Patent number: 9427143Abstract: A self-propelled device for locomotion through a lumen, comprising a set of serially arranged inflatable chambers, adjacent chambers being fluidly connected, and a fluid source attached to one end of the set, such that the chambers inflate sequentially. The chambers are constructed of an elastic material and have a wall thickness and dimensions such that they have a characteristic with a non-monotonous relationship between the inflation pressure within the chamber and the chamber's inflated size. The characteristic is such that after an initial inflation pressure peak, the non-monotonous relationship adopts a negative slope, such that the volume of the chamber increases more rapidly than the volume of fluid flowing into it, and the inflation pressure of the chamber falls. This effect causes the chamber to inflate and anchor rapidly, while essentially slowing down the inflation of the succeeding chamber until inflation of the first is complete.Type: GrantFiled: February 10, 2008Date of Patent: August 30, 2016Assignee: TECHNION RESEARCH AND DEVELOPMENT FOUNDATION LTD.Inventors: Daniel Glozman, Noam Hassidov, Moshe Shoham

Publication number: 20150367101Abstract: A self-propelled device for locomotion through a lumen, comprising a set of serially arranged inflatable chambers, the end ones of which expand at least radially when inflated. Connecting passages provide fluid communication between each pair of adjacent chambers. A fluid source is attached to one of the end chambers. The connecting passages are such that the fluid inflates the chambers in a sequence, beginning with the chamber closest to the source, and ending with the chamber furthest from the source. The same sequence occurs when the chambers deflate, beginning with the chamber closest to the source, and ending with the chamber furthest from the source. The fluid source can either be a fluid supply tube, extending to a supply outside the lumen, or it can be built-in and carried by the device. The device can crawl either along the lumen wall or on an inserted guide wire.Type: ApplicationFiled: June 22, 2015Publication date: December 24, 2015Inventors: Moshe Shoham, Noam Hassidov, Daniel Glozman

Patent number: 8398540Abstract: A disposable endoscope body having an enclosure in its distal end for a non-disposable element, such as a video camera head. Because of its complexity and sensitivity, the camera head is non-disposable and cannot be sterilized. The camera head is sealed in the endoscope body, such that it does not contaminate the patient during the procedure. Sealing is achieved using an end cap. After use, the camera is withdrawn from the proximal end of the endoscope, which, being near to or within the workstation, has not been inserted into the subject and should be free of patient contamination. Passage of the camera out through the proximal end therefore avoids contamination by the patient, such that it can be used again without need for sterilization. A dispensing kit is described, for supplying the sterile endoscope body and for installing and sealing the camera with a minimum of manual intervention.Type: GrantFiled: May 11, 2008Date of Patent: March 19, 2013Assignee: Technion Research & Development Foundation Ltd.Inventors: Noam Hassidov, Daniel Glozman, Moshe Shoham
