First Claim
Patent Images
1. A system for treating a patient, comprising:
- a heat exchange catheter configured for placement in the patient to induce hypothermia in the patient when heat exchange fluid is circulated through the catheter, the heat exchange fluid not entering the bloodstream of the patient; and
a source of magnesium sulfate engageable with the patient to provide magnesium sulfate thereto through an infusion lumen of the catheter for treatment of cardiac arrest or myocardial infarction, wherein a distal portion of the catheter includes;
at least first and second elongated segments, each segment having an irregular exterior surface; and
a flexible articulating joint connecting the first and second elongated segments.
