There is provided herein a system and a method for an insertion device positioning guidance system comprising: an electromagnetic field generator configured to generate an electromagnetic field covering a treatment area; a plate sensor configured to be positioned within the treatment area in a location defining an orientation of a subject; a reference sensor configured to be positioned, within the treatment area, on the subject's torso, the reference sensor is configured to define a reference coordinate system representing the position and orientation of the subject's torso relative to said field generator; a registration sensor configured to mark at least a first and a second anatomic locations relative to the reference coordinate system; and a processor configured to operate said field generator, read signals obtained from said the plate sensor, said reference sensor and said registration sensor, calculate a position and orientation thereof relative to said field generator, generate a 3D anatomic map representing the torso of the subject and the first and second anatomic locations, said processor is further configured to facilitate visualization on the 3D anatomic map of a position, orientation and/or path of a tip sensor, located in a distal tip section of the insertion device, with respect to the first and second anatomic locations, independent of the subject's movement and independent of deviations in the position and/or orientation of said field generator, thus determination of a successful medical procedure is facilitated.

Assembly of devices, and a kit, for use in replacement gastrostomy tube therapy, consisting of: 1) a Replacement Gastrostomy Tube status device comprising an evaluation module able to trigger an alarm that indicates the inflation status of a retention balloon; 2) a temporary distal “tip” structure for use in centering the Replacement Gastrostomy Tubes in vivo; and 3) a gastrostomy tube comprising a mesh latticework structure to increase the structural integrity of the Replacement Gastrostomy Tubes; and/or a pH sensor measuring acidity of fluid at distal tube opening. The module/unit comprises a battery powered, visual light, auditory signal or network-connected communication to convey the retention balloon's inflation status. The temporary distal “tip” structure includes various tapers, with minimal distal area, to facilitate placement of the Replacement Gastrostomy Tube via a self-centering function, in which the tip is chemically or mechanically released into a digestive tract, or withdrawn externally after a Replacement Gastrostomy Tube is positioned in vivo.

A method of operating an enteral feeding pump to deliver fluid through a pump set, the method comprising determining with a controller of the enteral feeding pump if an occlusion exists in the pump set based on the controller monitoring a sensor signal from a sensor indicative of a rotational position of a rotor of the pump during operation of a motor of the pump to rotate the rotor at a reduced output less than a feeding output for rotating the rotor to produce fluid flow in the pump set during a feeding cycle, the motor operating at the reduced output for a shorter period of time than the feeding output.

Disclosed is an active inserted gastric tube with an intra-body communication function, including a tube body, a pulse module, an intra-body communication module and a control module. The pulse module is arranged at a front end of the tube body, and is configured to generate a pulse signal. the intra-body communication module is configured to receive the pulse signal generated by the pulse module and transmit the pulse signal to the control module. The control module is configured to analyze the received pulse signal. In this way, the pulse signal is generated by the pulse module, and the gastric tube is inserted into the esophagus through the tube body. The pulse signal is transmitted through a human body to realize an intra-body communication. The control module analyzes the pulse signal transmitted through the human body, so as to identify whether the tube body is inserted into the esophagus or trachea.

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 medical device position notification system including a negative pressure device. The medical device is configured to be inserted into an orifice of the patient. The negative pressure device provides information related to the position of the medical device in the patient's body and communicates the information in real-time. The negative pressure device may also be coupled to a sensor, processor, and display device and indicates the position of the medical device in the patient's body in real-time.

A tubing assembly for use with electronic catheter guidance systems is provided and includes a catheter and an acoustic sensor. The catheter extends in a longitudinal direction and has a proximal end and a distal end that define a lumen therebetween. Further, the catheter is configured for placement within a patient's digestive tract. The acoustic sensor can be located within the lumen of the catheter or in a sampling chamber connected to the catheter. The acoustic sensor can communicate with a processor to deliver sound data to a display device. The appearance of random spikes on a frequency versus time spectrogram can indicate placement of the catheter in the digestive tract, while a rhythmic/repetitive pattern on a frequency versus time spectrogram can indicate placement of the catheter in the respiratory tract. A catheter guidance system and method for accurately placing a catheter in the digestive tract are also provided.
