Intraocular shunt manufacture
An intraocular shunt can be manufactured using a system that includes a liquid bath and a wire, which is moved through the bath. When moved through the bath, the wire is coated with a material, such as gelatin. For example, the liquid bath can have a top layer, including water, and a bottom layer, including gelatin. The coated wire passes through an aperture formed in a plate component of the system. The gelatin can be dried on the wire in a humidity-controlled space, thereby forming the shunt.
1. A system, for manufacturing a gelatin shunt, comprising:
a motor;
a wire operably coupled to the motor for movement of the wire;
a temperature controllable bath;
an aperture plate situated above a bottom portion of the bath; and
an ultrasonic fogger, positioned above the plate, for providing a fog;
wherein the system is configured such that the wire moves through the bath and the aperture plate and through the fog.
2. The system of claim 1 , wherein a path of the wire extends downwardly toward a bottom of the bath and then vertically out of the bath.
3. The system of claim 1 , wherein the wire moves vertically through the fog.
4. The system of claim 1 , wherein the aperture plate is situated in a top portion of the bath.
5. The system of claim 1 , wherein the wire moves through an aperture of the aperture plate.
6. The system of claim 5 , further comprising a first camera positioned to view the wire at the aperture as the wire moves through the aperture plate.
7. The system of claim 6 , further comprising a second camera and software configured to provide, based on data from the second camera, a thickness measurement of a coating on the wire.
8. The system of claim 7 , further comprising a liquid gelatin filling a bottom layer of the bath and water filling a top layer of the bath.
9. A system, for manufacturing an intraocular shunt, comprising:
a container configured to hold a liquid material for forming a shunt;
a plate disposed above a bottom portion of the container, the plate comprising an aperture having a cross-sectional dimension; and
a wire, extending into the container and through the aperture, being movable relative to the bottom portion of the container;
wherein the wire can be pulled from the bottom portion through the aperture to coat the wire with a liquid material such that a cross-sectional dimension of the material is limited by the cross-sectional dimension of the aperture.
10. The system of claim 9 , further comprising a motor operably coupled to the wire for driving movement of the wire through the container and aperture.
11. The system of claim 9 , further comprising a temperature control unit for controlling a temperature of liquid material within the container.
12. The system of claim 9 , further comprising a pulley, disposed within the container and coupled to the wire for redirecting the wire through the aperture.
13. The system of claim 12 , wherein a path of the wire extends downwardly toward a bottom of the container, around the pulley, and then vertically out of the container through the aperture.
14. The system of claim 9 , further comprising an ultrasonic fogger, positioned above the container, configured to emit a fog for maintaining a desired humidity for the system.
15. The system of claim 14 , wherein the wire moves vertically through the fog.
16. The system of claim 9 , further comprising a first camera positioned to view the wire as it moves through the aperture plate.
17. The system of claim 9 , further comprising a second camera and software configured to provide, based on data from the second camera, a thickness measurement of a coating on the wire.
18. The system of claim 9 , wherein the plate is disposed within the container.
19. The system of claim 18 , further comprising liquid material, wherein the plate is submerged in the liquid material.
20. The system of claim 19 , wherein the liquid material comprises a liquid gelatin filling a bottom layer of a bath and water filling a top layer of the bath, the plate being situated above the bottom layer.
