Abstract
Devices and methods for vascular navigation, assessment and/or diagnosis are described which determine the location of the tip of a vascular catheter using the introduction of a medium with a measurable parameter (e.g., temperature, light reflection, sound reflection, etc.) and sensing and measuring the measurable parameter as the catheter is advanced. Measurements of the parameter are tracked over time, recorded and analyzed. The value of the parameter and/or the shape of the parameter value vs. time curve may be used in the analysis. For example, curve amplitude, variability, standard deviation, slope, etc. may be used in the analysis of catheter location.
Claims20
A location detection system, comprising:
- an elongate body with a lumen;
- a first sensor positioned along the elongate body at or in proximity to the distal end of the elongate body;
- one or more openings located in proximity to the distal end and near the first sensor, wherein the first sensor is configured to measure at least one parameter of a mixture of a first fluid and a second fluid after the first fluid is emitted from the one or more openings and into the second fluid;
- a controller in communication with the first sensor, wherein the controller is configured to receive a signal indicative of the at least one parameter of the mixture and is further configured to obtain a position of the first sensor within a body of a subject based upon the signal;
- and
- an ECG electrode incorporated into the elongate body and in communication with the controller.
