Abstract
A system and method for determining a pH level of blood in a vessel of a patient including a flexible elongated device configured and dimensioned for insertion in the vessel of the patient. The elongated device has a tubular portion, a marker band positioned distally of the tubular portion and a pH sensor positioned within the marker band to measure the pH level of blood downstream of the blood clot and an indicator to indicate the measured pH.

A system for determining a pH level of blood in a vessel of a patient, the system comprising:
- a flexible elongated device configured and dimensioned for insertion in the vessel of the patient, the elongated device having a proximal portion, a distal portion and a tubular portion having a lumen formed therein, the elongated device configured for insertion so the distal portion extends past a blood clot for positioning of the distal portion distal of the blood clot;
- a marker band, at least a portion of the marker band positioned distally of the tubular portion,
- a sensor for positioning distal of the blood clot, the sensor positioned within the marker band;
- and
- a connector operably connecting the tubular portion to an indicator, the sensor measuring the pH level of blood downstream of the blood clot to thereby determine pH of the vessel downstream of the blood clot to determine the condition of the vessel to assess subsequent treatment of the blood clot, the indicator providing an indication of the pH measured by the sensor.
A method for determining a pH level of blood downstream of a blood clot in a vessel of a patient comprising the steps of:
- providing an elongated flexible device having a radiopaque marker band and a sensor positioned within the marker band;
- inserting the flexible device through vasculature of the patient and past the blood clot to a position downstream of the blood clot in the vessel, the marker band indicating to the user the position of the sensor;
- sensing a pH level of the blood downstream of the blood clot;
- and
- indicating to the user the pH level of the blood to enable the user to determine a pH level of the vessel downstream of the blood clot for subsequent selection of a clot treatment method.
