A catheter having a selectively inflatable external balloon and an internal balloon, where the internal balloon is operable as a valve to control fluid flow through a channel.

A device that is inserted through the abdominal wall and into the digestive tract of a human is disclosed. The device may be placed through a method such as percutaneous endoscopic gastrostomy (PEG). The device includes a gastrostomy style structure that provides fluid communication with the external environment of the patient with the internal contents of the stomach. The device is produced with a series of slotted collection channels that preferentially, when connected to a source of negative relative pressure, directs a significant volume of the high calorie fluidic components of the chyme out of the digestive tract, preventing exposure to the absorptive tissues of the digestive tract when simple sugars and carbohydrates are consumed.

Connector assembly (FIG. 4a) includes a shell (210), a connector body (230), and a plug (250). The shell (210) has a sidewall (212) defining an interior, a first shell end having a first opening (214) defined therein, and a second shell end having a second opening (216) defined therein, each of the first (214) and second openings (216) in communication with the interior to receive percutaneous tubing therethrough, the shell (210) further having an engagement portion. The connector body (230) has a first body end (234) and a second body end (236) with a tube lumen defined therethrough, the first body end (234) having a connector tip (237), the connector body (230) having an engaging portion to engage the engagement portion of the shell (210). The plug (250) has a first plug end and a second plug end with a fluid lumen defined therethrough, the first plug end having a plug tip (257) extending therefrom.

A device, system, kit, and method for managing the passage of fluid through an opening in the body of a patient that includes a fluid-containment receptacle including a collapsible sidewall, the fluid-containment receptacle having a first receptacle opening and a second receptacle opening positioned at opposite ends of the sidewall, the fluid-containment receptacle. The device also including a first flange extending radially outward from the sidewall and positioned at or adjacent to the first receptacle opening and a second flange extending radially outward from the sidewall at or adjacent to the second receptacle opening. The device is configured to be applied to the opening in the body of the patient such that the first opening and the first flange contact the body of the patient and form a fluid barrier around the opening.

In some embodiments a PEG feeding device includes a tube sized to bridge a channel between a stomach and an outer abdominal surface; an internal bolster, and an external bolster. Optionally the bolsters are connected to the tube. The internal bolster may be sized to resist movement out of the stomach through the stoma. The external bolster may be sized to resist movement into the stoma from the outer abdominal surface. The external bolster may include an underside which extends from the tube in a radial direction between the external bolster and the outer abdominal surface. The underside of the outer bolster may contact the outer abdominal surface at a distance from an external opening of the stoma. Optionally the distance between the internal bolster and the external bolster is adjustable. Optionally an angle between one or both of the bolsters and the tube is adjustable.

Systems, methods, and apparatus for gastric pressure relief, flow regulation, location, gastric residual volume, a placement reminder, bidirectional fluid flow markings, reintroducing gastric material, collection reservoir raising, collection reservoir hanging, a drain port, setting tube length, and vent membranes. A gastric pressure relief system is used in connection with an enteral feeding system, which includes a feeding container, administration tubing and a delivery tube, where the gastric pressure relief system is interposed between the administration tubing and the delivery tube. The gastric pressure relief system includes a collection reservoir with a gas vent to ambient atmosphere, relief tubing secured to both the collection reservoir and a multi-way connector. The multi-way connector joins the administration tubing to the relief tubing and a delivery tube at a point below a patient's stomach, which is designated on a placement reminder apparatus.

There is provided a system for managing reflux during an enteral feeding, comprising: (i) a non-transitory memory having stored thereon a code for execution by at least one hardware processor of a computing device, the code comprising: code for receiving electrical signals outputted by at least one reflux event sensor disposed within a digestive system of a patient; code for determining a gastric reflux event based on an analysis of the electrical signals; code for outputting instructions to pause enteral feeding of the patient by a feeding controller that regulates enteral feeding of the patient using an enteral feeding tube positioned within the digestive system of the patient; and (ii) an evacuation controller that directs back-flow of digestive contents from the digestive system of the patient to an external evacuation reservoir through an evacuation tube.

A gastrostomy or nasogastric tube venting unit has a containment vessel for measuring fluids expelled with gastric gas before, during, after, or independent from feeding. The venting unit is particularly well-suited for pediatric or extremely weak patients who have difficulty producing sufficient pressure to expel gas through a fluid-filled feeding tube, including babies weighing less than 2000 grams. The venting unit includes a handle for suspending from an IV pole, a car or infant seat, stroller, a coat hook, or other support structures that might be used for travel. The containment vessel has a splash guard in the form of mesh material or screen covering or molded within the upper opening of the vessel, and can be capped temporarily for ease of transportation. The cap can be reopened when the patient is secured in a car seat or other means for travel, so that venting can resume. The splash-guard screen prevents spilling, spraying or splashing of liquids when gastric contents are explosively expelled along with gas.

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.

There is provided herein a system and a method for guiding insertion of a gastroenteral tube including: an electromagnetic field generator configured to generate an electromagnetic field covering a treatment area; wherein said electromagnetic field generator is external to the patient; a registration sensor configured to mark anatomic locations on the patient's torso; a gastroenteral tube comprising a tip sensor configured to sense its position and/or orientation relative to the electromagnetic field generator; and a processing circuitry configured to: calculate an orientation of the subject relative to the field generator based on the anatomic locations marked by the registration sensor, load a predefined anatomic map representing a torso; aligning the map based on the anatomic locations marked by the registration sensor, and showing on the map a path of the gastroenteral tube insertion; wherein the path is generated according to changes in the strength of the electromagnetic field sensed by the tip sensor's during the insertion of the gastroenteral tube, independent of the subject's movement and independent of deviations in the position and/or orientation of said field generator.
