    Abstract: Transducer-based systems and methods may be configured to display a graphical representation of a transducer-based device, the graphical representation including graphical elements corresponding to transducers of the transducer-based device, and also including between graphical elements respectively associated with a set of the transducers and respectively associated with a region of space between the transducers of the transducer-based device. Selection of graphical elements and/or between graphical elements can cause activation of the set of transducers associated with the selected elements. Transducer activation characteristics, such as initiation time, activation duration, activation sequence, and energy delivery characteristics, can vary based on numerous factors. Visual characteristics of graphical elements and between graphical elements can change based on an activation-status of the corresponding transducers. Activation requests for a set of transducers can be denied if it is determined that a transducer in the set of transducers is unacceptable for activation.

    Abstract: 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.

    Abstract: A graphical path, which may illustrate a proposed transducer-activation path, may be defined in accordance with first user input, which places a first user input element in an activated state, motion-based user input, and second user input, which places the first user input element in a deactivated state. The graphical path may be displayed as including transducer graphical elements, between-transducer graphical elements, or both, and may be displayed among at least one graphical representation of intra-cardiac information. Activation of transducers corresponding to transducer graphical elements included in the graphical path may be initiated during or after completion of the definition of the graphical path. Such activation may include the transmission of energy sufficient for tissue ablation along an ablation path corresponding to the graphical path.
