  • Patent number: 10602960
    Abstract: A device and method are described for navigating and positioning a central venous catheter into the venous system using two different modes of location. For example, a peripherally inserted central catheter (“PICC”) may be navigated and positioned within the superior vena cava. A light emitting element is used in the first mode to navigate the PICC to the superior vena cava. To improve visibility during navigation, the light emitted from the light emitting element may include a narrow range of wavelengths that generally matches the wavelengths of light that are transmissable through a light absorbing material defining the wall of the catheter. A conductive medium is used in the second mode to monitor an ECG signal in order to position the PICC in the superior vena cava. One advantage of this procedure is that X-ray visualization can be eliminated to reduce the danger associated with X-rays.

  • Patent number: 10338310
    Abstract: The present invention provides a light transmittable and tissue integration integrable biofiber device including a plurality of biofibers. The plurality of biofibers consist a single bare fiber or a single constructed fiber. The single constructed fiber consists a core layer and either a single cladding layer or a plurality of cladding layers, and the cladding layer clads and fuses a circumferential surface of the core layer. Each of the plurality of biofibers comprises a light receiving end and a light emitting end, a light radiates through the light receiving end and the light is emitted from the a light emitting end. Therefore, the biofiber device of the present invention may simultaneously accomplish light transmittable and tissue integrable purposes to facilitate light therapy, optical gene therapy and optogenetics.

  • Patent number: 10272261
    Abstract: The invention provides a photodynamic therapy-based method for treating ocular glaucoma. A photosensitizer, for example, a benzoporphyrin derivative photosensitizer, is administered to a mammal either having or at risk of developing ocular glaucoma. The photosensitizer, when present in the ciliary body, is activated by light, for example, light from a laser. The treatment results in a reduction of intraocular pressure within the treated eye, which can persist for a prolonged period of time.

  • Patent number: 10265123
    Abstract: A catheter enables real-time light measurements, for example, without limitation, diffuse reflectance, fluorescence, etc., from biological materials, such as tissue (including blood), while performing RF ablation. The catheter tip design isolates illumination and collection paths within the tip electrode such that light for illuminating the tissue of interest (e.g., cardiac tissue or blood) is isolated within the tip electrode from light that returns from the tissue to the catheter tip, and vice versa. Such a design advantageously avoids saturation of the optical detector, and ensures diffusion of the illumination light within the medium of interest. The catheter has a catheter body and a tip electrode with a shell wall and a hollow cavity. The shell wall has at least an illumination opening and a collection opening.
