Abstract: A method of imaging a vessel with a catheter includes positioning an imaging tip in a reinforced terminal section of an outer sheath of the catheter, inserting the catheter into a vessel, and performing near infrared spectroscopy of the vessel by retracting the imaging tip to a retracted position proximally spaced from the reinforced terminal section of the outer sheath, transmitting near infrared light from the imaging tip to the vessel wall via the outer sheath, and collecting near infrared light from the vessel wall at the imaging tip via the outer sheath. Transmitting and collecting may be performed after retracting the cable and while the imaging tip is rotated and translated proximally from the retracted position along the outer sheath. Ultrasound energy may be transmitted to the vessel from a transducer on the imaging tip and received from the vessel at the transducer.

Abstract: A method for monitoring a flowrate of cerebrospinal fluid (CSF) in a ventriculo-peritoneal (VP) shunt implanted in a human patient includes: (i) receiving, at a device external to the human patient, data sensed by a plurality of sensors within the device and positioned relative to the VP shunt to drain excess cerebrospinal fluid from the human patient's brain; (2) determining, by the device and based on the sensed data, a rate of flow of the CSF in the VP shunt; and (3) transmitting (e.g., wirelessly), by the device, data indicating the rate of flow to a computing server.

Abstract: A system useful for in vivo and ex vivo spectroscopy comprises a water source connected to supply water through a passage to an outlet at a flow rate sufficient to issue a laminar water jet from the outlet, a light source operative to emit a light beam that is guided to a sample by the water jet, and an analysis unit connected to receive collected light that has been emitted from the sample into the water jet and operable to analyze the collected light. Some embodiments provide endoscopes with integrated light guides.

Abstract: A catheter-based imaging apparatus comprises a catheter having a proximal end and a distal end. An optical emitter is configured to emit optical excitation signals from a distal portion of the catheter. One or more ultrasound transducers are configured for: (a) transmission of acoustic excitation signals from the distal portion of the catheter; and (b) detection of ultrasound response signals from an object of interest at or near to the distal portion of the catheter at frequencies which include a lower receive frequency at least as low as 10 MHz and a higher receive frequency at least as high as 35 MHz. The one or more ultrasound transducers are thereby configured to detect response signals comprising photoacoustic response signals from the object of interest at the lower receive frequency and high resolution imaging signals from the object of interest at the higher receive frequency.

Abstract: Exemplary method and apparatus for diagnosing or characterizing an inflammation within an anatomical structure can be provided. For example, using at least one source arrangement, it is possible to provide at least one first electro-magnetic radiation to the anatomical structure at at least one first wavelength in vivo. With at least one detector arrangement, it is possible to detect at least one second electro-magnetic radiation at at least one second wavelength provided from the anatomical structure. The second radiation can be associated with the first radiation, and the first wavelength can be shorter than the second wavelength. The second radiation can be provided from the anatomical structure due to at least one change in the anatomical structure caused by the inflammation without providing an artificial fluorescence substance. At least one computer arrangement can be used to determine at least one characteristic of the structure based on the second radiation to diagnose or characterize the inflammation within the anatomical structure.
