Abstract: Some aspects of this disclosure generally are related to improving the robustness of a flexible circuit structure, for example, by providing fault-tolerant electrical pathways for flow of electric current through the flexible circuit structure. In some embodiments, such fault tolerance is enhanced by way of a conductive mesh provided between an adjacent pair of resistive elements. Some aspects are related to improved voltage, current, or voltage and current measurement associated with various pairs of adjacent resistive elements at least when the various pairs have differing distances between them.

Abstract: A catheter device system may include a plurality of transducers positionable in a bodily cavity defined by at least a tissue wall, each transducer configured to sense a degree of contact between the transducer and the tissue wall. A data processing device system may be configured by a program to receive a plurality of degree-of-contact signals respectively from the plurality of transducers, the signals respectively indicating a degree of contact between the transducer and the tissue wall; identify a particular transducer as belonging to a first transducer set and as exhibiting an improper contact arrangement with the tissue wall as compared to a predetermined tissue-contact state, based at least on an interaction with data associated with at least one of the received degree-of-contact signals; and, consequently, provide an indication of a contact-improvement procedure to facilitate an improved contact arrangement between the particular transducer and the tissue wall.

Abstract: In some embodiments, a plurality of transducers of a transducer-based device may be selected for activation. A first pair of subsets of the selected transducers may be identified for initial activation, each subset of the first pair being activated with a different phase angle range than the other. No transducer in one subset is sufficiently close to a transducer in the other subset to cause a confluence of ablated tissue regions therebetween. The first pair of subsets may be activated simultaneously or concurrently. Upon activation or a conclusion thereof of the pair of subsets of the selected transducers, one or more subsequent pairs of subsets of the selected transducers may be activated iteratively on a pair-by-pair basis, until all of the selected transducers have achieved desired activation results, according to some embodiments. Each subsequent pair may include the same or similar characteristics as the first pair.

Abstract: Transducer-based systems can 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. 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. 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 representation may be displayed including at least a plurality of transducer graphical elements, each transducer graphical element of the plurality of transducer graphical elements representative of a respective transducer of a plurality of transducers of a transducer-based device. A set of user input may be received including an instruction set to reposition a first transducer graphical element in a state in which the first transducer graphical element is located at a first location in the graphical representation and a second transducer graphical element is located at a second location in the graphical representation, the second location closer to a predetermined location in the graphical representation than the first location. In response to conclusion of receipt of the set of user input, the first transducer graphical element may be repositioned from the first location in the graphical representation to the predetermined location in the graphical representation.

Abstract: Medical systems are disclosed which may include an elongate shaft member and a plurality of steering lines operable to cause bending of the elongate shaft member via movement of at least one of the steering lines. A respective second end portion of a first proximal steering line may terminate at a first proximal termination portion of the elongate shaft member, and a respective second end portion of the first distal steering line may terminate at a first distal termination portion of the elongate shaft member. The elongate shaft member may be formed of materials of different hardness to provide preferential bending in desired directions.

Abstract: A device for closing at least one opening leading to an anatomical cavity is delivered via a catheter positioned in a first opening leading to the anatomical cavity. An orientation control unit is positioned within the anatomical cavity. The orientation control unit defines an orientation of a portion of a tissue surface within the anatomical cavity that is skewed with respect to the first opening and orients a closure member of the device with the tissue surface. An occluding member and a constricting unit of the device are positioned within the anatomical cavity with the occluding member blocking a portion of an opening that is constricted by the constricting unit. An intermediate member of the device is positioned within the anatomical cavity and a closure unit employing at least one piercing element pierces through the intermediate member into a tissue wall surrounding the anatomical cavity.
