发明名称 Method and device for the treatment of glaucoma
摘要 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the Schlemm's canal and the implant and upon releasing the implant at its determined location, the catheter can be withdrawn from the Schlemm's canal.

主权项 1. A device for treatment of glaucoma, comprising: a catheter having proximal and distal portions; a flexible tubular implant configured with at least one connecting part extending along an axial extension of the implant for bearing at an inner wall at the Schlemm's canal, and radial ring members arranged in axial direction and connected to the connecting part and spaced-apart from each other by gaps, said implant placed entirely over the distal portion of the catheter for insertion into the Schlemm's canal in a direction of a target site, wherein the distal portion has spaced-apart bores in communication with an interior space of both, the catheter and the implant for injecting a medium under pressure at the target site to expand the implant and release the implant from the catheter at the target site to thereby allow withdrawal of the catheter, wherein the proximate portion is connected to a pressure source.
