  • Publication number: 20210346001
    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: 11134933
    Abstract: A collapsible medical device and associated methods of occluding an abnormal opening in, for example, a body organ, wherein the medical device is shaped from plural layers of a heat-treatable metal fabric. Each of the fabric layers is formed from a plurality of metal strands and the assembly is heat-treated within a mold in order to substantially set a desired shape of the device. By incorporating plural layers in the thus-formed medical device, the ability of the device to rapidly occlude an abnormal opening in a body organ is significantly improved.

  • Publication number: 20210275183
    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: 9765689
    Abstract: An internal combustion engine includes a standard connecting rod as well as a gear rack. The connecting rod can be a standard connecting rod that reciprocates with the piston and that drives a rotatable crank mechanism to convert the reciprocating motion of the piston into rotation of the crankshaft. The gear rack is also connected to and reciprocates with the piston. The gear rack is engaged with a gear that is mounted on the crankshaft. A one-way drive mechanism is provided between the gear and the crankshaft that transmits torque (i.e. rotary force) to the crankshaft only during the power stroke of the piston.
