  • Publication number: 20130281781
    Abstract: This invention relates generally to an endoscope accessory. This device uses an overtube with an inflatable positioning ring that can be inflated after placement of the overtube just proximal to the tip of the endoscope or echoendoscope. A catheter with an occlusion balloon at its free endportion is carried by the overtube and extends beyond the tip of the endoscope, distal to the part of the body cavity that needs to be examined. Inflation of this balloon together with positioning ring creates a closed space within the body cavity that can be filled with air or water for improving the quality of the examination with regular endoscope of echoendoscope, respectively, while reducing the examination complications.

  • Publication number: 20120004506
    Abstract: In accordance with exemplary embodiments of the present disclosure, device and method can be provided which can facilitate imaging of biological tissues, e.g., luminal organs in vivo, using optical techniques. The exemplary device can include different designs an features of one or more catheters, which can illuminate the tissues, and collect signals from the inside of the lumen. In another exemplary embodiment according to the present disclosure, a balloon-catheter can be provided with the flexible neck, which can absorb most of the bending. According to still another exemplary embodiments of the present disclosure, a balloon-catheter tethered capsule can be provided, and according a yet further exemplary embodiment, a structured balloon design can be provided with one or more protuberances, thus enabling imaging of the structures in close contact, e.g., without compressing of the tissue.

  • Patent number: 8083670
    Abstract: The present invention provides an endoscope comprising: an insertion unit which is to be inserted into a body; and a pipeline provided inside the insertion unit for supplying a fluid to a balloon mounted on an outer peripheral surface of the insertion unit, wherein the pipeline has a plurality of openings in an axial direction of the insertion unit on the outer peripheral surface of the insertion unit. Therefore, the endoscope of the present invention can easily fix a balloon and keep airtightness after the fixation, and can raise a degree of freedom of a mounting location of the balloon.

  • Publication number: 20110301417
    Abstract: Apparatus and methods for locating morphological features within a body cavity using a catheter including proximal and distal ends, a transparent balloon carried on the distal end, and an optical imaging assembly carried on the distal end for imaging through the balloon. The balloon includes a channel extending therethrough to a lumen extending through the catheter. A guidewire or other localization member is received in the lumen that is extendable through the channel. During use, the catheter is inserted into a right atrium of a heart, and the balloon is expanded and placed against the wall of the heart to locate the coronary sinus. Sufficient force is applied to clear blood between the surface and the wall and clear the field of view of the imaging assembly. The catheter is manipulated to locate the coronary sinus, whereupon the localization member is advanced into the coronary sinus.

  • Patent number: 8038598
    Abstract: A balloon endoscope device having a shaft with a distal end that allows for blunt dissection is provided. The shaft utilizes a plurality of separately inflatable balloons that alone or together with exterior functional channels (e.g., instrument channels, air channels, water channels, suction channels) circumferentially surround the distal end of the shaft to better position and maneuver the distal end as it advances through tissue planes and once it reaches a target working space or operative site.
