Abstract: A vascular device and method for positioning a vascular device within a patient's vasculature for use in extracorporeal membrane oxygenation (ECMO) are described that make use of one or more ultrasound transducers supported by the vascular device to visualize the location and orientation of the vascular device. An ultrasound transducer may be provided at a port of the vascular device that infuses oxygenated blood into the patient's vasculature to allow the operator of the vascular device to align the port with a particular structure in the patient's body, such as the tricuspid valve of the heart. Another ultrasound transducer may additionally or alternatively be provided at a distal end of the vascular device to facilitate insertion of the vascular device with minimal injury or trauma to the patient and to allow advancement of the device to the correct location. The imaging may be continuous and may be provided in real-time.
