The present invention is an enteral nutrition gastrostomy access device. A permanent or semi-permanent stoma liner is adjustably positioned within a stoma channel extending through a patient's abdominal and stomach walls. The stoma liner is characterized by an adjustable bladder capable of applying variable torsional force to one or more pinch points along the interface between the stoma liner and the stoma. The stoma liner is configured to receive a plug with a central threaded channel, into which a cap or enteral feeding device may be wholly or partially inserted. The central threaded channel is characterized by requiring application of a linear push force to apply but requiring application of both a linear pull force and a torsional force to remove.

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.

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.

The present disclosure provides a device that includes a tube having a first end and a second end. The device also includes a stopper coupled to a surface of the tube adjacent to the second end of the tube. The stopper is configured to extend radially from the surface of the tube. The device also includes a first rib coupled to the surface of the tube. The device also includes a second rib coupled to the surface of the tube. The first rib and the second rib are positioned opposite one another on the surface of the tube between the first end of the tube and the stopper.

Gastric and intestinal feeding tube devices and methods can be enhanced to provide better patient outcomes. For example, this document provides gastric and intestinal feeding tube devices that include an external bumper with pressure sensors and pressure indicators that facilitate usage of the feeding tube devices within an appropriate range of skin surface pressure. This document also provides external bumpers with deflectable elements that facilitate the application of a controlled amount of force between the external bumpers and the skin surface.

Medical device designs for enteral nutrition that inhibit the relative motion of one device member to another device member are herein disclosed. The gastric and/or intestinal feeding tube shaft is disposed of teeth, furrows, ridges, indentions, tabs, or corrugations that operate with an external retaining member. Alternative embodiments utilize an external retaining member with a collet fitting that applies pressure against the gastric and/or intestinal feeding tube shaft. The assemblies prevent the relative motion of the internal retention member relative to the external retaining member and assist in maintaining the internal retention member against the gastric wall.

A feeding tube and method for introducing a feeding tube within the gastrointestinal tract of a patient, whereby the feeding tube is introduced by using a variation of the Ponsky “pull” method of feeding tube placement. The feeding tube comprises an elongate shaft having a distal end and proximal end. The feeding tube also comprises a coupling structure for coupling the feeding tube to a pull wire, the coupling structure being internal to and proximal of the distal end of the feeding tube shaft. The coupling structure is configured to engage an outwardly biased anchor member affixed to the end of the pull wire. The feeding tube is introduced within the patient by attaching the anchor member of the previously placed pull wire to the coupling structure of the feeding tube, and then pulling the pull wire so as to pull the feeding tube into and through the gastrointestinal tract of the patient.
