In general, the disclosure is directed toward releasing material within a medical device via an optical feedthrough. A system for releasing material with a medical device comprises a cup that holds a material, wherein the cup includes a discharge port, a seal disc that seals the material within the cup, an optical feedthrough assembly coupled to the cup, a shell that defines a chamber within a medical device, wherein the optical feedthrough assembly is coupled to the shell, and a radiant energy source that shines a beam through the optical feedthrough assembly to puncture the seal disc to allow the material to enter the chamber via the discharge port.

1. A system comprising: a cup that holds a material, wherein the cup includes a discharge port;a seal disc that seals the material within the cup;an optical feedthrough assembly coupled to the cup;a shell that defines a chamber within a medical device, wherein the optical feedthrough assembly is coupled to the shell; anda radiant energy source that shines a beam through the optical feedthrough assembly to puncture the seal disc to allow the material to enter the chamber via the discharge port. 2. The system of claim 1, wherein the material comprises a propellant, the chamber comprises a propellant chamber, and the medical device comprises a therapeutic agent delivery device. 3. The system of claim 1, wherein the shell comprises at least a portion of an outer housing of the medical device. 4. The system of claim 3, wherein the optical feedthrough assembly is coupled to the outer housing of the medical device, and wherein an interface between the outer housing and the optical feedthrough assembly is hermetically sealed. 5. The system of claim 1, wherein the medical device comprises an implantable medical device. 6. The system of claim 1, wherein the medical device comprises a therapeutic agent delivery device. 7. The system of claim 1, wherein the optical feedthrough assembly comprises an optical window that allows the beam through the optical feedthrough assembly. 8. The system of claim 7, wherein the optical window comprises at least one of glass, sapphire, polymer, or a crystalline material. 9. The system of claim 7, wherein the cup comprises a lip configured to accept the sealing disc, and the sealing disc seals the material within the cup at a location of the lip. 10. The system of claim 7, wherein the cup comprises a lip configured to accept the optical feedthrough, and the optical feedthrough assembly is coupled to the cup at a location of the lip. 11. The system of claim 7, wherein the optical feedthrough assembly comprises a lip configured to mate with an aperture defined by the shell and the optical feedthrough assembly is coupled to the shell at a location of the lip. 12. The system of claim 7, wherein the cup comprises a first cup, the material comprises a first material, the seal disc comprises a first seal disc, and the beam comprises a first beam, the system further comprising: a second cup that holds a second material; anda second seal disc that seals the second material within the second cup, wherein the optical feedthrough assembly is coupled to the second cup, and the radiant energy source shines a second beam through the optical feedthrough assembly to puncture the second seal disc to allow the second material to enter the chamber via the discharge port. 13. A method of using the system of claim 1, the method comprising: sealing a material within a cup using a seal disc, wherein the cup includes a discharge port;coupling an optical feedthrough assembly to the cup;coupling the optical feedthrough assembly to a shell that defines a chamber within a medical device; andapplying radiant energy through the optical feedthrough assembly to puncture the seal disc to allow the material to enter the chamber via the discharge port. 14. The method of claim 13, further comprising filling the cup with a measured amount of the material. 15. The method of claim 13, wherein sealing the material with the cup comprises welding the seal disc to the cup at a location between the material and the discharge port. 16. The method of claim 13, wherein coupling the optical feedthrough assembly to the cup comprises welding the optical feedthrough assembly to the cup. 17. The method of claim 13, wherein coupling the optical feedthrough assembly to the shell comprises welding the optical feedthrough assembly to the shell. 18. The method of claim 13, wherein the cup comprises a first cup, the material comprises a first material, and the seal disc comprises a first seal disc, the method further comprising: sealing a second material within a second cup using a second seal disc;coupling the optical feedthrough assembly to the second cup; andapplying radiant energy through the optical feedthrough assembly to puncture the second seal disc to allow the second material to enter the chamber via the discharge port.
