CA 2349590

A punctum plug (100) includes a proximal head (102), a distal body (106), a shaft (104) between the head (102), and the body (106). The shaft (104) of the plug (100) is provided with one or more foldable portions, thereby permitting the length of the shaft to vary depending upon the degree to which the folds are folded or unfolded. In addition, the folds permit the wall of the shaft to easily bend, permitting the head and body of the plug to lie along different axes. As a result, the plug is shaped to accommodate both relatively long and short vertical puncta. The body of the plug may be angled relative to the head to accommodate a variety of anatomical structures.

L'invention concerne un bouchon pour point lacrymal (100), qui comprend une tête proximale (102), un corps distal (106), un axe (104) entre la tête (102) et le corps (106). L'axe (104) du bouchon comporte une ou plusieurs parties pliables, ce qui permet de varier la longueur de l'axe en fonction du degré selon lequel les pliures sont faites et défaites. Par ailleurs, les pliures permettent de courber facilement la paroi de l'axe, moyennant quoi la tête et le corps du bouchon peuvent prendre des orientations différentes. En conséquence, le bouchon est dimensionné pour s'adapter aux points lacrymaux verticaux relativement longs et courts. Le corps du bouchon peut former un angle avec la tête, pour s'adapter à une variété de structures anatomiques.
