A perfusion cannula having a proximal section configured for attachment to a source of perfusion fluid, and a distal section configured for insertion in a blood vessel for delivering perfusion fluid to the blood vessel. In one embodiment, the cannula generally comprises a shaft having a proximal end, a distal end, a distal shaft section, and a proximal shaft section which is connected to the distal shaft section between the proximal and distal ends of the distal shaft section such that an acute angle is formed between the proximal shaft section and the proximal end of the distal shaft section. A lumen in the elongated shaft extends within the proximal shaft section and the distal shaft section to and in fluid communication with a port in the distal end of the distal shaft section. The lumen is configured for delivery of fluid, and may be configured for slidably receiving a guidewire therein. |
