A system and a method for an insertion device positioning guidance system comprising: an electromagnetic field generator configured to generate an electromagnetic field covering a treatment area; a plate sensor configured to be positioned within the treatment area in a location defining an orientation of a subject; a reference sensor configured to be positioned, within the treatment area, on the subject's torso, the reference sensor is configured to define a reference coordinate system representing the position and orientation of the subject's torso relative to said field generator; a registration sensor configured to mark at least a first and a second anatomic locations relative to the reference coordinate system; and a processor configured to operate said field generator, read signals obtained from said the plate sensor, said reference sensor and said registration sensor, calculate a position and orientation thereof relative to said field generator, generate a 3D anatomic map representing the torso of the subject and the first and second anatomic locations, said processor is further configured to facilitate visualization on the 3D anatomic map of a position, orientation and/or path of a tip sensor, located in a distal tip section of the insertion device, with respect to the first and second anatomic locations, independent of the subject's movement and independent of deviations in the position and/or orientation of said field generator, thus determination of a successful medical procedure is facilitated.

Insertion device positioning guidance system and method

There is provided herein a system and a method for an insertion device positioning guidance system comprising: an electromagnetic field generator configured to generate an electromagnetic field covering a treatment area; a plate sensor configured to be positioned within the treatment area in a location defining an orientation of a subject; a reference sensor configured to be positioned, within the treatment area, on the subject's torso, the reference sensor is configured to define a reference coordinate system representing the position and orientation of the subject's torso relative to said field generator; a registration sensor configured to mark at least a first and a second anatomic locations relative to the reference coordinate system; and a processor configured to operate said field generator, read signals obtained from said the plate sensor, said reference sensor and said registration sensor, calculate a position and orientation thereof relative to said field generator, generate a 3D anatomic map representing the torso of the subject and the first and second anatomic locations, said processor is further configured to facilitate visualization on the 3D anatomic map of a position, orientation and/or path of a tip sensor, located in a distal tip section of the insertion device, with respect to the first and second anatomic locations, independent of the subject's movement and independent of deviations in the position and/or orientation of said field generator, thus determination of a successful medical procedure is facilitated.

There is provided feeding tubes including an electromagnetic sensor including a sensor body comprising a core positioned at a distal end of the sensor lumen, and a wire extending along the length of the feeding tube, wherein an RF induced heating of the feeding tube in an MRI environment is below 5 degrees.

Feeding tube with electromagnetic sensor

Dual tube assembly for feeding and suction

Sump tube

A nasogastric tube comprising at least one main lumen and at least one vacuum lumen comprising at least one suction port for sealingly drawing an inner wall of an esophagus thereagainst, said at least one suction port has a unique concave structure which substantially prevents tissue damage is provided.

Nasogastric tube

An enteral feeding system including: an enteral feeding tube, a pump configured to draw a liquid from a reservoir to the enteral feeding tube; a switching mechanism associated with at least four vacuum lumens provided with the enteral feeding tube; and a controller configured to automatically control the pump and the switching mechanism wherein controlling the pump and the switching mechanism includes coordinating the operation of the switch with the operation of the pump.

Enteral feeding system with controlled reflux preventive vacuum sealing

A system comprising a nasogastric tube comprising a nasogastric location element, a feeding mechanism, a suction mechanism configured to sealingly draw an inner wall of an esophagus against said nasogastric tube, and a gastric decompression mechanism.

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.

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; 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.
