  • Publication number: 20190239948
    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.

  • Publication number: 20190168300
    Abstract: A metal object is created, layer by layer, by extruding a metallic water-based paste containing a low amount of binder, using a positive displacement pump located near the nozzle. A support structure is created by a second pump using a low strength water-based paste. The object is partially dried as it is printed, followed by full drying and sintering.

  • Publication number: 20190126509
    Abstract: A 3D printer creates a ceramic casting shell of high accuracy. Casting molten metal into this shell creates an accurate metal object. The ceramic shell is formed from a paste made from a low hardness ceramic, dried by freeze drying. To overcome the shear thinning behaviour of ceramic pastes a positive displacement pump is in close proximity to the nozzle.

  • Publication number: 20190090928
    Abstract: The invention may be applied to selectively heat a diseased area in the lung while minimizing heating to the healthy area and surrounding tissue. This can be done by exposing the lung to an electromagnetic field causing dielectric or eddy current heating. The invention is particularly useful for treating emphysema as the diseased areas in emphysema patients have reduced blood flow. The diseased area will heat up rapidly while the healthy tissue will be cooled by the blood flow. This is particularly effective for treating emphysema because of the low mass of the lungs and the high blood flow. To avoid heating of surrounding organs the direction of the electromagnetic energy may be switched in a way it always passes through lungs but only intermittently passes through adjacent organs.

  • Publication number: 20190008641
    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.

  • Patent number: 10002680
    Abstract: An apparatus for generating a pressure wave in a liquid medium is disclosed. The apparatus includes a plurality of pressure wave generators having respective moveable pistons, the pistons having respective control rods connected thereto. The apparatus also includes a plurality of transducers coupled to the liquid medium and means for causing the pistons of respective ones of the plurality of the pressure wave generators to be accelerated toward respective ones of the plurality of transducers. The apparatus further includes means for causing restraining forces to be applied to respective control rods to cause respective pistons to impact respective transducers at respective desired times and with respective desired amounts of kinetic energy such that the respective desired amounts of kinetic energy are converted into a pressure wave in the liquid medium.

  • Patent number: 9991014
    Abstract: The preferred embodiment of the disclosed invention comprises rotary actuators that move one or more x-ray attenuating plates in the x-y plane (ie. image plane). These x-ray attenuating plates attenuate the x-ray beam with thin metal sheets or plates that contain one or more apertures, which fully exposes the desired region of interest (ROI) while filtering the rest of the image, reducing the radiation exposure for the procedure. The devices will typically have a selection of many attenuation profiles. A small aperture or low attenuation profile region will result in a higher total exposure reduction and a large aperture or large attenuation profile will result in a smaller exposure reduction. The x-ray attenuating plate can be rotated to select an attenuation profile using a detent wheel.

  • Publication number: 20180036074
    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).
