Abstract
A glaucoma drainage implant comprising a pressure relief valve via which aqueous humor can be drained. The pressure relief valve has a pressure relief flap which is movably connected with a base plate of the implant, which is to be embedded in a sclera, wherein the pressure relief flap has an actuation area by means of which the pressure relief flap can be mobilized non-invasively during a post-operative healing phase or thereafter. The actuation area is preferably designed as a thermomechanically active area.

A glaucoma drainage implant comprising a pressure relief valve via which aqueous humor can be drained, wherein the pressure relief valve has a pressure relief flap which is movably connected with a base plate of the implant, which is to be embedded in a sclera, wherein the pressure relief flap has an actuation area by means of which the pressure relief flap can be mobilized non-invasively during a post-operative healing phase or thereafter, and wherein the actuation area has a thermomechanically active area comprising a shape-memory material with a two-way memory effect, such that the pressure relief flap can be mobilized non-invasively by a change in electromagnetic radiation.
A glaucoma drainage implant comprising a pressure relief valve via which aqueous humor can be drained, wherein the pressure relief valve has a pressure relief flap which is movably connected with a base plate of the implant, which is to be embedded in a sclera, wherein the pressure relief flap has an actuation area by means of which the pressure relief flap can be mobilized non-invasively during a post-operative healing phase or thereafter, and wherein the actuation area has a thermomechanically active area comprising a shape-memory material with a two-way memory effect, such that the pressure relief flap can be mobilized non-invasively by a change in temperature.
A glaucoma drainage implant comprising a pressure relief valve via which aqueous humor can be drained, wherein the pressure relief valve has a pressure relief flap which is movably connected with a base plate of the implant, which is to be embedded in a sclera, wherein the pressure relief flap has an actuation area by means of which the pressure relief flap can be mobilized non-invasively during a post-operative healing phase or thereafter, and wherein the actuation area has a thermomechanically active area comprising a shape-memory material with a two-way memory effect, such that the pressure relief flap can be mobilized non-invasively by a change in induction heating.
A glaucoma drainage implant comprising a pressure relief valve via which aqueous humor can be drained, wherein the pressure relief valve has a pressure relief flap which is movably connected with a base plate of the implant, which is to be embedded in a sclera wherein the pressure relief flap has an actuation area b means of which the pressure relief flap can be mobilized non-invasively during a post-operative healing phase or thereafter, wherein the pressure relief flap is movably connected with the base plate via an attachment area which serves as a flexure joint.
A glaucoma drainage implant comprising a pressure relief valve via which aqueous humor can be drained, wherein the pressure relief valve has a pressure relief flap which is movably connected with a base plate of the implant, which is to be embedded in a sclera, wherein the pressure relief flap has an actuation area by means of which the pressure relief flap can be mobilized non-invasively during a post-operative healing phase or thereafter, and wherein the base plate is step-shaped, the base plate having a greater thickness in an attachment area of the pressure relief flap than in an opening region of the pressure relief flap opposite the attachment area.
A method of implanting a glaucoma drainage implant into a human or animal eye, the method comprising the steps of:
- creating a scleral bed in a sclera of the eye, said scleral bed having a drainage channel;
- implanting a glaucoma drainage implant into the scleral bed in such a way that the base plate closes the scleral bed water-tightly, the glaucoma drainage implant comprising a pressure relief valve via which aqueous humor can be drained, wherein the pressure relief valve has a pressure relief flap which is movably connected with a base plate of the implant, which is to be embedded in a sclera, and wherein the pressure relief flap has an actuation area by means of which the pressure relief flap can be mobilized non-invasively during a post-operative healing phase or thereafter;
- and
- non-invasively mobilizing the pressure relief flap, during or after a post-operative healing phase for the implant;
- wherein the step of non-invasively mobilizing is by means of an energy source which generates a temperature gradient.
