摘要
Disclosed herein is an apparatus for insertion in an eye of a patient for aspirating material from the eye in the treatment of an ocular condition, the apparatus comprising a needle disposed at a distal end of the apparatus, an aspiration channel extending from a distal aperture of the needle to a proximal end of the apparatus, and an irrigation sleeve coaxially disposed about the needle. The aspiration channel comprises a proximal portion having a first diameter, a bypass portion having a second diameter and at least one bypass port, and a distal portion having a third diameter. The second diameter is larger than the first diameter. The irrigation sleeve and the needle form an annular irrigation passageway therebetween. The bypass port is shaped and configured to establish fluid communication between the irrigation passageway and the aspiration channel.
