    Abstract: A self propelled, endoscopic apparatus formed of a flexible, fluid-filled toroid and a motorized or powerable frame The apparatus may be used to advance a variety of accessory devices into generally tubular spaces and environments for medical and non-medical applications. The apparatus when inserted into a tubular space or environment, such as the colon of a patient undergoing a colonoscopy, is advanced by the motion of the toroid. The toroid's surface circulates around itself in a continuous motion from inside its central cavity along its central axis to the outside where its surface travels in the opposite direction until it again rotates into its central cavity. As the device advances within the varying sizes, shapes and contours of body lumens, the toroid compresses and expands to accommodate and navigate the environment. The motion of the toroid can be powered or unpowered and the direction and speed may be controlled.

The instrument includes a parallel motion mechanism that changes the position of a distal end of the surgical instrument without changing the orientation of the distal end. An image capture component is at the distal end of the guide tube, and a joint allows the image capture component to move while the intermediate position remains stationary. The configuration allows a cross section of the guide tube to be oblong. In some aspects, a joint for the image capture component is placed between exit ports for surgical instruments, which allows the guide tube cross section to be further reduced.

    Abstract: The present disclosure relates to calibration target devices, assemblies and methods for use with imaging systems, such as a stereoscopic endoscope. A calibration assembly includes: a target surface extends in three dimensions with calibration markers and a body with an interface that engages an endoscope so the markers are within the field of view. A first calibration marker extends along a first plane of the target surface and a second marker extends along a second plane of the target surface. The planes are different and asymmetric relative to the field of view as seen through the endoscope. Three-dimensional targets, in particular, enable endoscopic calibration using a single image (or pair of images for a stereoscopic endoscope) to reduce the calibration process complexity, calibration time and chance of error as well as allow the efficient calibration of cameras at different focus positions.

In various embodiments, the surgical instrument may comprise a hollow tip for attachment to a distal end of a tubular member such as an endoscope. In other embodiments, the hollow tip is integrally formed on the distal end of the endoscope. The hollow tip is configured such that when it is brought into contact with the inner layer of tissue in the stomach, the tissue is caused to stretch. A hole-forming device may be passed through the hollow tip to pierce through the stretched inner layer and adjacent outer layers of tissue to form a passageway therethrough for permitting surgical procedures to be performed therethrough. After the surgical procedures are performed through the passageway, the hollow tip is removed from contact with the inner layer of tissue to permit the inner layer of tissue to relax and to cause the holes formed through the inner layer and outer layers of tissue to be offset from each other.

    Abstract: An apparatus applicable for the ligation of internal tissue in a created or natural cavity in animals or in the human body, for example varicose veins in the gullet or a duodenal diverticulum, by means of an elastic band (19) while observing the ligations through an endoscope. The apparatus includes an automatic trigger unit (1) mounted firmly on the handle of the endoscope which can release a number of elastic bands (19) with the aid of a single-stranded trigger cord (11). Only a single elastic band (19) is released for each ligation thereby establishing a one-man-operated apparatus.

  • Patent number: 8795158
    Abstract: An insertion assisting device includes a rotary body in the form of toroid, and a support and drive part for supporting the rotary body in a rotatable manner and rotating it. The support and drive part has an approximately cylindrical supporting member for supporting the rotary body in a rotatable manner. The rotary body is provided with a convex portion for increasing the thickness to improve the strength thereof. A concave portion having a shape corresponding to the shape of the convex portion is formed on a portion of a front end surface of the supporting member, which is made in contact with the convex portion. The concave portion prevents the rotary body from stopping rotating, which may be caused by point contact between the convex portion and the supporting member.

  • Patent number: 8771173
    Abstract: The present invention provides an access device for surgery. The access device includes a guide member and a head member. The guide member and head member define a channel configured to receive and guide a sterile flexible scope with a working channel. The guide member and head member cooperate to extend through a small opening of 2 cm or less to access tissue structures. The head member may include surfaces to separate a pericardium from a surface of the heart, stabilize a beating heart and, with the endoscope, provide visibility for the implantation of a therapeutic such as stem cells to the surface of the heart with improved safety and accuracy. Ranges of other diagnostic, application of therapeutics or biologics, and observational applications may be facilitated by the access device, such as TMR, ablation, echo-probe diagnostics, LAA isolation, observation of the same procedures, etc.

  • Patent number: 8771174
    Abstract: To provide a tool for safely and reliably securing a route for endermically approaching the interior of the body; more specifically, an endoscope-equipped puncture balloon that is designed to allow a balloon that does not immediately burst when punctured by a puncturing needle or the like to be used as a target, and that can be used by installing or inserting an endoscope in a tube holding such balloon. In a thin-walled main body tube 1 equipped with an endoscope-installed section at the rear end, a balloon 2 is disposed on the front surface thereof, and a branch tube 4 communicating with the interior of the balloon 2 in a gas-liquid flow manner is disposed on the main body tube 1, the branch tube 4 having a connector 5 annexed to the rear end thereof; thus it is not until the liquid in the balloon is absorbed without the balloon immediately bursting when punctured by a puncturing needle that a bore can be secured until the balloon is contracted.

  • Patent number: 8758229
    Abstract: Axial visualization systems which utilize axially aligned imaging instruments for visualizing through an imaging hood purged of blood via a transparent fluid are described where an imaging element extending from a support shaft may be aligned within a working lumen defined through a deployment catheter. The imaging element may be positioned distal to the hood in its collapsed state and within the hood in its expanded state. The imaging element may be configured to seat itself securely within the catheter or to angle itself to adjust the viewing angle. Additionally, a disposable visualization sheath having a transparent lens may also be utilized to house an imaging instrument therein.
