Patent ID: 8906011

Claim:
A medical system, comprising: a medical device including a frame positionable in at least a portion of a bodily organ, the frame including a plurality of transducer electrodes to sense at least in part a physical interior surface of a tissue wall, the physical interior surface interrupted by one or more ports in fluid communication with the bodily organ, each of the transducer electrodes responsive to at least one characteristic indicative of whether a fluid or non-fluid tissue is present and not indicative of a flow of the fluid in the bodily organ; a computing system coupled to the medical device and including at least one processor and at least one memory that stores instructions, the computing system configured to determine a position of the medical device in the bodily organ at least by executing a mapping process to map the bodily organ, the mapping process including locating positions of the one or more ports at least by computationally discriminating between the fluid and the non-fluid tissue based at least in part on the at least one characteristic sensed by the transducer electrodes; and at least one display coupled to the computing system and configured to display output from the mapping process.
