Abstract: A stylet assembly and method of forming an in vivo image acquiring stylet assembly. The stylet assembly includes an elongate flexible body and an image acquiring device that is supported at a location that is offset from an in vivo facing terminal end of the stylet assembly. A terminal end portion of the stylet assembly is defined by a manipulator that is oriented to extend in a crossing direction relative to a longitudinal axis of the elongate body. The terminal end portion of the stylet assembly is steerable relative to the elongate body and is operable to manipulate positions or adjacent anatomy and/or effectuate guidance of the imaging device relative thereto during use.

Abstract: Apparatus, including a tube having proximal and distal ends and an internal lumen. The distal end may bend up to 270°, and the tube may be inserted into an eye. A planar resilient strip, having proximal and distal ends, is inserted into the internal lumen, and the strip distal end is fixed to the tube distal end. A coil spring is fixed to the strip proximal end so that a coil spring symmetry axis is coplanar with the strip. A camera, mounted with the strip distal end, images the eye interior. A wire is fixed to the strip distal end, so that a predetermined force on the wire causes the tube distal end to bend by a preset angle. A magnetometer at the tube proximal end is configured, when a nonvarying magnetic field traverses it, to provide a signal that, when taken with the preset angle, indicates a camera orientation.

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.
