Abstract
A system for detecting and treating an anastomotic leak includes a microcatheter implanted at an anastomosis site; a source of a perfusion fluid coupled to the microcatheter and configured to dispense the perfusion fluid to the microcatheter; and an analyzer coupled to the microcatheter configured to receive an extracellular fluid from the microcatheter and to analyze the extracellular fluid to determine status of the anastomosis site.
Claims11
A system for detecting and treating an anastomotic leak, the system comprising:
- a microcatheter implanted at an anastomosis site;
- a wearable source of a perfusion fluid coupled to the microcatheter and configured to dispense the perfusion fluid to the microcatheter;
- a wearable analyzer coupled to the microcatheter configured to receive an extracellular fluid from the microcatheter and to analyze the extracellular fluid to determine status of the anastomosis site, the analyzer including:
- a lactate sensor configured to measure a concentration of lactate;
- a pyruvate sensor configured to measure a concentration of pyruvate;
- a processor configured to:
- calculate a ratio of the concentration of lactate to the concentration of pyruvate;
- and
- indicate the status of the anastomosis site based on the ratio of the concentration of lactate to the concentration of pyruvate.
