  • Patent number: 11660426
    Abstract: The disclosure relates to devices and methods for the treatment of edema that uses an impeller with a balloon that may be mounted on the impeller housing. The invention provides devices and methods for treatment of edema that use an indwelling catheter with an impeller to lower pressure at an outlet of a lymphatic duct and a balloon on the impeller to guide and to restrict blood flow. The balloon restricts return flow from the jugular and guides that flow into the impeller cage. By funneling the flow into the impeller cage, a rate of flow down the vessel may be increased, resulting in a lateral pressure decrease effecting the lymphatic outlet. Because the lymphatic outlet is subject to a pressure decrease, fluids in the lymphatic system drain to the outlet and into the circulatory system.

  • Patent number: 11628283
    Abstract: The invention refers to endovascular catheters and methods useful to endovascular surgery. In particular, it refers to support catheters with balloons that are used for the placement or the forwarding of the guidewire through demanding tortuosity and important vascular stenoses in cases where the guidewire needs the best possible backup support of the catheter. This is achieved with the development of an endovascular support catheter with a mobile balloon, which has the ability to move along the body of the catheter, at its distal part. The movement of the balloon is achieved with the use of two mobile external rings, one inner wire circuit, and one control handle which is found at the proximal end of the device. The mobile balloon allows the catheter to move inside the vessel even when it is inflated and basically anchored within the vessel.

  • Patent number: RE49557
    Abstract: Apparatus and methods for an endovascular catheter that can be inserted within tortuous body anatomies and then selectively stiffened and fixed in place. In a particular embodiment, this stiffness is reversible. The stiffness or a comparable mechanical characteristic of the catheter assembly may be adjusted to a relatively low value during insertion (so that it easily navigates a guide wire or the like), and then subsequently adjusted to a relatively high value in situ to keep the catheter assembly substantially fixed in place (i.e., during delivery of an interventional device).
