  • Publication number: 20260013848
    Abstract: The present invention provides an improved vascular occlusion device having improved flexibility and retention of the type fabricated from braided tubular metal fabric having an expanded preset configuration and an elongated collapsed reduced diameter configuration for delivery through a catheter to a treatment site and shaped to create an occlusion of an abnormal opening in a body organ or vessel, the woven metal fabric having a memory property whereby the medical device tends to return to said expanded preset configuration when unconstrained. The device further including at least one disk portion adjacent a body cylindrical portion formed from the fabric and having a transition diameter between the disk and cylindrical portion, significantly smaller than the diameter of the disk and the diameter of the cylindrical portion.

  • Patent number: 12290263
    Abstract: Implantable occlusion devices that include one or more flanges extending from a tubular body are disclosed. The flange or flanges may assist in retention of the device within a vessel, cavity, appendage, etc. At least one flange on the occlusion device may include a concave surface proximate one end of a body. Because of the shape of the flange, e.g., its concavity, the occlusion device may resist dislocation due to e.g., the forces generated within the left atrial appendage during atrial fibrillation.

  • Patent number: 12114844
    Abstract: A collapsible medical device and methods for deploying the same are provided. The medical device includes a tubular metal fabric, which includes a plurality of braided metal strands and a proximal end and a distal end, the tubular metal fabric having a collapsed configuration for delivery and an expanded preset configuration for creating an occlusion of an opening. In the expanded preset configuration, the device has two expanded disk portions and a central portion, a first expanded disk portion and the central portion connected by a first reduced diameter portion, and a second expanded disk portion and the central portion connected by a second reduced diameter portion. Each of the first and second reduced diameter portions is smaller in diameter than both the two expanded disk portions and the central portion, and each of the first and second reduced diameter portions is recessed into the central portion.

  • Patent number: 12024135
    Abstract: The present disclosure relates to vehicle technology, and more particularly, to an unmanned vehicle and its sensor device and cleaning mechanism. The cleaning mechanism includes: a housing, a cleaning element, a driving component transmissively connected to the cleaning element and a control unit installed within a receiving cavity. The housing has a light transmissive element provided on a side surface thereof. The cleaning element is pivotable about one end thereof and mounted to the housing. The cleaning element, when pivoting, frictionally interacts with a surface of the light transmissive element that is away from the receiving cavity to clean the light transmissive element. The control unit is communicatively connected to the driving component for controlling the driving component.
