EXTRACORPOREAL CIRCULATION MANAGEMENT DEVICE AND EXTRACORPOREAL CIRCULATION DEVICE HAVING IT
An extracorporeal blood circulation management device having an oxygenator accurately determines oxygen consumption by the target person and oxygen delivery by the oxygenator. Oxygenation-related parameter values in the blood are determined at regular intervals. An in-body passing time (a cycle time for a particular volume of blood to pass from input sensors to output sensors) is determined. Parameter values separated by the in-body passing time are selected as comparison targets to evaluate oxygenation consumption of the target person. An oxygenator unit passing time is determined. Parameter values separated by the oxygenator unit passing time are selected as comparison targets to evaluate oxygenation delivery of the oxygenation unit.

Device and Method for Attenuation of CO2 in Circulating Blood
Systems and methods for the removal of carbon dioxide from circulating blood via the use of microbubbles within a body cavity, optionally including the simultaneous provision of oxygen to the circulatory system. Through placement of microbubbles within a body cavity and the use of a carbon dioxide scavenging catheter, carbon dioxide and/or oxygen exchange may occur. Overall improvement in extending survival rate time during emergency situations caused by pulmonary or similar ventilation restricting injury and/or failure may be achieved.

NEUROVASCULAR CATHETER EXTENSION SEGMENT
A neurovascular catheter extension segment is provided, such as for distal neurovascular access or aspiration. The neurovascular catheter extension segment includes 1) an elongate flexible control wire having a proximal end and a distal end and 2) a tubular extension segment having a side wall defining a central lumen carried by the distal end of the control wire. The side wall of the tubular extension segment includes a tubular inner liner, a tie layer separated from the lumen by the inner liner, a helical coil surrounding the tie layer, and an outer jacket surrounding the helical coil. The extension segment may be introduced into the proximal end of a neurovascular catheter and advanced distally to extend beyond the catheter and thereby extend the reach of the catheter.

Method and System for Controlled Hyperthermia
An improved system and methods for treatment of cancer and other diseases including complications from late-stage viral infections by inducing hyperthermia in a patient relying on withdrawing blood from the patient and returning the withdrawn blood to the patient to establish an extracorporeal flow circuit. Blood is heated by passing through the extracorporeal circuit at a controlled rate until a target body core temperature in is achieved. Usually, the blood will be subjected to a continuously re-circulating dialysis to balance electrolytes. Additionally, the blood will be subjected to a continuously recirculating regeneration through a carbon sorbent column where toxins and contaminants are removed. The blood temperature is maintained at the target blood temperature for a treatment period, and the blood is cooled after the treatment period has been completed. The method can also be effective in treating rheumatoid arthritis, scleroderma, hepatitis, sepsis, the Epstein-Barr virus, and patients with life threatening complications from other viruses, including the COVID-19 virus. A method for removing viruses from the blood supply in an external circuit is also presented. An adjunct of the present invention is enhanced production of stem cells as a result of employing the HEATT process. A further adjunct is production of transgenic swine with extant viral infections.
