A catheter for percutaneous cardiopulmonary support has a lumen through which blood flows to a living body. The catheter comprises a catheter tube including a tubular reinforcing body including a plurality of wires braided into a mesh shape and a resin layer provided so as to cover the reinforcing body. A plurality of side holes are formed at a distal end of the catheter tube to communicate the lumen with the outside of the catheter tube. The side holes allow the blood flowing through the lumen to flow out in a direction intersecting an axial direction of the catheter tube when the catheter tube is indwelled. The plurality of side holes preferably may be spirally arranged in a circumferential direction of the tube.

The availability of a heart-lung machine in a box provides an opportunity for saving lives in emergency situations arising outside a hospital and for more cost effective care in hospital settings.

The present invention provides a bi-directional perfusion cannula for use in peripheral veno-arterial extracorporeal membrane oxygenation of a patient, the cannula comprising a cannula main body having a primary lumen, the primary lumen leading to a distal end of the cannula main body for providing retrograde blood perfusion, characterized in that the main body further comprises a passage for passing a second cannula therethrough, the passage being oriented such that when a second cannula is inserted into the passage the second cannula is arranged for providing anterograde blood perfusion.

This document describes medical systems for monitoring parameters of a patient during a medical procedure. A user, such as a practitioner, can provide input of parameter settings for ranges of patient parameters and semi-autonomous adjustments to the parameters. The semi-autonomous adjustments can be executed at a later time during the procedure, based on sensed real-time changes to the patient parameters. A computer system can monitor, in real-time, the patient parameters and generate GUI displays to be presented at the user's device. The GUI displays can output sensed real-time changes in the patient parameters, controls to adjust ranges for each of the parameters, and controls to perform semi-autonomous adjustments. The computer system can also generate projected trends for the real-time parameters, which can be used by the user to adjust patient parameters during the procedure. User selection of semi-autonomous adjustments can be executed by the computer system at a heart/lung machine.

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.

A cardiopulmonary bypass system is described that includes a cardiopulmonary bypass machine having a console, the console has a base and a frame connected to the base. The system further comprises a plurality of peripheral modules operatively connectable to the cardiopulmonary bypass machine via one or more cables. The system further comprises a cable chase having a first end and a second end, and a housing that extends at least partially between the first end and second end to at least partially enclose a channel for receiving one or more cables or conduits connected to one or more of the peripheral modules.

A device comprising a bag made of flexible material and defining a containment volume of a liquid; at least a first duct associated with the bag and provided with a first transit port placed inside the containment volume for the introduction of an operating liquid inside it; at least a second duct associated with the bag and provided with a second transit port placed inside the containment volume for the outflow of the operating liquid to the outside; at least a third duct associated with the bag and provided with a third transit port placed inside the containment volume for the reintroduction of the operating liquid inside it; and at least a fourth duct associated with the bag and provided with a fourth transit port placed inside the containment volume for the outflow to the outside of the air present in the containment volume itself and in the operating liquid.

The present invention generally relates to a process suitable for extracorporeal lung support. The process comprises contacting blood with a dialysis liquid separated by a semipermeable membrane. Oxygen is introduced into blood and/or into the dialysis liquid prior to contacting blood and dialysis liquid being separated by the semipermeable membrane. The process is versatile and allows for blood oxygenation as well as removal of at least one undesired substance occurring in the blood, selected from carbon dioxide, bicarbonate and hydrogen cations, from blood. Thereby, the present invention takes advantage of the Haldane effect in the extracorporeal contacting step. The undesired substance can be efficiently transported across a semipermeable membrane to the dialysis liquid. In contrast to extracorporeal carbon dioxide removal methods of the prior art (ECCCbR), the present invention employs a versatile dialysis liquid that allows to adjust the pH and buffering capacity of the dialysis liquid, to add fluids to the dialysis liquid and/or to the blood and to remove substances from the blood in the extracorporeal circuit, depending on the conditions and needs. The present invention also provides regeneration and recycling of the dialysis liquid, and thus for its repeated use. The present invention is suitable for treating human or animal subjects suffering from lung failure or lung disorders.

This document describes devices used during surgical procedures for the treatment of heart conditions. For example, this document describes technology to monitor the operations of a heart-lung machine and then shows associated read outs on a head-worn display in order to provide an augmented-reality presentation. For example, various sensors on and around a heart-lung machine, patient, and/or extracorporeal circuit can monitor the operations of the procedure using the heart-lung machine.

The present invention relates to a catheter that minimizes or eliminates the recirculation of oxygenated blood. The catheter of the present invention can be used to drain blood from multiple points in the patient, namely the superior vena cava, right atrium, and the right ventricle, while returning blood to the patient's pulmonary artery. Further, the catheter of the present invention is less likely to be moved or dislodged than catheters currently available in the art, thus making the catheter particularly useful for portable lung assist devices. The present invention also relates to methods for inserting the catheter into the patient and using the catheter with a lung assist device.
