the central portion of the cover (12), where a tube (Tb1) for connection with the oxygenator device (20) is installed, said tube (Tb1) allowing the input of the gas (Al) into the filter (10) for decontamination; on the same extremity (11a) and in the peripheral wall (11b) are made openings (11c) intended for the input of the inhaled anesthetic (Al) after input in the chamber (C1), initiating the ingression in the chamber (C2) of the cylinder (11) endowed with adsorber element (ED).

Described herein are devices, systems, and methods used to assess an organ or organ system and determine a course of treatment for said organ, organ system, and/or patient.
