Implanting optical cavity structures
First Claim
1. A method, comprising:
- receiving input light into an implantable optical structure, the implantable optical structure comprising a first optical cavity and a second optical cavity, each of the first and second optical cavities including a container disposed between opposing reflectors, the container of the first optical cavity having an opening allowing entry of bodily fluids and the container of the second optical cavity being closed and containing a reference fluid;
transferring bodily fluid between an exterior and interior of the container of the first optical cavity through the opening;
reflecting light input into the first optical cavity more than once across the container of the first optical cavity;
reflecting light input into the second optical cavity more than once across the container of the second optical cavity;
photosensing output light from the first optical cavity and providing first optical cavity photosensing results; and
photosensing output light from the second optical cavity and providing second optical cavity photosensing results.

Abstract
An implantable product includes an optical cavity structure with first and second parts, each of which can operate as an optical cavity. The first part includes a container with at least one opening through which bodily fluid can transfer between the container'"'"'s interior and exterior when the product is implanted in a body. The second part includes a container that is closed and contains a reference fluid. The implantable product can also include one or both of a light source component and a photosensing component. Photosensed quantities from the first part'"'"'s output light can be adjusted based on photosensed quantities from the second part'"'"'s output light. Both parts can have their light interface surfaces aligned so that they both receive input light from a light source component and both provide output light to a photosensing component.

12. A method, comprising:
-
receiving input light from a light source through a first light interface surface of an implantable optical structure, the first light interface surface common to a first optical cavity and a second optical cavity, each of the first and second optical cavities having a container disposed between opposing reflectors, the container of the first optical cavity having an opening allowing entry of bodily fluids and the container of the second optical cavity being closed and containing a reference fluid; transferring bodily fluid between an exterior and interior of the container of the first optical cavity through the opening; reflecting light received through the first light interface surface multiple times between the opposing reflectors of the first optical cavity and through the container of the first optical cavity; reflecting light received through the first light interface surface multiple times between the opposing reflectors of the second optical cavity and through the container of the second optical cavity; emitting output light from the first and second optical cavities through a second light interface surface which is common to the first optical cavity and the second optical cavity. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
