The disclosed device, systems and methods relate to a novel catheter, system and methods. Exemplary embodiments comprise a plurality of lumens and balloons for insertion into the aorta and vena cava. These catheters are for use in cardiopulmonary resuscitation and other medical or surgical conditions that require emergency restoration of cerebral and cardiac blood supply.

A hydrophobic filter for filtering an airflow or another gaseous flow in a medical application has a housing encompassing a filter chamber, an inlet port arranged on the housing and forming an inlet opening, an outlet port arranged on the housing and forming an outlet opening, and a hydrophobic structure extending along a plane of extension and separating the filter chamber into an inlet chamber and an outlet chamber. The inlet opening opens into the inlet chamber and the outlet opening opens into the outlet chamber. Herein, the outlet opening opens into the outlet chamber at a first location when viewed along the plane of extension and the inlet opening opens into the inlet chamber at a second location different from the first location when viewed along the plane of extension.

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.

The present disclosure provides a system for oxygenating blood. The system may include an implantable blood pump that may draw a supply of blood from the circulatory system of a mammalian subject, such as a human being. The blood pump may provide the supply of blood to an adaptor, where the supply of blood may be supplied to either or both of a first branch or second branch. The first branch may lead to an external blood oxygenator. The oxygenator may oxygenate the blood, and the blood may be returned to the circulatory system of the mammalian subject. The second branch may bypass the oxygenator and may connect to the circulatory system of the mammalian subject. In this regard, while the blood is supplied to the second branch, the oxygenator may be disconnected and blood may be prevented from entering the first branch.

Provided is a pressure gauge capable of being effectively used for internal pressure measurement of a balloon catheter and capable of providing easy monitoring of a pressure value even when measuring internal pressure of an extracorporeal circulation circuit. The pressure gauge measures internal pressure of a balloon catheter used for treatment and diagnosis or pressure of a body lumen of a living body and includes a coil-shaped tube 2 to elastically deform. One end of the tube 2 is set as an open fixed end and the other end is set as a sealed free end and pressure introduced from the open fixed end can be measured based on a displacement position of the tube 2 due to the pressure.

Microplegia systems describe herein use syringe pumps that are controlled in a coordinated fashion to deliver cardioplegia medications during an open-heart surgery at the prescribed dosages and/or rates. The microplegia systems link the delivery rate of the syringe pumps with the delivery rate of the cardioplegia blood flow rate. A perfusionist can enter prescribed drug concentrations, desired ratios between drug and blood, and the expected dose for each phase of the myocardial protection scheme that will take place during the open-heart surgery. Additionally, or alternatively, the syringe pump systems described herein can also be used to deliver other non-cardioplegia types of therapeutic substances

The present invention relates to systems and devices to treat and/or prevent inflammatory conditions within a subject and to related methods. More particularly, the invention relates to systems, devices, and related methods that sequester leukocytes and/or platelets and then inhibit their inflammatory action.

An extracorporeal blood circulator includes a control unit and a speed manipulation section. A rotation display section displays a lower limit rotation setting value of a pump motor in accordance with a command of the control unit. The lower limit rotation speed setting value is a minimum rotation speed for preventing backflow of blood inside a circulation circuit A manually adjusted speed setting request from the manipulation section controls the pump speed, except that the controller enforces the lower limit speed setting unless receiving confirmation from a manipulator.

Devices can be used to detect a level of a fluid in a medical fluid reservoir. Methods for controlling the flow rate of a medical pump, and/or the occlusion amount of a medical fluid tube, that are based on the detected level of fluid in the medical reservoir can be used in a clinical setting.

The example systems, apparatus and methods use a local perfusion extracorporeal circuit (LPEC) for perfusing a local target region of a body, with a systemic perfusion extracorporeal circuit (SPEC) coupled to the core region of the vasculature using a peripheral placed loop to the body, and a control procedure to cause the local target region of the body to be at a specified pattern of temperature values that are different than the temperature of the core of the body.
