Patent number: 8133184Abstract: A method for performing an in-vivo calibration of a blood pressure sensor that is associated with a balloon of an in-vivo balloon system, the sensor and balloon being associated such that the sensor is in-vivo when the balloon is in-vivo. The balloon is inflated so that a gas pressure in the balloon system is indicative of a patient's blood pressure. The patient's blood pressure is monitored through two channels, the gas pressure and the sensor. The blood pressure measurements obtained by monitoring the gas pressure are used as reference, or “true,” blood pressure measurements to determine a mathematical relationship between blood pressure measurements obtained through the sensor and the reference blood pressure measurements. In this manner, future blood pressure measurements obtained through the sensor can be modified according to the mathematical relationship to generate calibrated blood pressure measurements.Type: GrantFiled: July 8, 2010Date of Patent: March 13, 2012Assignee: Datascope Investment Corp.Inventors: Jonathan Williams, Shrenik Daftary, Robert Hamilton

Patent number: 8038623Abstract: A method for performing an in-vivo calibration of a blood pressure sensor that is associated with an in-vivo balloon system. The method involves monitoring a patient's blood pressure by observing the system gas pressure while at the same time monitoring the patient's blood pressure through the sensor. The blood pressure measurements obtained by monitoring the system gas pressure are used as reference, or “true,” blood pressure measurements, and an “offset” is determined between the reference blood pressure measurements and the blood pressure measurements obtained through the sensor. The offset can be stored in a memory, which may also store sensor sensitivity data. The offset and/or sensitivity data may be used to adjust future measurements obtained from the sensor, thereby generating calibrated sensor measurements.Type: GrantFiled: March 25, 2010Date of Patent: October 18, 2011Assignee: Datascope Investment Corp.Inventors: Jonathan Williams, Shrenik Daftary, Boris Leschinsky
