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.

An adapter is provided for connecting a container of flowable material, such as enteral feed formula in a laminated paper container, to a feeding tube to enable bolus feeding. The adapter can transfer the flowable material from the container by piercing the container and/or a cover of the container. The adapter can form a fluid-tight friction seal on the container. In some embodiments, the adapter has a reusable tube vent long enough to be positioned in the air gap of the container when the container is inverted by a user.

A gastric drainage device includes a tube with a drainage lumen and a hub to receive an inflation device. The tube includes an intragastric portion having a set of holes to permit gastrointestinal contents to pass from a stomach cavity into the drainage lumen. The gastric drainage device includes a bolster with a cylindrical port to receive the tube and a disc to hold the tube in place on a skin side of a gastrostomy site. The gastric drainage device includes a balloon formed around the intragastric portion of the tube, wherein the balloon and the intragastric portion of the tube may be passed through the gastrostomy site into the stomach cavity while the balloon is deflated. Accordingly, the balloon is inflatable within the stomach cavity using the inflation device to secure the gastric drainage device at the gastrostomy site while the gastrointestinal contents are drained from the stomach cavity.

A method for creating a tract for percutaneous endoscopic guided gastrointestinal tube creation including the steps of providing a puncture wire having a sharp tissue penetrating tip shielded in a sheath, the puncture wire slidable within the sheath and releasably lockingly engaged thereto; inserting the puncture wire and sheath in a first direction through a working channel of an endoscope to exit the channel of the endoscope, then releasing the puncture wire from the sheath and advancing the puncture wire from the sheath while visualizing via the endoscope the position of the puncture wire, and further advancing the puncture wire through the visceral wall and then the abdominal wall of a patient. Subsequent methods to position a percutaneous gastrointestinal catheter after initial wire puncture are described.

The present disclosure provides a securement assembly for an enteral access device or vesical access device (“access device”). The securement assembly includes a base and a lid. The base is generally configured to support an external port of the access device and the lid is pivotably coupled to the base. The base comprises a border rim and a central portion, wherein the border rim is configured to engage a skin surface of a patient around a stoma and the central portion is configured to engage the external port of the access device. The central portion may comprise opposing side arms defining an aperture through which a tube of the access device extends.

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.

[Problem] To provide an economic suction adaptor that is capable of suctioning a highly viscous enteral nutrient to a gastric fistula catheter syringe without the intake of air.

[Solution] The number of people having meals of highly viscous enteral nutrients such as blended diets through a gastric fistula catheter is increasing among pediatric patients who need long-term intubation nutrients, and among elderly people who have trouble with oral intake. Suctioning a blended diet on a dish with a syringe alone is undesirable because air is introduced. The suction adaptor of the present invention is used by being connected to the syringe, wherein a suction tube having, on an upper portion thereof, a connection part connected to a nozzle of the syringe is formed in the middle of a bowl-shaped suction pad which is an elastic body.

A syringe includes a barrel, a plunger, and a sealing member creating a seal between the plunger and the barrel. The barrel includes a first portion with a first inner diameter and a second portion with a second inner diameter that is larger than the first inner diameter. The sealing member engages the first portion of the barrel to give rise to a first contact pressure when the barrel is filled with product. The first contact pressure is sufficient to maintain a gas-tight seal over the expected temperature ranges −25° C. to 40° C. A first force is applied to the plunger to overcome the first contact pressure and move the plunger out of the first portion and into the second portion to dispense product. The sealing member engages the second portion of the barrel to give rise to a second contact pressure that is lower than the first contact pressure. A second force lower than the first force is sufficient to overcome the second contact pressure and move the plunger in the second portion to continue dispensing product. The syringe may include a restraining element for accommodating expansion of the product during freezing.

The stomach tube is a transparent conduit in the form of a plastic tube which is equipped with an optical fibre with illuminating external surface. Its internal end is placed in the section of the stomach tube for insertion in the patient's stomach. An external end for connection with a light source is provided outside the stomach tube in the section of the stomach tube remaining outside the patient's body. The conduit of the stomach tube in its interior includes a first channel which is a transport channel, and a second channel in which the optical fibre is located. The stomach tube is intended for use in bariatric surgery procedures, and in particular in the sleeve gastrectomy procedure.
