  • Perfusion catheter with flow amplifier
    Patent number: 5284473
    Abstract: A perfusion catheter is provided which increases the static pressure gradient across a portion of the catheter so that the flow through the catheter having the flow amplifier is greater than the flow through an unamplified catheter. A low pressure region is created at or downstream of the perfusion ports so that a greater volume of blood is drawn in and subsequently discharged through the distal end of the catheter.
