  • Patent number: 9750489
    Abstract: An internal tissue puncture closure method and apparatus. The method and apparatus provide a folded sealing plug that provides more surface area than conventional plugs to more fully cover and seal an external situs of an internal tissue puncture. The folded sealing plug may have a weave pattern that tends to cause the sealing plug to corkscrew into the internal tissue puncture as it is compressed toward an anchor placed inside of the tissue puncture.

  • Patent number: 9138219
    Abstract: Embodiments relate to implantable devices for the treatment of syndesmosis injuries. Embodiments include a first anchor attachable to a first bone, the first anchor being coupled to a flexible component, the flexible component in turn being coupled to a base component. The base component may be rigid, and may be externally threaded for engaging with a second anchor. Position of the second anchor may be adjusted by rotating the second anchor with respect to the base component, thereby adjusting relative position of the two bones. An assembly may be created in which an outer tube contains the flexible component and the base component inside the outer tube, and at its distal end the outer tube may engage the first anchor so as to allow transmission of torque. The outer tube may be withdrawn proximally after implantation of the first anchor. The bones may be a tibia and a fibula.

  • Patent number: 8915932
    Abstract: The present invention describes apparatus and methods for tying a filament across subcutaneous punctures. According to some embodiments, the apparatus and methods provide pre-tied knots that are inserted into a bodily lumen. Needles flanking the subcutaneous puncture are inserted into the lumen and grab the pre-tied knots. The pre-tied knots are pulled through tiny holes flanking the subcutaneous puncture by the needles, leaving an internal length of the filament across the subcutaneous puncture. The filament is then externally tied, closing the subcutaneous puncture.

  • Patent number: 8486062
    Abstract: A curved ablation catheter imparts ablative energy to target tissue, for example, along a trabecular slope, e.g., in the right atrium along the isthmus between the ostium of the inferior vena cava and the tricuspid valve. The catheter is formed with a preset curvature that, when deployed, both translates linearly and increases in radius to aid in the formation of spot or continuous linear lesions. A method of treating atrial flutter employs the curved ablation catheter.
