    摘要： An extension cannula for use with a conventional ECMO return cannula is provided. The extension cannula includes a flexible conduit transitionable between a collapsed insertion state and an expanded deployed state when in communication with blood flow from an ECMO machine via the ECMO return cannula. The extension cannula may be positioned through a conventional ECMO return cannula such that the proximal end of the flexible conduit is disposed within and proximal to the end of the ECMO return cannula, while the distal end of the flexible conduit is disposed in a patient's thoracic aorta to deliver oxygenated blood directly to the patient's thoracic aorta via one or more pores at the distal region of the flexible conduit to improve cerebral oxygenation, maintain systemic arterial pulsatility, and reduce the potential for end-organ injury.

    摘要： Implantable shunt devices and methods for draining cerebrospinal fluid from a patient's subarachnoid space include a shunt having opposed first and second ends, the second end being constructed to penetrate a wall of a sigmoid, transverse, straight, or sagittal sinus of the patient, a one-way valve, a hollow passageway extending between the second end and the one-way valve such that cerebrospinal fluid can be drained through the second end and out through the valve, and a mechanism coupled to the shunt and configured to anchor the shunt at a desired location proximal to the subarachnoid space.

    摘要： An extension cannula and in-line connector for use with a conventional ECMO return cannula is provided. The extension cannula includes a self-expanding conduit transitionable between a collapsed insertion state and an expanded, deployed state via a retractable sheath. The extension cannula may be inserted through a conventional ECMO return cannula such that the proximal end of the self-expanding conduit is disposed within and proximal to the end of the conventional ECMO cannula, while the distal end of the self-expanding conduit is disposed in a patient's thoracic aorta to improve cerebral oxygenation, maintain systemic arterial pulsatility, and reduce the potential for end-organ injury. The extension cannula and/or in-line connector may be used to permit delivery of additional interventional or vascular equipment using a single port of access, thereby avoiding complications associated with contemporary VA-ECMO.
