A system for feeding and evacuation has a feeding tube in place into a subject's stomach cavity, having a Luer-Lock compatible female connector on an outboard end, a feed source, a unique Lopez valve having a conventional connector on one end and a male Luer-Lock connector on the other end in place of the conventional tapered connector, a suction tube coupled to a suction source, the suction tube having a connector compatible with the conventional connector of the conventional Lopez valve on an end away from the suction source. With the feeding tube connected to the feed source, nutrients are supplied to the subject through the feeding tube, and with the feed source disconnected, the body of the unique Lopez valve connected to the feed tube by the male Luer-Lock extension and to the suction tube, the subject's stomach cavity is exposed to suction controlled by the conventional Lopez valve.

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.

Disclosed is a percutaneous transabdominal port that provides access to a hollow visceral organ. The percutaneous transabdominal port is hollow and has a channel connecting the external surface of the abdomen to the inside of an organ. A catheter or other instrument may pass through this channel into the organ. The percutaneous transabdominal port has a hollow tube which spans an abdominal wall tract, an internal retainer to prevent unintended removal, and an external retainer to prevent withdrawal into the body. If the internal retainer does not rely on inflation, the hollow tube may be cut to length. An optional seal prevents fluid leakage while permitting passage of catheters or instruments. An optional closure cap is described. A method of inserting, utilizing, and removing the percutaneous transabdominal port is described.

An in-scale display device is provided. The in-scale display device includes at least one flexible electronic display screen that is configured to display at least one reference image in-scale with a subject. A medical device position guidance system including the in-scale display device and an invasive medical device system, and a method of using the medical device position guidance system, are also provided.

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 system for feeding and evacuation has a feeding tube in place into a subject's stomach cavity, having a Luer-Lock compatible female connector on an outboard end, a feed source, a unique Lopez valve having a conventional connector on one end and a male Luer-Lock connector on the other end in place of the conventional tapered connector, a suction tube coupled to a suction source, the suction tube having a connector compatible with the conventional connector of the conventional Lopez valve on an end away from the suction source. With the feeding tube connected to the feed source, nutrients are supplied to the subject through the feeding tube, and with the feed source disconnected, the body of the unique Lopez valve connected to the feed tube by the male Luer-Lock extension and to the suction tube, the subject's stomach cavity is exposed to suction controlled by the conventional Lopez valve.

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.

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.
