Claim 0:
1. A catheter navigation system comprising:
an input-output device system communicatively connected to a display device system;
a memory device system storing a program; and
a data processing device system communicatively connected to the input-output device system and the memory device system, the data processing device system configured at least by the program at least to:
receive a plurality of location signal sets, each location signal set of the plurality of location signal sets indicative of a respective location in a sequence of locations at which at least a portion of a catheter has sequentially moved to in a bodily cavity, the catheter comprising a plurality of transducers;
receive a plurality of contact signal sets from a first set of transducers of the plurality of transducers, each transducer of at least the first set of transducers configured to detect transducer-to-tissue contact, each contact signal set of the plurality of contact signal sets indicating a degree of transducer-to-tissue contact between each transducer of the first set of transducers and a tissue surface within the bodily cavity, and each contact signal set corresponding to a respective location in the sequence of locations of the at least the portion of the catheter in the bodily cavity; and
cause the display device system to progressively visually represent, in a progressively enlarging manner and based on and throughout reception of at least the plurality of location signal sets, at least a portion of an envelope, the envelope representing an interior volume of the bodily cavity, and the progressively enlarging manner increasing a space represented by the envelope,
wherein the data processing device system is configured at least by the program at least to cause the display device system to cause the visually represented at least the portion of the envelope to visually indicate, based on at least the plurality of contact signal sets, greater-contact regions of the at least the portion of the envelope associated with relatively greater transducer-to-tissue contact in accordance with a first visual characteristic set and to visually indicate lesser-contact regions of the at least of the portion of the envelope associated with relatively lesser transducer-to-tissue contact in accordance with a second visual characteristic set, the second visual characteristic set different than the first visual characteristic set.
