  • Patent number: 8951221
    Abstract: The invention relates to a method and device for the treatment of glaucoma, though insertion of an implant into the lumen of the Schlemm's canal to realize proper drainage of the aqueous humor, which implant is brought into its position in the Schlemm's canal by means of a catheter having a distal and a proximate portion and provided with a number of pores through which a gaseous or fluid medium which comes from a pressure source can emerge during insertion of the catheter carrying the implant into the Schlemm's canal, and while the catheter is being inserted into the Schlemm's canal the gaseous or fluid medium is released under pressure thereby expanding the Schlemm's canal and the implant and upon releasing the implant at its determined location, the catheter can be withdrawn from the Schlemm's canal.
