Abstract: A medical device position guidance system includes a plurality of noninvasive external detector devices communicable with an invasive medical device. A magnetic field is used to gather information about the anatomical size and shape of a subject, such as a human. The medical device position guidance system further uses the magnetic field to obtain information about the positioning of the invasive medical device relative to the subject's anatomy. A method of using the medical device position guidance system is also provided.

Abstract: A medical device position guidance system is provided. The system includes at least one reference transmitter and a receiver system configured to receive signals from the at least one reference transmitter. The reference transmitter is configured to maintain a static position on a subject. The system further includes a processor configured to (i) receive signals relating to the location and orientation of each sensor of the receiver system relative to the at least one reference transmitter; and (ii) using the received signals, create an anatomical coordinate system. The system may further include an inserted transmitter configured to be attached to a medical device. The inserted transmitter is adapted to establish the location and orientation of the medical device within the anatomical coordinate system. A method for medical device position guidance is also provided.

Abstract: A configurable pathway deviation indication system for medical device placement includes one or more user-adjustable pathway boundaries and an indication activated upon reaching or breaching of any of the pathway boundaries. The system may include a medical device configured to be inserted into a patient; a location transmitter configured to transmit a signal related to a position of the medical device; and a detector device configured to receive information related to the patient's body and the location transmitter. The system may be operatively coupled to the location transmitter and the at least one detector device. The system may further include a display and a computing system comprising one or more processors and or more non-transitory computer-readable media. The system can display the position of the location transmitter; determine if the position of the location transmitter reaches any pathway boundaries; and provide the indication when the pathway boundary is breached and/or approached.

Abstract: A catheter sensor assembly for use in conjunction with electronic catheter guidance systems is provided and includes a catheter and a 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 digestive tract or respiratory tract of a patient. The sensor includes a carbon dioxide sensor, pressure sensor, or both, and can be located in an air sampling chamber connected to the catheter. The sensor can communicate with a processor to deliver carbon dioxide and/or pressure readings to a display device, which can indicate placement of the catheter in the digestive tract or in the respiratory tract. A catheter guidance system and a method for accurately placing a is also provided.

Abstract: A system, method, and apparatus for administering fluids to body cavities, suctioning or aspirating fluids from body cavities, performing gastric decompression, and containing gastric reflux. An exemplary system includes a Y-connector, a multiple lumen tube, and an anti-reflux valve. The Y-connector comprises a delivery arm, a suction arm, and a convergence arm, all in fluid communication with one another and may be coupled to the multiple lumen tube. The multiple lumen tube includes a first lumen, a second lumen, and a plurality of openings. The anti-reflux valve includes a valve adapted to prevent the fluid from flowing beyond the proximal end of the second lumen.
