  • Publication number: 20230248939
    Abstract: A modular cannula for drainage and return of fluids from and to a body, such as the body of a patient, is adjustable to enable an operator to achieve desired flow characteristics during such fluid drainage and return procedures. The modular, dual-lumen cannula system has an outer drainage cannula and an inner return cannula that is moveable with respect to the outer drainage cannula. By enabling movement of the inner return cannula with respect to the outer drainage cannula, a distance between return outlet ports at the distal end of the return cannula and drainage ports at the distal end of the drainage cannula may be manually adjusted. Such adjustable distance allows for optimal positioning of both the drainage and return ports that are particularly adapted to an individual patient’s physiology, in turn enabling optimal fluid flow characteristics to be achieved regardless of that patient physiology.

  • Publication number: 20220313888
    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.

  • Publication number: 20190224456
    Abstract: Disclosed herein is a guidewire configured for placement of large bore catheters and cannulae inside of a patient's blood vessels without fluoroscopic guidance. The guidewire, in accordance with certain aspects of an embodiment of the invention, comprises sections of varying stiffness throughout optimally fixed length portions of the guidewire that particularly ease placement of such large bore catheters and cannulae in ECMO applications.
