The endoscopic imaging catheter includes reflecting and optical elements and an imaging element. The reflecting element reflects onto the imaging element through the optical element side and rear views of at least a portion, or the entire 360° view of a wall encircling an intrabody lumen around the axis of said the longitudinal channel.

Abstract: An auxiliary endoscopic imaging catheter is configured for insertion via a longitudinal working channel of an endoscopic. The endoscopic imaging catheter comprises a longitudinally extending tubular shaft having a proximal end, a distal end, and outer surface, and a longitudinal axis; one or more transparent or translucent elements positioned in the outer surface of the distal end of the shaft; and an imaging system comprising a reflector/refractor element and an imaging sensor, the imaging system being positioned interior of the distal end of the shaft. The reflector/refractor can be rotated or wobbled to obtain images of up to or over 360°. An illumination system is positioned on or in the distal end of the shaft, the illumination system being capable of illuminating a corporeal lumen or organ adjacent to the distal end.

Abstract: A dictionary at least partially spans a set of discrete q-length signals. The atoms of the dictionary are eigenvectors of a representation of a commutative subgroup of a finite symplectic group. The dictionary may be used for interpreting a radar signal, denoising a signal, compressing data, finding a sparse representation, deblurring at a signal finding a sparse representation of a signal, encoding a signal for communication, encoding a symbol for CDMF communication, classifying a data set and generating a random number.

Abstract: An endoscopic imaging catheter is configured for insertion via a longitudinal channel of an endoscopic. The endoscopic imaging catheter includes an optical element, an imaging element, and a rotatable tubular shaft comprises an optical element and an imaging element, which comprise a side-looking imaging component. An endoscopic imaging catheter may alternatively comprise reflecting and optical elements and an imaging element. The reflecting element reflects onto the imaging element through the optical element side and rear views of at least a portion, or the entire 360° view of a wall encircling an intrabody lumen around the axis of said the longitudinal channel.

Abstract: An endoscope including an outer elongate tube and an inner shaft that runs through the outer elongate tube and can be advanced independently of the outer tube. In addition, the endoscope includes an imaging capsule including at least one image capturing unit, mounted on a distal end of the inner shaft. The imaging capsule has a largest cross-section area smaller than the cross section area of the outer elongate tube.

Abstract: A method of examining internal body portions of patients. The method includes providing an imaging capsule including an image capturing unit, mounting the imaging capsule on a first elongate tube suitable for insertion into a body cavity, in a manner which prevents release of the imaging capsule from the first elongate tube within a body cavity, inserting the first elongate tube with the capsule mounted thereon into a patient, retracting the first elongate tube from the patient, separating the imaging capsule from the first elongate tube, disposing of the first elongate tube, mounting the imaging capsule on a second elongate tube and inserting the second elongate tube with the imaging capsule mounted thereon into a patient.

Abstract: Apparatus and method for navigating surgical tools within a body cavity. Embodiments of the invention are particularly useful for displacing a surgical tool within a body conduit such as an intestine. Embodiments comprise a balloon catheter having a shaft, and a surgical tool operable to slide along that shaft. In some embodiments the surgical tool comprises a second balloon catheter.

Abstract: A reflector for an endoscopic tool, which is made, for example of a framework or a balloon and reflects an image proximal to the tip to an imager at or near a tip of the endoscope. In some embodiments, the reflector distorts the image, which may be corrected using software.

Abstract: An endoscope sheath, comprising: an endoscope housing, configured for housing at least a distal end of an insertion tube of an endoscope and allowing the traversing of an endoscopic tool therethrough; and a tool deflector configured for deflecting said endoscopic tool by changing a direction of movement of said endoscopic tool in relation to a direction of movement of said distal end of said insertion tube.

Abstract: This application presents to an endoscope having a compact distal tip, and to a method for constructing same. In some embodiments one or more optical and sensing elements are mounted directly on an internal surface of a lumen within an external housing, which housing comprises an outer wall of the endoscope tip. Space saved by eliminating intervening containing elements can be used to enhance endoscope performance and/or reduce endoscope size.

Abstract: An invasive probe assembly including an invasive probe having a surface area and a tool carrier removably mounted on the invasive probe, including a substrate having an area smaller than 25% of the surface area of the probe and at least one tool mounted on the substrate. The layout of the substrate or of one or more of the at least one tool is optionally substantially different in different sectors of the circumference of the probe.

Abstract: A food administering apparatus including a feeding tube, having a distal outlet and proximal inlet, adapted for insertion of the distal outlet into the stomach of an adult patient while the proximal inlet is outside the patient, the tube being suitable for administering food or medicine from a proximal port to the distal outlet and at least one electrode mounted on the tube.

Abstract: Described herein are endoscopes having outer perimeter shapes configured to conform to the particular anatomy through which they will navigate. The outer perimeter cross-section of the endoscope may have one or more regions (e.g., longitudinal protuberances, edges, or narrow regions) that may allow the endoscope to conform with or fit within narrow or irregularly shaped regions of a body lumen, channel or passageway. Thus, the cross-sectional shape of the insertion tube of the endoscope may have an outer perimeter cross-section that is substantially D-shaped, oval, triangular, lobular, teardrop shaped, or the like. These non-circular cross-sectional shapes are matched approximately to the geometry of the region of the body into which the endoscope will be inserted, thereby allowing the endoscope to more precisely fit within a body lumen.

Abstract: A sheath assembly (100) for an invasive probe. The sheath assembly (100) includes an internal sheath (102) for covering a probe and at least one channel tube (112) external to the internal sheath (102), the channel tube (112) being foldable into a closed state in which the tube does not define a channel, or openable into an open state in which the tube defines a channel that extends along a portion of the sheath assembly (100).
