An extracorporeal system for lung assist includes a housing which includes a blood flow inlet in fluid connection with a pressurizing stator compartment, a fiber bundle compartment in fluid connection with the pressurizing stator compartment via a flow channel within the housing, and a blood flow outlet in fluid connection with the fiber bundle compartment. An impeller is rotatably positioned within the pressurizing compartment. The system further includes a fiber bundle within the fiber bundle compartment. A plurality of hollow gas permeable fibers of the fiber bundle extend generally perpendicular to the direction of bulk flow of blood through the fiber bundle compartment from the flow channel to the blood flow outlet.

A dual lumen drainage cannula configured for use in a VA ECMO system includes a first drainage tube having a proximal end, a distal end, and at least one aperture in at least one wall of the first drainage tube proximate to the distal end of the first drainage tube, and a second drainage tube having a proximal end, a distal end, and at least one aperture in at least one wall of the second drainage tube proximate to the distal end of the second drainage tube. The first drainage tube passes through the second drainage tube. The dual lumen drainage cannula also includes a sleeve positioned adjacent to an interior wall of the second drainage tube. The sleeve is formed of a flexible material so as to be expandable and collapsible within the second drainage tube.

A cannulation coupler has a primary branch comprising a retaining feature. The cannulation coupler also has a side inflow branch in communication with the primary branch. The cannulation coupler further has an outflow branch in communication with the primary branch and in communication with the side inflow branch. An adjustable cannulation assembly is also disclosed, having a cannulation coupler, an outer cannula, and an inner cannula. The cannulation coupler has 1) a primary branch comprising a retaining feature, 2) a side inflow branch in communication with the primary branch, and 3) an outflow branch in communication with the primary branch and in communication with the side inflow branch. The outer cannula is coupled to the primary branch. The inner cannula is coupled to the side inflow branch, wherein: 1) the inner cannula also passes through the primary branch; and 2) the inner cannula is coaxially slidable within the outer cannula.

The invention pertains to a medical device: an ECMO (extracorporeal membrane oxygenation) catheter which can be used during right heart and lung failure. It pertains to a dual lumen catheter with a single port of entry which when in place bypasses the right heart and lungs while completing the veno-arterial circuit.

A mount interface is described that includes a latch; and a latching assembly configured to receive the latch so as to lock the latch at a set position with respect to the latching assembly, wherein the latching assembly includes a housing provided with an irregular orifice configured to receive the latch; a first plug disposed in the housing so that a first portion of the irregular orifice overlies the first plug; and a second plug disposed in the housing adjacent the first plug so that a second portion of the irregular orifice overlies the second plug. Such a mount interface provides rapid and secure locking of a latch to the latching assembly.

A device for establishing venous inflow to a blood reservoir of an extracorporeal blood circulation system includes a restricting unit for gradually closing a venous inflow line and a vacuum unit for supplying vacuum to the blood reservoir. The device includes a control unit that supplies a first actuating signal to the restricting unit for restricting venous inflow to the blood reservoir and supplies a second actuating signal to the vacuum unit for establishing a degree of vacuum within the blood reservoir.

A system for lung assist includes a plurality of fiber bundle sections which includes a fiber bundle housing defining a fiber bundle compartment with a fiber bundle positioned within. The fiber bundle includes a plurality of hollow gas permeable fibers. The fiber bundle housing further includes a gas inlet in fluid connection with the fiber bundle housing and in fluid connection with inlets of the plurality of hollow gas permeable fibers, a gas outlet in fluid connection with the housing and in fluid connection with outlets of the plurality of hollow gas permeable fibers, and a blood outlet in fluid connection with a first end of the fiber bundle. The system further includes a base section including a housing including a pressurizing compartment, a pressurizing mechanism within the pressurizing compartment, a blood inlet in fluid connection with the pressurizing compartment and a conduit.

The disclosure provides a method of placing a cardiac drainage cannula into a patient's heart. In some embodiments, the method comprises the steps of (a) inserting the cannula percutaneously into an internal jugular vein, (b) advancing the cannula through the internal jugular vein and into the right atrium of the heart, and (c) advancing the cannula through the atrial septum into the left atrium of the heart. Further aspects of the disclosure provide a method of draining blood from the left atrium or left ventricle of a patient's heart using a cardiac drainage cannula. The disclosure also provides a cardiac drainage cannula and a mechanical circulatory support system.

An artificial lung in a circulation apparatus can be monitored and be maintained in a safe condition without manual assistance. As an extracorporeal circulation mode starts, it is determined first whether or not gas exchange of the artificial lung is carried out within a normal range, based on oxygen concentration which is detected by an oxygen sensor positioned at a downstream place in the artificial lung. If the gas exchange is carried out within the normal range, an estimated value for gas supply volume of a gas blender is maintained. When oxygen concentration exceeding the normal range is detected, the gas blender is controlled so as to revise the gas supply volume downward. In addition, when oxygen concentration falls below the normal range, the gas blender is controlled so as to revise the gas supply volume upward.
