  • Embolic protection device
    Patent number: 11166804
    Abstract: An embolic protection device includes an expandable and contractible filter that can be supported by one or more struts. The struts can be connected to the filter or interwoven into the filter, so as to assist in the expansion and contraction of the filter. In one embodiment, the proximal ends of the struts connect to a joint that is fixed in position relative to a delivery wire, while the distal end of the filter connect to a joint that slides relative to the delivery wire.

  • Occlusion Systems
    Publication number: 20210330333
    Abstract: An occlusion device with particular utility in occlusion of left atrial appendages is described. The occlusion device utilizes an inflatable balloon comprising a proximal portion to inflate with an inflation fluid delivered by an outer catheter body and conform to a shape of the left atrial appendage and a distal portion to fill with an adhesive delivered by an inner catheter body. The distal portion of the inflatable balloon sticks to the tissue wall of the left atrial appendage. The outer catheter body is configured to position the inner catheter body inside the outer catheter body.

  • Method for producing a living body tissue three-dimensional model
    Patent number: 10926472
    Abstract: An internal tissue including a lesion region in the human body is modeled as a three-dimensional model. By reconstructing thickness or flexibility of a lumen wall portion including the lesion region and making it possible to confirm a motion of the lumen wall or a flow of fluid in the inside of the lumen wall, a state of the lesion region in the lumen can be confirmed clearly by visual inspection or the like. As a result, the diagnosis in the lumen can be made easier.
