A connector for coupling an enteral feeding solution supply tube to a port of a gastrostomy device, comprising a fluid conduit having an upstream end and a downstream end; and a nozzle housing a first portion of the fluid conduit at the downstream end configured to be connectable to an orifice defined in the port of the gastrostomy device. The nozzle has a proximal end, a distal end and a longitudinal axis extending therebetween. An external diameter of the nozzle at or adjacent the distal end is substantially equal to an external diameter of the nozzle at or adjacent the proximal end. An external surface of the nozzle includes one or more indentations. The invention also relates to a feeding extension set including a connector and an enteral feeding solution supply tube.

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.

The invention relates to a nasogastric tube (100) comprising a nasogastric tubing (102) having first and second ends (102a, 102b), a power supply part (106) located at or adjacent the first end, and a transducer part (104) located at or adjacent the second end for transmitting or receiving an ultrasound based signal. Also disclosed is a positioning system comprising the said nasogastric tube, and a control module comprising an at least one detection portion and a processor.

A gastrojejunostomy tube may comprise a jejunal tube, gastric tube, and a balloon tube. The jejunal tube may comprise a port at a proximal end and an opening at a distal end. The gastric tube may comprise a port at a proximal end and an opening at a distal end. The gastric tube may be operably, fixedly coupled with the jejunal tube to form a tubular portion of the gastrojejunostomy tube. The balloon tube may comprise a port at a proximal end and a balloon at a distal end, and may be sized to dispose the balloon in the stomach of the target patient. The balloon tube may be selectably removable from the tubular portion of the gastrojejunostomy tube such that the tubular portion remains in the target patient and the balloon tube is removed from the target patient and replaced by another balloon tube.

One or more techniques and/or systems are disclosed for a gastrostomy tube having a proximal portion and a distal portion with at least one lumen extending therethrough. The proximal portion includes first, second, and third ports that are each operably coupled to the proximal portion with the first port configured to provide for suction of contents from a patient's stomach, and the third port configured to provide fluid to an inflatable balloon. The distal portion includes a plurality of first openings configured to transport contents to and from the patient's stomach, at least one second opening configured to cooperate with the second port to provide sump-type function, and a curved portion having a gradual bend of approximately 45°-135°. The curved portion directs a distal end of the tube radially outward and away from a longitudinal axis of the tube.

A gastric jejunal (GJ) feeding tube device for GJ feeding of an infant or child is provided. The device comprises a GJ button comprising a GJ button body, a gastric port, a jejunal port, a gastric channel, and a jejunal channel. The device also comprises a multi-lumen tube comprising a multi-lumen tube body, a multi-lumen tube proximal end, and a multi-lumen tube distal end. The device also comprises a jejunal tube comprising a jejunal tube body, a jejunal tube proximal end, a jejunal tube distal end, a spring, and a ring. The spring provides a kink-resistant feature. The ring is positioned at the jejunal tube proximal end. The jejunal tube and the GJ button are operatively connected at the ring and the mating surface by radial compression. The ring has a higher durometer than the jejunal tube body and an outer diameter that does not substantially decrease distally.

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.

A gastrointestinal catheter for insertion into a treatment site in a patient, the treatment site including at least one of a first treatment site and a second treatment site, where the catheter includes at least one of a first and a second treatment member; the proximal portions of the first and second treatment members may be detachably or slidably conjoinable side by side; the distal portions of the first and second treatment members are separate from each other. The distal end of the first treatment member is configured for insertion into the first treatment site; the second treatment member is configured to be placed at a second treatment site. The distal end region of the first treatment member has an anchoring configuration adapted to anchor the distal end region within the first treatment site, the distal end region is further capable of elastically assuming a linear constrained configuration.

A balloon catheter system includes a tube and a dilator detachable from the tube after the tube is inserted into a cavity in the patient. The cavity may be filled with gas or liquid to expand the viscera surrounding the cavity and the guidewire may be inserted using a trochar, for example. The tube includes one or more lumen to expandable balloons that are inflatable by fluid inserted through the lumen and into the balloon or balloons, which are formed by elastic film sealed on opposite ends to the external diameter of the tube. The dilator is held in place during insertion, such as by a stainless steel shaft and a sheath portion of the dilator extending over the end of the tube being inserted into the cavity. A portion of the sheath may extend over and protect the balloon. A retractor net may be used to capture and remove the dilator or the dilator may be designed as a bioabsorbable or digestible material or of a material that passes safely through the digestive tract of a patient.

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.
