An anatomical manometry catheter system, comprising a plurality of balloons on the distal end and being configured to be inflatable and/or deflatable. The system includes a connector assembly coaxially aligned with the catheter assembly, the connector assembly being connectable to the proximal end of the catheter. The connector assembly may have a connector interface connected to the proximal end of the catheter. The connector assembly may include a manifold comprising a plurality of channels configured to deliver the pressure transmission medium therethrough toward a respective catheter lumen for inflating one or more balloons. The connector assembly may include a charging mechanism fluidly coupled to the catheter that facilitates inflating each balloon of the plurality of balloons by a common actuating mechanism so as to simultaneously charge each balloon of the plurality of balloons.

Embodiments generally relate to a device for monitoring air pressure in the body of a patient. The device comprises a tube comprising a feeding lumen; a sensor lumen positioned parallel to the feeding lumen; at least one sensor positioned in the sensor lumen; and at least one perforation positioned to expose the at least one sensor to an air pressure within the body of a patient when the device is positioned at least partially in the airway of the patient. The at least one sensor is configured to generate data related to the pressure to which the sensor has been exposed.

An esophageal pressure measurement catheter includes a tube having a proximal end and a distal end. The distal end of the tube is arranged to be inserted into the esophagus of a patient. The tube is provided with at least one pressure sensor for measuring a pressure in the esophagus region of a patient. The tube is provided with at least one inflatable balloon adjacent to the at least one pressure sensor. A distance between an edge of the balloon and the centre of the pressure sensor is less than 20 mm.

Described here are systems and methods for four-dimensional manometry, which can include generating and displaying rendering data that simultaneously depict spacetime variations in impedance, pressure, and esophageal luminal morphology. From these data, bolus tracking and esophageal opening and velocity data can be measured and visualized without the need for additional imaging, thereby reducing a subject's exposure to otherwise necessary ionizing radiation.

Disclosed is an NGT system, the system comprises a nasogastric tube having a diameter and length configured to pass through an esophagus such that the lumen of the NGT maintains fluid communication with a portion of the digestive tract, and a digestive tract sensor operatively associated with the NGT, the digestive tract sensor configured to sense from inside the body and transmit signals in response to one or both of conditions relating to nourishment states of the digestive tract, and positioning of the NGT.

The present disclosure relates to a method for automatic evaluation of a filling volume of an oesophageal balloon catheter (26) inserted into a mechanically ventilated patient (3). The method comprises obtaining (S3-S4) samples of an airway pressure, P.sub.aw, and an oesophageal pressure, P.sub.es, of the patient during an occlusion period in which respiration of the patient is prevented, evaluating (S5) the filling volume of the oesophageal balloon catheter by determining a ratio, ΔP.sub.es/ΔP.sub.aw, between P.sub.es and P.sub.aw from a regression analysis of the P.sub.es and P.sub.aw samples, and communicating (S6) a result of the evaluation to a user.

A nasogastric probe comprises at least one substantially flexible tubular element of elongated shape, provided with at least one main channel communicating with at least one feeding mouth of nutritive substances or the like, which is arranged at a first end stretch of the tubular element itself, and with at least one delivery mouth of nutritive substances or the like, which is arranged at a second end stretch opposed to the first end stretch and intended to be inserted into the patient's stomach passing through the esophagus; and it comprises pressure detecting means inside the esophagus comprising at least one pressure sensor associated with the tubular element and interposed between the feeding mouth and the delivery mouth.

A mechanical ventilation system comprises a plurality of ventilation therapy sub-systems. Each of the ventilation therapy sub-systems is adapted to assist a respiratory function of the patient. The system also comprises a detector of the respiratory drive of the patient, an operator interface receiving one or more control parameters, and a main controller. The main controller assigns a therapeutic contribution to each of the ventilation therapy sub-systems based on the respiratory drive of the patient and on the control parameters. The controller modulates the respiratory drive of a patient by controlling each of the plurality of the ventilation therapy sub-systems according to its assigned therapeutic contribution. Distinct ventilation therapy sub-systems may apply negative pressure on the abdomen of the patient, deliver a non-pressurizing inspiratory flow to the patient, or induce a positive pressure in the airways of the patient.

The present disclose generally relates to systems and methods for active titration of one or more cranial or peripheral nerve stimulators to treat obstructive sleep apnea. The active titration can be accomplished in an automated fashion by a closed-loop process. The closed-loop process can be executed by a computing device that includes a non-transitory memory storing instructions and a processor to execute the instructions to perform operations. The operations can include defining initial parameters for the one or more cranial or peripheral nerve stimulators for a patient; receiving sensor data from sensors associated with the patient based on a stimulation with the one or more cranial or peripheral stimulators programmed according to the initial parameters; and adjusting the initial parameters based on the sensor data.

An apparatus (1) for performing manometric measurements by way of medical devices of the pneumatic type, comprises a processing unit (10), and a pressure transducer (4), which is connected to the unit (10) and adapted to be fluid-dynamically connected to the pneumatic device (3). The processing unit (10) comprises: a setting module (11) configured for setting a reference parameter, which is a function of conformational and/or dimensional features of the device (3); and a measurement module (12) configured for processing the measurements made by the transducer (4), according to the reference parameters (a, b, c) which were set for calculating respective objective pressure values. The medical device (3) of the pneumatic type is fluid-dynamically connectable to a measurement apparatus (1), which is provided with an hollow and compressible active portion (30) and provided with an internal fluid-dynamic path adapted to put into communication the apparatus (1) with the cavity of the active portion (30).
