  • Patent number: 10869655
    Abstract: Systems and methods for the treatment of perforator veins for venous insufficiency are described. The systems can include a catheter assembly comprising a proximal hub, a spin lock on the proximal hub, a elongate body overmolded to the proximal hub, and a distal end, the catheter, the elongate body configured to be placed within a perforator vein; an extension tubing having a proximal female hub, a distal male hub, and an elongate body therebetween, the distal male hub having a spin lock thereon, the distal male hub configured to be attached to the proximal hub of the catheter assembly; a syringe filled with a volume of media including cyanoacrylate; and an injector configured to automatically dispense a bolus of the media sufficient to coapt the perforator vein from the syringe upon actuation of a control on the injector. Methods are also disclosed.

  • Publication number: 20190099171
    Abstract: Methods and devices for providing improved ultrasound visibility of medical devices intended for intravascular use are described. The inclusion of gas/solid boundary regions within a medical devices improves the resolution of the device under ultrasound visualization. Gas/solid boundary regions may be provided through the use of embedded gas-filled microlumens, microwells, or enclosed pockets within the medical device.
