Abstract
A minimally invasive system comprises an elongate medical instrument including a lumen; an elongate, flexible stylet removably receivable within the lumen; a sensor system coupled to the stylet, the sensor system configured to detect characteristics of at least a portion of the elongate medical instrument; and a processor. The processor comprises an error detection module configured to receive the detected characteristics from the sensor system; compare the detected characteristics with expected characteristics of at least the portion of the elongate medical instrument; and notify a user of a deviation between the detected characteristics and the expected characteristics. The processor further comprises a path planning module configured to intraoperatively generate, based on a shape of at least the portion of the elongate medical instrument detected by the sensor system, a target trajectory for continuing advancement of the elongate medical instrument within a patient anatomy.
