20130066220 | INTRA-CARDIAC MAPPING AND ABLATING - 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. | 03-14-2013 |
20140276769 | DETECTING IMPROPER ENERGY TRANSMISSION CONFIGURATION IN MEDICAL DEVICE SYSTEM - A medical device system may be configured to detect an improper energy transmission configuration therein. The condition may be detected by way of a detection of a condition where an energy-transmitting electrode of the medical device system becomes too close to or becomes in contact with an object resulting in an inability of the electrode to properly transmit energy. For example, if the energy-transmitting electrode is a first electrode configured in its operational state to transmit energy to bodily tissue adjacent the first electrode, but the first electrode is inadvertently contacting a second electrode, such contact may cause at least some energy transmitted by the first electrode to follow an unintended path away from its intended path to the adjacent tissue. Such a condition may be detected based at least upon an analysis of information acquired from a sensing device system. | 09-18-2014 |
20150065899 | SYSTEMS AND METHODS FOR ACTIVATING TRANSDUCERS - 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. | 03-05-2015 |

Selection of graphical elements and/or between graphical elements can cause activation of the set of transducers associated with the selected elements. Selection of a plurality of graphical elements and/or between graphical elements can cause visual display of a corresponding activation path in the graphical representation. Visual characteristics of graphical elements and between graphical elements can change based on an activation-status of the corresponding transducers.
