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 medical device system may include transducers and a structure on which the transducers are located. The structure may include at least a first portion of each elongate member of a plurality of elongate members. Each respective set of a plurality of sets of one or more of the transducers may be located on a respective one of the plurality of elongate members. The structure may be selectively moveable between a delivery configuration in which the structure is sized to be percutaneously deliverable to a bodily cavity and a deployed configuration in which the structure is sized too large to be percutaneously deliverable to the bodily cavity. The second portion of each elongate member of the plurality of elongate members may be arranged in a helical configuration or a twisted, non-helical configuration including at least 360 degrees of rotation when the structure is in the delivery configuration.

Abstract: A device positionable in a cavity of a bodily organ (e.g., a heart) may discriminate between fluid (e.g., blood) and non-fluid tissue (e.g., wall of heart) to provide information or a mapping indicative of a position and/or orientation of the device in the cavity. Discrimination may be based on flow, or some other characteristic, for example electrical permittivity or force. The device may selectively ablate portions of the non-fluid tissue based on the information or mapping. The device may detect characteristics (e.g., electrical potentials) indicative of whether ablation was successful. The device may include a plurality of transducers, intravascularly guided in an unexpanded configuration and positioned proximate the non-fluid tissue in an expanded configuration. Expansion mechanism may include helical member(s) or inflatable member(s).

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: An intra-cardiac mapping system is based on locating the ports through which blood flows in or out the heart chambers. For many procedures, such as ablation to cure atrial fibrillation, locating the pulmonary veins and the mitral valve accurately allows to perform a Maze procedure. The location of the ports and valves is based on using the convective cooling effect of the blood flow. The mapping can be performed by a catheter-deployed expandable net or a scanning catheter. The same net or catheter can also perform the ablation procedure.

Abstract: A medical device flushing apparatus may include an enclosure and at least one fluid-providing channel. The enclosure may include an interior surface defining at least part of a flushing cavity configured to receive a structure of a medical device. The at least one fluid-providing channel may interrupt the interior surface of the enclosure, the at least one fluid-providing channel configured to provide fluid to the flushing cavity. Each of the at least one fluid-providing channel may point, in a fluid-providing direction, toward an interior of the flushing cavity, each fluid-providing direction pointing away from a centroid of the flushing cavity.

Abstract: A device, kit and method may employ an implantable device (e.g., annuloplasty implant) and a tool to implant such. The implantable device is positionable in a cavity of a bodily organ (e.g., a heart) and operable to constrict a bodily orifice (e.g., a mitral valve). Tissue anchors are guided into precise position by an intravascularly deployed anchor guide frame and embedded in an annulus. Constriction of the orifice may be accomplished via a variety of structures, for example by cinching a flexible cable or anchored annuloplasty ring, the cable or ring attached to the tissue anchors. The annuloplasty ring may be delivered in a generally elongated configuration, and implanted in an anchored generally arch, arcuate or annular configuration. Such may move a posterior leaflet anteriorly and an anterior leaflet posteriorly, improving leaflet coaptation to eliminate mitral regurgitation.
