A connector for coupling to a base of an indwelling device equipped with a circular hub having a radius, a top surface, a side surface, and a circumferential recess defined in the side surface. The connector has a resilient assembly including a plurality of release buttons extending from the resilient assembly and may include a conduit defining a fluid pathway through the connector. Each release button has a finger contact zone and a catch. The catch is configured to releasably engage the circumferential recess. The connector is coupled by positioning the connector on the circular hub and depressing the connector until the catches engage the circumferential recess such that the connector is configured to rotate completely about the circular hub. The connector is decoupled from the hub by pressing the release buttons to reversibly displace the respective catches radially to disengage from the circumferential recess.

A stoma dilation device that includes a tubular support defining a continuous pathway through the device; an inflatable dilation balloon located on the tubular support, the inflatable dilation balloon including a dilation region forming a first portion of the device and a retention region forming a second portion of the device; and a balloon inflation lumen. The retention region of the balloon is configured to have a diameter upon full, unrestrained inflation that is greater than the diameter of the dilation region.

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.

Disclosed is a system and method for the placement of elongate medical members within a patients body using coaptive ultrasound. In a particularly preferred embodiment, a flexible tube includes a first balloon at a distal end of the tube, and a second balloon at the distal end of the tube and positioned within the first balloon. The first and second balloons are inflatable to form one or more echogenic windows between them, which echogenic window may be detected from within a patient's body by an ultrasound probe that is external to the patient's body. Detection of such echogenic window is used to identify an acceptable location on the patient's body at which to insert a guidewire configured to receive an elongate medical member without damage to surrounding patient tissues or organs.

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.

Devices for inducing satiety in enterally fed patients are provided. In one aspect, an enteral feeding device is provided that includes a catheter tube and an expandable bladder secured to a distal end of the catheter tube. The expandable bladder is positionable within a body lumen of a patient for receiving and dispensing nutrients to the patient. In another aspect, a satiety-inducing device for continuously dispensing nutrients to a patient is provided that includes an enteral feeding tube and an expandable bladder secured to the feeding tube near a distal end of the feeding tube such that the expandable bladder is positionable within a body lumen of the patient. The expandable bladder expands upon receipt of nutrients to occupy a volume of the body lumen and contracts as nutrients are continuously dispensed to the patient.

An improved feeding catheter is provided for feeding/recycling chyme to a distal stoma. The improved catheter includes a hollow tube having an end for insertion into stoma, and a second end adapted to be connected to a fluid source. The first end includes a retention feature comprising a plurality of ribs extending outwardly and longitudinally away from the tube and terminating at a nose junction. Web walls extend between at least one pair of adjacent ribs and the ribs further define a side facing opening configured for fluid to exit into the gastrointestinal tract. Further the retention feature can be moved between a relaxed condition and a stretched condition for insertion through the distal opening, wherein the maximum width of the retention feature in the stretched condition is less than the maximum width of the retention feature in the relaxed condition.

One or more techniques and/or systems are disclosed for a gastrojejunostomy tube (G-J tube) with a replaceable balloon portion. An example G-J tube can comprise a connection point that is appropriately disposed distally from the balloon portion. The connection can be used to detach a proximal portion from a distal portion of the G-J tube; and a replacement proximal portion can be attached, and the G-J tube can be moved to the desired location. The example G-J tube can comprise a jejunal tube, a gastric tube, and a balloon tube, respectively sized to dispose the distal opening in an appropriate location in the target patient. The proximal portion can comprise at least the balloon tube, the port of the gastric tube, and the port of the jejunal tube.

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.

A detachable dilator with an extraction device has a detachable dilator tip with a hole and an extraction device having a bead too large for passing through the hole and a string extending from the bead through the dilator tip. The string has a retrieval portion for coupling with a tool extending through an endoscope. For example, the retrieval portion may be a loop attached to the bead by the string. For example, the loop may be formed by knotting the string.
