Abstract:
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.
