1. Apparatus for insertion into an operative position relative to an aperture within a body of a patient without requiring a closure stitch for entry of the apparatus into the body, said apparatus comprising: a needle for insertion in tissue of the body and forming a needle track in the tissue upon advancement of the needle in the tissue; a treatment device; and
means for connecting the treatment device to the needle so that the treatment device can be transported with said needle through said needle track to said operative position, said treatment device comprising a deformable body having shape retentive memory, said deformable body being a wire-form body that forms a plurality of partial loops when in a relaxed state and being deformable to a deformed state wherein the plurality of partial loops of the wire-form body are flattened, said apparatus and needle track being of sufficiently small size so as to permit self-closure of the needle track and not require a closure stitch, wherein said treatment device is adapted for placement in the eye of a patient to dilate a pupil thereof, wherein, in the relaxed state, the wire-form body forms the plurality of partial loops with respective openings of the plurality of partial loops oriented such that each of the respective openings can face an edge of an iris with respective legs of the plurality of loops extending in the same direction for straddling the edge of the iris such that an inner concave surface of the wire-form body can engage the edge of the iris to dilate the pupil of the iris, and wherein, in the relaxed state, said wire-form body forms a straight portion extending uniformly in one direction from a first of the plurality of partial loops to a second of the plurality of partial loops to connect the first and second partial loops. |
