  • Patent number: 4784138
    Abstract: The retinal tack includes a generally conical, sharply pointed forward end portion for piercing through the retina, choroid, and sclera, an elongated, generally cylindrical retaining portion having a longitudinal dimension approximating the thickness of a patient's retina, choroid, and sclera and including one or more peripheral grooves for receiving sclera tissue displaced during insertion of the forward end portion, and an enlarged head having a radially extending flange portion for engaging the retina in the area of the opening formed in the retina. The tack is carried in the tip of a tubular probe selectively connected in fluid communication with sources of negative and positive pressures and the head includes a seat portion which sealingly engages a complementary seat in the probe tip when a negative pressure is applied to the probe.
