Abstract

A device for the treatment of glaucoma with a laser catheter and a light-conducting fiber arrangement, into the proximal end of which light can be coupled and at the distal end of which a light-emerging surface is provided which, during the treatment, is opposite to a bent stent, which is disposed in Schlemm'"'"'s canal, the stent having an essentially triangular cross section in such a manner, that the light-emerging surface is essentially congruent with the opposite side surface of the stent in Schlemm'"'"'s canal.

Claims

1. A device for the treatment of glaucoma with a laser catheter and a light-conducting fiber arrangement, into the proximal end of which light can be coupled and at the distal end of which a light-emerging surface is provided which, during the treatment, is opposite to a bent stent, which is disposed in Schlemm'"'"'s canal, wherein the stent has an essentially triangular cross section in such a manner, that the light-emerging surface is essentially congruent with the opposite side surface of the stent in Schlemm'"'"'s canal.

2. The device of claim 1, wherein the light-emerging surface forms the bottom of an adjusting recess of the fiber arrangement, which embraces the stent at the top and at the bottom.

3. The device of claim 1, wherein the inner side surface, lying on the inside of the arc opposite to the light-emerging surface of the laser catheter, forms an angle of about 115°

with the narrow base surface and the outer surface, lying on the outside of the arc, forms an angle of about 40°

with the base surface of the stent.

4. The device of claim 1, wherein the stent has a bending radius of about 7 mm.
