The present disclosure relates to devices, systems and methods for positioning a neuromodulation device at a treatment site and evaluating the effects of therapeutic energy delivery applied to tissue in a patient. Before, during and/or after therapeutic energy delivery, a system can monitor parameters or values relevant to efficacious neuromodulation by emitting and detecting diagnostic energy at the treatment site. Feedback provided to an operator is based on the monitored values and relates to a relative position of the treatment device at the treatment site, as well as assessment of the likelihood that a completed treatment was technically successful.

Controlled neuromodulation systems and methods of use

An optical module providing laser diodes (LD) and monitor PDs is disclosed. The LDs and monitor PDs are mounted on a module substrate that also mounts a resin body. The resin body includes a mirror surface which causes a total inner reflection for the optical beams coming from the LDs toward the inner fibers set in one side of the resin body. The mirror surface further provides a blip to refract portions of the optical beams toward the monitor PDs.

Optical module with beam splitter on reflecting surface

A pluggable optical transceiver with the CFP type and the MT ferrule is disclosed. The optical transceiver provides in a rear of the optical receptacle a mechanism to push frontward the MT ferrule set in the optical receptacle and to shield the inside of the optical transceiver. Inner fibers connecting the MT ferrule with another MT ferrule assembled with optical devices pass the mechanism, which may be a metal plate with the elastic function and/or a coil spring combined with a holder to hold the MT ferrule.

An optical transceiver of one embodiment includes a transmitter optical subassembly to transmit an optical signal, a receiver optical subassembly to receive an optical signal, a mother board, a daughter board, and a housing. The mother board mounts electronic circuits that electrically communicate with the optical transmitter optical subassembly and the receiver optical subassembly. The daughter board mounts other electronic circuits that electrically communicate with the optical transmitter optical subassembly and the receiver optical subassembly. The daughter board has an extra area mounting a portion of the other electronic circuits. The housing defines a space for installing the optical transmitter optical subassembly, the receiver optical subassembly, the mother board, and the daughter board. The extra area is disposed outside the space.

The present disclosure relates to methods and systems relating to temperature dependent photoacoustic imaging are provided. In such methods and systems, a tissue sample may be exposed to thermal energy and electromagnetic radiation to generate an acoustic signal, which may be detected. The amplitude of the acoustic signal may be determined and correlated with a tissue property, such as the presence or absence of macrophages or foam cells.

Temperature dependent photoacoustic imaging

An optical transceiver implemented with a tunable LD is disclosed. The tunable LD is installed within a TOSA (Transmitter Optical Subassembly). The optical transceiver provides two circuit boards arranged in the up-and-down relation. The TOSA is primarily connected to the second board but signals to drive the tunable LD are carried on an FPC board directly connected to the first board that mounts a driver circuit for the tunable LD.
