  • Publication number: 20230211130
    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.

  • Publication number: 20220168488
    Abstract: A double-lumen percutaneous femoral cannula for extracorporeal membrane oxygenation (ECMO) is an apparatus that is used to perform an ECMO procedure in non-ideal conditions. The apparatus may include at least one first cannula and at least one second cannula of different sizes that are arranged to form a single structure. By providing a single structure instead of several separate components, the apparatus makes the insertion of the apparatus easier and reduces the risk of the apparatus dislodging while the patient is being transported. The at least one first cannula and the at least one second cannula are preferably elongated tubular structures designed to prevent the recirculation of oxygenated blood. The at least one first cannula is designed to enable the aspiration of deoxygenated blood, while the at least one second cannula is designed to enable the pumping of oxygenated blood back into the body.

  • Patent number: 9642642
    Abstract: A guide tip introducer is provided as a compatible attachment for a wide range endoscopic staplers of different makes and models. The guide tip introducer mounts to the anvil of an existing endoscopic stapler in order to facilitate the positioning of the stapler beneath a target structure, reducing the amount tissue needing to be dissected. The guide tip introducer is easy to attach and remove from the anvil tip through its particular shape and through the use of a magnetic attachment strip. The guide tip introducer is constructed from smooth semi-rigid material enabling guidance of the endoscopic stapler while minimizing damage around target structures. The guide tip introducer is fashioned using commonly available material found in most standard operating rooms.
