    摘要: A catheter introducer system for endoscopy includes a steering section and a propulsion section located near the end of the flexible, tubular catheter that is introduced in a body cavity. The propulsion section is designed to pull the rest of the catheter inside the body cavity, so there is no need to push the catheter along from outside the body. Propulsion may be accomplished by relatively movable gripping pads that selectively apply suction to the tissue. The steering section is designed to point the end of the catheter that is introduced into the body cavity in the desired direction. The catheter can thus be made very flexible in bending, and a larger diameter catheter can be used without discomfort to the patient.

    摘要: A tool for coaxially loading a flexible member into a lumen of a catheter. Typically, the flexible member is a flexible imaging core or similar device. The tool includes a body which has a connector, which connects the body to a hub located on the catheter. A pair of opposed rollers, disposed proximate to the connector, are used to advance the flexible member, through the connector, and into the catheter, which is connected to the connector. The flexible member is advanced by counter rotating the rollers.

    摘要: A self propelling catheter introducer system for exploring a body cavity is disclosed which includes a flexible tubular catheter, a propulsion section and a steering section located near the end of the catheter that is introduced in a body cavity. The propulsion section includes a flexible everting tube designed to push the catheter from inside the body cavity. The catheter can thus be made very flexible in bending, and a larger diameter catheter can be used without discomfort to the patient.

    摘要: Improving upon conventional endoscope patent, the proposed design (Creeping colonoscope) has a new mechanism for movement of the conventional colonoscope in the large intestine. This method of movement, which resembles climbing a ladder, where hands could assist the climbing force of the feet results from consecutive appliance of a pair of sucking arms on the tip of the colonoscope to the adjacent mucosa. The sucking arms adhere to the mucosa by vacuum power provided by an external suction device and pull the mucosa toward the tip of the fiberoptic colonoscope after mucosal adhesion. Successive repetition of this operation not only pulls the mucosa over the colonoscope but also moves the colonoscope tip onward. It should be noted that this mechanism of action is not a substitute of the primary mode of movement of the colonoscope induced by pushing of the shaft. But this minor movement help the colonoscope to pass the flexures more smoothly and with less pushing force that induce pain and discomfort for the patients. Passing the tip beyond the flexure, the endoscopist would be able to perform hooking and shortening (straightening) maneuver more easily and this leads to better transmitting of the pushing force to the tip of the colonoscope. The result is less effort and procedure time on the physicians' end and less pain and discomfort on the patients' end.

    摘要翻译: 改进传统的内窥镜专利,提出的设计(爬行结肠镜)具有传统结肠镜在大肠中运动的新机制。 这种运动方式类似于爬梯,手可以帮助脚的爬升力由结肠镜的尖端上的一对吸臂的连续装置产生于邻近的粘膜。 吸附臂通过由外部抽吸装置提供的真空动力粘附到粘膜上,并且在粘膜粘附后将粘膜拉向光纤结肠镜的尖端。 连续重复这一操作不仅将粘膜拉到结肠镜上,还可以将结肠镜向前移动。 应该注意,这种作用机制不能代替通过推动轴而引起的结肠镜的主要运动模式。 但这种小动作有助于结肠镜更顺利地传递弯曲,并且具有较少的推力,从而引起患者的疼痛和不适。 将尖端穿过弯曲部,内窥镜医生能够更容易地进行钩挂和缩短(矫直)操作,并且这可以更好地将推力传递到结肠镜的尖端。 结果是减少了医生的努力和程序时间,减少了患者的痛苦和不适。

    摘要: A method and apparatus for temporarily immobilizing a local area of tissue. In particular, the present invention provides a method and apparatus for temporarily immobilizing a local area of heart tissue to thereby permit surgery on a coronary vessel in that area without significant deterioration of the pumping function of the beating heart. The local area of heart tissue is immobilized to a degree sufficient to permit minimally invasive or micro-surgery on that area of the heart. The present invention features a suction device to accomplish the immobilization. The suction device is coupled to a source of negative pressure. The suction device has a series of suction ports on one surface. Suction through the device causes suction to be maintained at the ports. The device further is shaped to conform to the surface of the heart. Thus, when the device is placed on the surface of the heart and suction is created, the suction through the ports engages the surface of the heart. The suction device is further fixed or immobilized to a stationary object, such as an operating table or a sternal or rib retractor. Thus, the local area of the heart near the suction device is temporarily fixed or immobilized relative to the stationary object while suction is maintained. In such a fashion, the coronary artery may be immobilized even though the heart itself is still beating so that a bypass graft may be performed. In addition the suction device may be used in either a conventional, open-chest environment or in a minimally-invasive environment, e.g. endoscopic.
