The present invention relates to an imaging apparatus comprising an elongated carrier adapted to be inserted through a proximal opening of a gastrointestinal (GI) tract lumen; a piston head, coupled to a distal portion of the carrier, and configured to: be inflated so as to form and maintain a pressure seal with a wall of the GI tract lumen, and be advanced distally through the GI tract in response to pressure from a fluid pressure source; a distal balloon coupled to the carrier distal to the piston head and configured and operable to be inflated so as to dilate the lumen thereby creating a working space; and a control unit, configured and operable to control simultaneously a pressure level within the piston head and a pressure level within the distal balloon. The control comprises maintaining a constant level of pressure within the piston head thereby maintaining said pressure seal and cyclically modulating the level of pressure within the distal balloon facilitating the distal advancement of the piston head within the GI tract lumen.

System and method for enhanced maneuverability

An apparatus is presented for use with a biologically-compatible-fluid pressure source. The apparatus comprises an elongated carrier defining a fluid passageway and adapted to be inserted through a proximal opening of a body lumen having a main axis and certain diameter; an inflatable balloon assembly having an inflatable part self-deformable between its substantially circular geometric state and multiple elongated geometry states in which cross sectional dimensions of the inflatable balloon part are different in accordance with the diameter of the lumen, and being in fluid communication with said fluid passageway, the cross sectional dimension of the substantially circular geometric state being equal to or greater than said diameter of said body lumen; and at least one sleeve extending from at least one end respectively of said inflatable part of the balloon assembly along a central axis of said inflatable balloon part, said at least one sleeve being by its one end is rigidly coupled to the respective end of the balloon part and having one of the following configurations: (a) being by its other end fixed to the carrier at a certain location and being foldable and extendable in accordance with longitudinal deformation of the inflatable balloon part, and (b) having a fixed length and being by its other end slidable along the carrier in accordance with longitudinal deformation of the inflatable balloon part. Deformation of the inflatable part of the balloon maintains the balloon assembly orientation such that the carrier passing through the balloon assembly substantially coincides with said main axis of said lumen.

Self-centralizing inflatable balloon

The present invention relates to a monitoring system and method for use with a body of a subject. The system comprises a medical device, having a portion thereof configured to be placed inside the subject's body, said portion of the medical device being configured to be propelled by fluid pressure through a body lumen; at least two pressure sensors accommodated remotely from the subject's body at two different spaced-apart positions outside the subject's body and configured and operable to detect pressure at the two spaced-apart remote positions; said at least two pressure sensors being in fluid communication with at least one site inside the subject's body, a relation between the pressure at said at least one site and the pressures at said two spaced-apart remote positions being thereby indicative of the fluid pressure at said at least one site.
