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.

Abstract: A system and method for determining a pH level of blood in a vessel of a patient including a flexible elongated member configured and dimensioned for insertion in the vessel of the patient, a sensor positioned at the distal portion of the elongated member, and a connector connecting the elongated member to an indicator. The sensor measures the pH level of blood downstream of the blood clot. A system and method are also provided for determining a density of a blood clot in a vessel of a patient for subsequent selection of a treatment method. The system includes a sensor positioned at the distal portion of the elongated member, and a connector connecting the elongated member to an indicator, wherein the sensor determines the density of the blood clot and the indicator provides an indication of the density of the clot.

Abstract: A medical system and method for density assessment utilizing ultrasound. The system includes a guidewire configured and dimensioned for insertion in the vessel of the patient, a sensor positioned at the distal portion of the elongated member and a connector connecting the elongated member to an indicator, the sensor determining the density and the indicator providing an indication of the determined density.

Abstract: A system for controlling reperfusion in a blood vessel of a patient including a flexible elongated member configured and dimensioned for insertion in the vessel of the patient, the elongated member having a proximal portion and a distal portion, the elongated member configured for insertion so the distal portion extends distal of a clot in the blood vessel. A sensor is positioned at the distal portion of the elongated member for positioning distal of the blood clot, the sensor measuring a parameter of blood downstream of the clot. An indicator communicates with the sensor, the indicator indicating a measured parameter for insertion of an instrument for controlling blood flow.
