Abstract: An endoscope can include a substantially rigid elongate body. A visualization channel can extend through the elongate body. An elongate viewing instrument that can advance distally and retract proximally through a visualization channel of the elongate body. The elongate viewing instrument can include a distal portion that is pre-biased to assume a curved shape when the distal portion is unconfined. The distal portion can curve when the distal portion is advanced distally to exit the visualization channel and can straighten when the distal portion is retracted proximally to enter the visualization channel. A distal end of the elongate viewing instrument can further include a light port that is configured to illuminate a target and provide an image of the illuminated target.

Abstract: Adjustable distal tips of cold plasma generating devices configured for introduction to and operation within narrow intra-body confines. In some embodiments, a plasma delivery tip of a cold plasma generating device is expandable from a compact delivery configuration, allowing device operation with plasma plume parameters difficult to achieve within size constraints of a narrow delivery catheter and/or endoscope working channel. Additionally or alternatively, in some embodiments, operating parameters of a plasma delivery tip are adjustable to tune characteristics of the plasma plume. Adjustable parameters optionally include, for example: lumen diameter, lumen aperture shape/direction, discharge electrode geometry, dielectric barrier characteristics, and/or relative placement of these components, including placement relative to a stream of ionizing gas. In some embodiments, plasma delivery tip elements are adapted to assist device navigation and/or tissue penetration.

Abstract: Described herein are methods, devices, and support structures for assembling optical fibers in catheter tips and facilitating alignment and structural support. A method for assembling a plurality of optical fibers and lenses in a support structure for an ablation catheter includes providing a support structure with a proximal end, a body, and a distal end, wherein the distal end includes a plurality of alignment orifices or slits. A plurality of optical fibers are threaded through the alignment orifices or slits, such that each optical fiber is threaded through a corresponding alignment orifice or slit. An adhesive material is applied at each alignment orifice or slit to secure the optical fibers, and the plurality of optical fibers are then cleaved at the distal end to remove portions of the fibers extending out of the distal end. Finally, a lens is attached to each of the ends of the plurality of optical fibers.
