Abstract
A phacoemulsification irrigation sleeve having a body configured to operatively connect to a phacoemulsification needle. The body has proximal and distal ends and defines a passageway for liquid. A first irrigation port is formed in the body between its proximal and distal ends. The body is slit to define a first flap configured to swing away from the first irrigation port in response to pressure of fluid flowing in the passageway to thereby reduce resistance of fluid flow through the first irrigation port. The first flap, when swung away from the first irrigation port, is oriented to direct fluid flowing through the first irrigation port in a direction from the proximal end of the body toward the distal end of the body.
