Abstract
Glaucoma shunts comprising an elongate body with an outer surface and an inner surface, the elongate body comprising an inner wall that defines a lumen spanning a length of the elongate body are disclosed herein. Also disclosed are methods of decreasing intraocular pressure in an eye, the method comprising inserting at least a portion of a glaucoma shunt into an anterior chamber of the eye, and draining aqueous humour from the anterior chamber through the lumen.
Claims17
An injection device for delivering a glaucoma shunt into a part of an eye, the injection device comprising:
- a body with a front end and an opposing rear end, the body extending along a first axis;
- an adjustable head connected to the front end of the body, the adjustable head comprising an outer wall defining an inner cavity, and secured to the front end of the body by an adjustable joint, wherein the adjustable head is adjustable via the adjustable joint to extend along a second axis, wherein the second axis forms an angle relative to the first axis, and wherein the angle of the adjustable head can be adjusted while the adjustable head remains connected to the front end of the body;
- an actuator connected to the adjustable head via an internal structure located within the inner cavity;
- a needle which is mounted to the internal structure, the needle being hollowed and extending along the second axis;
- and
- a glaucoma shunt stored within the hollow needle,
- wherein movement of the actuator from one position to another position causes the internal structure and the needle to move relatively to the adjustable head in a direction away from the eye, while the adjustable head and the needle remain on the second axis, leaving the glaucoma shunt in the part of the eye.
A method of decreasing intraocular pressure in an eye, comprising:
- providing an injection device including
- a body with a front end and an opposing rear end, the body extending along a first axis;
- an adjustable head connected to the front end of the body, the adjustable head comprising an outer wall defining an inner cavity, and secured to the front end of the body by an adjustable joint, wherein the adjustable head is adjustable via the adjustable joint to extend along a second axis, wherein the second axis forms an angle relative to the first axis, and wherein the angle of the adjustable head can be adjusted while the adjustable head remains connected to the front end of the body;
- an actuator connected to the adjustable head via an internal structure located within the inner cavity;
- a needle which is mounted to the internal structure, the needle being hollowed and extending along the second axis;
- and
- a glaucoma shunt stored within the hollow needle,
- adjusting the joint to position the adjustable head at said angle relative to the first axis;
- positioning the head at a desired shunt insertion location against the eye;
- inserting the needle into the eye;
- and
- moving the actuator from one position to another position causing the internal structure and the needle to move relative to the adjustable head and in a direction away from the eye, along the second axis, thereby leaving the glaucoma shunt in the eye.
