  • Patent number: 11497898
    Abstract: Catheters with weeping balloons can be used for various medical purposes. For example, in some embodiments provided herein weeping balloons are used for catheter visualization devices. In some embodiments, weeping balloons are used to deliver therapeutic agents. Weeping balloons can include openings of a selected size and shape through which a fluid gradually flows or “weeps.” The design of the openings can affect performance characteristics such as, but not limited to, fluid flow rate, tear resistance, and mitigation of counter-flow.

  • Patent number: 11464947
    Abstract: An aortic perfusion catheter is an apparatus that is used during surgery for acute ascending aortic dissection to reduce postoperative injuries from profound hypothermia, ischemia, and reperfusion. The apparatus may include at least one main cannula, an inflation cannula, a drainage cannula, and a balloon tamponade. The at least one main cannula helps maintain blood perfusion to the body during the procedure to reduce postoperative injuries. The inflation cannula enables the selective inflation and deflation of the balloon tamponade to facilitate the insertion and removal of the balloon tamponade along with the at least one main cannula within the descending thoracic aorta. The balloon tamponade prevents blood flow into the operative area to maintain the operative area clear during the procedure. The drainage cannula enables the drainage of blood that may escape the balloon tamponade as well as other bodily fluids.

  • Patent number: 11364333
    Abstract: Disclosed herein is a bidirectional intravascular cannula, or catheter, that is configured to provide and return blood in a patient bidirectionally. The bidirectional intravascular cannula is configured to reduce or obviate the need for a second cannula, such as currently available unidirectional cannulae, to be placed in a second or opposite direction of flow. Users would include cardiac surgeons, intensivists, vascular surgeons, ER doctors, IR doctors and cardiologist who use peripheral cannulation for ECLS or cardiopulmonary bypass. The cannula allows continued flow to a patient's limb even with the cannula proximally in the vessel. The cannula further allows larger size cannula to be placed without the need for additional distal catheter placement.
