  • Systems and methods for aspirating from a body lumen
    Patent number: 11857208
    Abstract: An aspiration device can be used to aspirate an obstruction from a blood vessel. The aspiration device is configured to allow controlled one-handed aspiration yet maintain a syringe plunger feel of vacuum. The aspiration device also allows one-handed injection to empty the device when needed. Furthermore, mechanisms enable one-handed locking of a plunger position of the device to maintain vacuum when the user releases the device.
    Type: Grant

  • Biliary stents and methods
    Patent number: 11504221
    Abstract: A tissue lumen stent is provided with a body having an elongated tubular configuration and a foreshortened configuration. In the foreshortened configuration, downstream and upstream ends of the body expand radially into downstream and upstream flange structures, leaving a generally cylindrical saddle region therebetween. In some embodiments, the flange structures are non-symmetrical with respect to one another. Systems and methods of using the stents are also disclosed.

  • Methods and systems for establishing retrograde carotid arterial blood flow
    Patent number: 11433226
    Abstract: Devices and methods establish and facilitate retrograde or reverse flow blood circulation in the region of the carotid artery bifurcation in order to limit or prevent the release of emboli into the cerebral vasculature such as into the internal carotid artery. The methods are particularly useful for interventional procedures performed through a transcarotid approach or transfemoral into the common carotid artery.
