In general, the disclosure is directed toward transmitting radiant energy across a boundary of a medical device via an optical feedthrough. A system for transmitting radiant energy across a boundary of a medical device includes a first functional module of a medical device, a second functional module of the medical device, an optical feedthrough assembly coupled to the first functional module, and a radiant energy source that emits a beam through the optical feedthrough assembly to perform a manufacturing process on the first functional module and the second functional module.

Optical feedthrough for medical devices

A radiopaque marker for inclusion within an implantable medical device (IMD) may comprise one or more radiopaque articles selected from a predetermined set of radiopaque articles. The one or more radiopaque articles may be carried by an object formed of or including, a desiccant. The predetermined set of radiopaque articles may undergo a single qualification process that approves the use of any combination of one or more of the articles as a radiopaque marker within an IMD. This allows a potentially-limitless number of markers to be made available based on a single qualification process. The radiopaque marker may serve to provide information such as the make, model, and feature set of the device.

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.
