A multi lumen gastrointestinal catheter is disclosed. The multi-lumen gastrointestinal catheter has a flexible partition separating a feeding and an aspiration channel. A third smaller inflation channel is positioned within the outside exterior wall at the site of the flexible partition to avoid kinking at the inflation channel site, without need to re-enforce the weakened wall.

Multi-lumen catheter

A gastrointestinal catheter having feeding and suction channels in close proximity. The gastrointestinal catheters may have a controlled leak via a recirculation feature.

Gastrointestinal feeding and aspiration catheter

A method of manufacturing a catheter includes positioning a resilient tube in a vacuum tube. An outer periphery of the resilient tube is sealed to the vacuum tube so a vacuum region can be formed therebetween. A dimension of a channel of the resilient tube is adjustable in response to adjusting the pressure of the atmosphere of the vacuum region. The dimension of the channel is adjusted so that a reinforcement member can be positioned therein.

A decompressing and feeding device for safely feeding in the gastrointestinal tract of a recovering patient continuously aspirates and feeds at a rate commensurate with the ability of the intestines to absorb fluids including nutrient. Air is also aspirated in the process so that neither air nor excess fluids cause distension in the gastrointestinal tract. Digestive juices and nutrients that are aspirated are continuously refed together with unused feeding material into the gastrointestinal tract at a location that more efficiently moves and digests the food. The device may include two aspirate reservoirs to which and from which aspirate is alternatingly and continuously transferred. To provide the continuous and alternating flow, a solenoid valve and timer switch device is provided. Alternatively, a device is provided with a single aspirate reservoir to which and from which aspirate is continuously transferred.

The present invention provides a single lumen gastro-intestinal tube for use in both delivering nutrition into the gastro-intestinal tract and aspirating excess materials from the gastro-intestinal tract. The single lumen tube may be delivered into the gastro-intestinal tract transnasally or surgically. The single lumen tube in accordance with the present invention includes a one-way valve which permits nutrition or other fluids to flow out of the tube and into the gastro-intestinal tract but which closes to prevent materials from being aspirated from the gastro-intestinal tract through the one-way valve. The single lumen tube also includes aspiration pores located proximately from the one-way valve. The aspiration pores perform the aspiration of air and excessive materials from the gastro-intestinal tract. Preferably, the aspiration pores are sized so as to filter any solids present in the gastro-intestinal tract from the aspirated material. A single lumen tube in accordance with the present invention may be used in alternating the delivery of nutritional or other materials to the gastro-intestinal tract and the aspiration of air and excessive material from the gastro-intestinal tract.

Single lumen gastro-intestinal feeding-decompression tubes

In accordance with the present invention, a pump apparatus for use in conjunction with the feeding and aspiration of a patient's gastro-intestinal tract is provided. In accordance with the present invention, an apparatus and method are provided in which the aspiration of excessive material and air from a patient's gastro-intestinal tract proceeds until the flow of aspirate ceases. A flow detector determines when aspirate flow has ceased. Aspirate removed from the gastro-intestinal tract is retained for subsequent return to the patient for absorption to prevent dehydration. After the aspiration is concluded, material aspirated from the intestine and additional nutrition or fluids are introduced into the gastro-intestinal tract for absorption by the intestine. After an optional delay to allow for the absorption of materials by the intestine, the aspiration cycle resumes. This frequent aspiration serves to prevent overfeeding and its associated risks of intestinal distention.

Method and pump apparatus for combined gastro-intestinal feeding and aspiration

A fastener implanting device used to implant a head portion of a 'T' or 'H'-shaped fastener within a body. The device has a needle portion and a grip portion. The needle portion encloses a longitudinally displaceable slide mechanism which is adapted to engage and eject the head portion of a fastener disposed within a slotted, distal end section of the needle. The longitudinal displacement of the slide mechanism is controlled by a mechanism located in the device's grip portion.

Surgical fastener implantation device

A dilator/introducer apparatus incorporating a locking system for preventing the premature longitudinal separation of the first and second halves of a frangible-type introducer.

Dilator/introducer apparatus for percutaneous gastrostomy

A gastrointestinal aspirating and feeding device having at least one feeding orifice and a plurality of aspirating orifices. A removable sleeve is utilized to selectively control the number of operational aspirating orifices.
