    摘要： The present invention is a method for accessing the abdominal cavity of a patient in order to perform a medical procedure therein. In one embodiment the method includes the step of inserting a guide wire into the upper gastrointestinal tract, via a gastric opening in the gastric wall and an abdominal opening in the abdominal wall of the patient, the guide wire having a first end that extends from the mouth of the patient, and a second end that extends from the abdominal opening of the patient. The method further includes providing an access device in the form of an elongated sheath having a lumen therethrough, attaching the first end of the guide wire to the distal end of the elongated sheath, and pulling the second end of the guide wire to position the access device into the upper gastrointestinal tract, wherein the distal end of the access device extends into the abdominal cavity while the proximal end of the access device extends out of the mouth of the patient.

    摘要： An endoscope with guiding apparatus is provided. The endoscope has an elongate body with a steerable distal portion, an automatically controlled portion, a flexible and passively manipulated proximal portion, and an externally controlled and manipulatable guiding apparatus. The guiding apparatus may be positioned within the endoscope or may be positioned adjacent to the endoscope. An interlocking device is provided to slidably interlock the guiding apparatus and the endoscope. When the guide is in a flexible state, it can conform to a curve or path defined by the steerable distal portion and the automatically controlled portion. The guide can then be selectively rigidized to assume that curve or path. Once rigidized, the endoscope can be advanced along the guide in a monorail or nullpiggy-backnull fashion so that the flexible proximal portion follows the curve held by the guide until the endoscope reaches a next point of curvature within a body lumen.

    摘要： A method of epidural surgery is provided that improves visibility in the epidural space of a patient for more effectively conducting therapeutic surgery therein. The method includes the steps of distending a portion of the epidural space of a patient by filling the portion of the epidural space with a fluid supplied from a catheter and positioning a portion of an optical scope in the distended portion of the epidural space by inserting the optical scope through the same catheter that supplies the distending fluid to thereby provide a visual image of the epidural space.

    摘要： According to the present invention, a fixing member is integrated with a mouthpiece body through slide grooves and a rotational groove, and this improves the portability. Moreover, a guide tube can easily be fixed to the mouthpiece body only by rotating the fixing member with the rotational groove. Furthermore, an index is formed on the outer peripheral surface of the guide tube. The index is composed of scale lines formed at regular intervals and scale numbers formed at predetermined scale lines. The scale numbers represent the distances from a front end of the guide tube to the scale line, and the distances from a back end of the guide tube to the scale line. The index of the guide tube is used in combination with an index formed on an endoscope insertion part, and this makes it possible to correctly recognize the insertion length of the endoscope insertion part inserted into a body cavity of a subject.

    摘要： The present invention provides methods, apparatus, and systems for accessing and imaging a patients body lumen, particularly a fallopian tube through an ostium, in a minimally or non-invasive manner. The present invention provides simplified ostium access apparatus and procedures which help to avoid the high cost and large size of known systems having redundant optical scopes for use in the uterine and tubal environments. By separating and independently optimizing the illumination optics from the imaging optics, the present ostium access system is able to make use of the optical image guide of a falloposcope in the substantially larger uterine cavity. As a result, fewer physicians may be required to perform such procedures, in many cases reducing the time, complexity, and, particularly, the cost of such procedures.
