| 20110275990 | BALLOON CATHETER SYSTEM AND METHODS OF USE THEREOF - A catheter including an outer conduit and an inner conduit movably disposed therein. The distal tip of the inner conduit extends beyond the distal tip of the outer conduit. An inflatable balloon has a first margin attached to the distal tip of the outer conduit, and a second margin attached to the portion of the inner conduit extending beyond the distal tip of the outer conduit. The balloon includes a middle portion, an inflatable distal side portion having at least one tapering part and an inflatable proximal side portion having at least one tapering portion. The length of proximal side portion is equal to or larger than the length of the middle portion. The distal end portion of the balloon is capable of intussuscepting upon proximal movement of the inner conduit within the outer conduit. The catheter includes an inflation/deflation port for introducing and removal of inflating fluid. | 11-10-2011 |
| 20130060234 | INTUSSUSCEPTING BALLOON CATHETER AND METHODS FOR CONSTRUCTING AND USING THEREOF - A catheter including an outer conduit and an inner conduit movably disposed therein. The inner conduit includes at least one movable part. The proximal end of the inner conduit is angled piercing the wall of the outer conduit. The catheter includes an inflatable intussusceptable balloon having a proximal margin attached to the distal tip of the outer conduit and a distal margin attached to a portion of the inner conduit extending beyond the distal tip of the outer conduit. The diameter of a first portion of the balloon is larger than the diameter of other portions thereof. The catheter includes means for axially moving the inner conduit within the outer conduit, means for introducing expansion fluid into the balloon and means for permitting axial movement of the inner conduit within the outer conduit, unhindered by the passage of the angled proximal part of the inner conduit through the outer conduit. | 03-07-2013 |
| 20140188080 | NASOGASTRIC TUBE - A system comprising: a nasogastric tube comprising: (a) a main lumen having one or more proximal connectors for connecting to a source of substances or pressure; (b) at least four vacuum lumens peripherally surrounding said main lumen; and (c) at least four suction ports for sealingly drawing an inner wall of an esophagus thereagainst, each of said at least four suction ports associated with a different one of said at least four vacuum lumens, wherein said at least four suction ports are distributed between at least two different locations along a longitudinal axis of said nasogastric tube. | 07-03-2014 |
| 20150174013 | NASOGASTRIC TUBE WITH CAMERA - A system comprising: a nasogastric tube comprising: (a) a main lumen having one or more proximal connectors for connecting to a source of substances or pressure, (b) at least four vacuum lumens peripherally surrounding said main lumen, (c) at least four suction ports for sealingly drawing an inner wall of an esophagus thereagainst, each of said at least four suction ports associated with a different one of said four vacuum lumens, wherein said at least four suction ports are distributed between at least two different locations along a longitudinal axis of said nasogastric tube; and an imaging system for capturing and rendering one or more images of an area accessible by said tube, said imaging system comprising: (d) a camera disposed at a distal end of said nasogastric tube, for capturing said images; (e) an illuminator disposed at said distal end of said nasogastric tube, and (f) a processing unit provided at a proximal end of said nasogastric tube, that is configured to receive and process said captured images, render said processed images on a display screen, and provide a camera control signal to control said camera and a light control signal to control said illuminator. | 06-25-2015 |
