Catheter navigation systems and methods

Abstract

A catheter navigation system may be configured to produce a plurality of location signal sets indicating a three-dimensional location of a portion of a catheter in a bodily cavity and a plurality of contact signal sets indicating degrees of detected-transducer-to-tissue contact within the bodily cavity. The catheter navigation system may be configured to, based on the location signal sets and the contact signal sets progressively visually represent in a progressively enlarging manner at least a portion of an envelope representing an interior volume of the bodily cavity, concurrently with a visual representation of transducer graphical elements representing transducers that produce the location signal sets, the contact signal sets, or both, of the portion of the catheter. The visual representation of the at least the portion of the envelope, the transducer graphical elements, or both, may respectively visually represent historical and/or presently detected degrees of transducer-to-tissue contact.
