Abstract: A cannula includes a hollow cylindrical body which is open at one end and closed at the other end. A slot extends from the open end toward the closed end, terminating with an opening that is larger in width than the slot, the width being measured in a direction perpendicular to the longitudinal direction in which the slot extends. The opening allows the passage of a guide wire for relative sliding. The configuration of the cannula is such that the end of the wire coming out of the cannula through the opening cannot, once inserted into the openings, penetrate into the part of the cannula beyond the opening between the latter and the closed end of the cannula. Related methods for inserting a tube shaped probe into a tear duct are disclosed.

Abstract: A bicanalicular probe intended to be inserted into the nasolacrimal duct of a patient including a central tubular part 1 made from a material compatible with insertion into the human body, preferably silicone, and two termination parts 4, 5 each fixed to one end of the central tubular part 1, characterized in that the two thickened parts 6, 7 project from the central tubular part, the two thickened parts being firstly at a distance from each other and secondly each at a distance from the ends 2, 3 where the termination parts are attached.
Abstract: A composite product, especially an implant, includes at least one base element or matrix of a first polymer material coated with a coating of a second polymer material or of a second material based on reactive prepolymers. There is at least one base element or matrix coated with the coating which exhibits openings passing through it from one side to the other. The softening temperature of the second polymer material or the reaction/crosslinking temperature of the second material based on reactive prepolymers being lower than the softening temperature of the first polymer material.
