Cut-to-Length Sensing Catheters and Methods Thereof

Abstract

Cut-to-length sensing catheters retain their sensing capabilities and methods thereof. For example, a sensing catheter can include a catheter tube having temperature sensors along an initial length thereof. Each temperature sensor is independently electronically addressed, thereby enabling a temperature-sensing capability of the sensing catheter to be maintained despite excising any one or more temperature sensors with a distal length of the catheter tube upon cutting the catheter tube to a working length. Such a sensing catheter can further include strain sensors respectively paired with the temperature sensors along the initial length of the catheter tube, thereby enabling correction of temperature-measurement uncertainty in any temperature sensor by way of a local strain measurement. Such a sensing catheter can further include lactate sensors respectively paired with the temperature sensors, thereby enabling enzyme activity and, thus, lactate concentration, associated with any lactate sensor to be normalized by way of at least local-temperature compensation.
