Systems, methods, and devices allow percutaneous mapping, orientation and/or ablation in bodily cavities or lumens. Such may include a structure that is percutaneously positionable in a cavity, such as an intra-cardiac cavity of a heart. Transducers carried by the structure are responsive to blood flow. For example, the transducers may sense temperature, temperature being related to convective cooling caused by blood flow. A controller discerns positional information or location, based on signals from the transducers. For example, blood flow may be greater and/or faster proximate a port in cardiac tissue than proximate tissue spaced from the port. Position information may allow precise ablation of selected tissue, for example tissue surround a port in the intra-cardiac cavity.

A system is provided to treat sleep apnea, with a method of use. The system includes a handpiece which includes at least one penetrating electrode configured to penetrate tissue and one or more temperature sensors. A processor is coupled with the one or more temperature sensors and the at least one penetrating electrode, and a memory is configured to store instructions executable by the processor. The instructions, when executed, are operable to emit, by the at least one penetrating electrode, RF energy from the electrodes to heat a region of a base of a tongue until a target energy is delivered to the region. The instructions are also operable to measure, by the one or more temperature sensors, the temperature of the region.
