Abstract
Systems and methods for navigation and positioning a central venous catheter within a patient. The system may include a first pole and a second pole designed to generate an electric field sufficient to obtain a plurality of field measurements. The system may include a stylet inserted into a medical device. The stylet may include a magnetic assembly configured to produce a magnetic field positioned along a distal portion of the stylet, and a stylet electrode positioned distal of the magnetic assembly. The stylet electrode may be designed to function as both an interior excitation electrode and an interior detection electrode. Advancement of the medical device in the patient may include using a conductance curve generated from the plurality of field measurements to identify an obstruction or malposition in the patient.
