Abstract

Exemplary systems, devices, and methods use a local perfusion extracorporeal circuit (LPEC) to perfuse a localized target area of ​​the body, wherein the systemic perfusion extracorporeal circuit (SPEC) is coupled to a core region of the body's vasculature using a peripherally placed loop, and controls The procedure subjects the localized target area of ​​the body to a specific pattern of temperature values ​​that differ from the temperature of the body's core.

Description

Background technique [0001] Although hypothermia (low core body temperature) can be detrimental in many circumstances, it has been found to offer some therapeutic advantages. Therefore, it may be intentionally induced as therapeutic hypothermia. For example, periods of cardiac arrest in myocardial infarction and cardiac surgery settings can produce brain damage or other neurological damage. In the medical community, hypothermia is considered a recognized neuroprotective agent during cardiovascular surgery. Patients may be maintained in a state of induced hypothermia during cardiovascular surgery. Hypothermia is also sometimes induced as a neuroprotective agent during neurosurgery. Therapeutic hypothermia can be advantageously used to prevent or reduce tissue damaging effects from ischemic and other injuries. For example, tissue damage accompanying ischemic injury can begin at the onset of ischemia and continue through the reperfusion phase after blood flow is restored. Bo...
