Abstract
An enteral feeding device permitting diversion of gastrointestinal fluid from an afferent limb to an efferent limb of gastrointestinal tract in a subject is provided. The device can be used to reduce leakage from around device and thus reduce morbidity associated with such leakage. In certain embodiments the enteral feeding device is a jejunostomy tube (J-tube). Also provided are methods for positioning and using the enteral feeding device. Also provided are kits for positioning and using the enteral feeding device.
Claims20
An enteral feeding device, comprising
- a first tube comprising a wall and a proximal end and a distal end, the first tube defining a first lumen that extends longitudinally through at least a portion of the first tube, the first tube comprising at least one distal opening capable of allowing delivery of nutrients and/or medicaments from within the first lumen into a distal lumen of a gastrointestinal tract of a subject when the enteral feeding device is positioned in the subject;
- a member configured to be inserted into the first lumen such that the member extends across a reversibly closable proximal opening thereby effectively and reversibly closing the reversibly closable proximal opening;
- and
- a second tube, connected to and extending away from the first tube, comprising a proximal end and a distal end, the second tube defining a second lumen that extends longitudinally through at least a portion of the second tube and is in fluid communication with the first lumen via the reversibly closable proximal opening, the second tube comprising at least one distal opening capable of allowing flow of fluid from within a proximal lumen of the gastrointestinal tract of the subject to the at least one distal opening of the first tube via the second lumen and the first lumen when the enteral feeding device is positioned in the subject and the reversibly closable proximal opening is open.
An enteral feeding device, comprising a first tube comprising a wall and a proximal end and a distal end, the first tube defining a first lumen that extends longitudinally through at least a portion of the first tube, the first tube comprising at least one distal opening capable of allowing delivery of liquids from within the first lumen;
- and a second tube, connected to and extending away from the first tube, comprising a proximal end and a distal end, the second tube defining a second lumen that extends longitudinally through at least a portion of the second tube and is in fluid communication with the first lumen via a reversibly closable proximal opening, the second tube comprising at least one distal opening capable of allowing delivery of liquids to the at least one distal opening of the first tube via the second lumen and the first lumen when the reversibly closable proximal opening is open, wherein the proximal end of the first tube is constructed and arranged so as the first lumen is capable of receivably engaging a reservoir, and wherein engagement of the reservoir by the first lumen reversibly closes the reversibly closeable proximal opening, which is a proximal opening of the second lumen.
