Disclosed are laryngeal airway devices for human and veterinary use. The device includes an airway tube having a distal end and a proximal end, the distal end of the airway tube is provided with a pre-formed and non-inflatable peri-pharyngeal bowl, the peri-pharyngeal bowl has a posterior bowl portion having a back dorsal portion and a side wall extending around and depending from the periphery of the back dorsal portion to define an internal space, the peri-pharyngeal bowl further having a resiliently deformable flange extending laterally from the side wall of the back dorsal portion which defines an extended internal space, the resiliently deformable flange having inner and outer surfaces that extend to a circumferential edge.

A system is disclosed for performing an endoscopic surgical procedure in a surgical cavity, which includes a multi-modal gas delivery device including a primary gas circulation pump, a secondary gas circulation pump and an insufflation subunit, and an interface plate adapted and configured to engage with the multi-modal gas delivery device and including a connector and a filter seat corresponding to five different lumens, each of which provides a different functionality.

A medical device comprising an enclosure defining a cavity for containing agent, a lumen for receiving a pressurized gas, and a barrier positioned between the cavity and the lumen, the barrier including at least one opening for storing agent, wherein rotation of the barrier relative to the lumen establishes fluid communication between the at least one opening and the lumen for delivering agent from the at least one opening to the lumen.

There is provided system for monitoring spontaneous breathing of a mechanically ventilated target individual, comprising: a feeding tube for insertion into a distal end of an esophagus of the individual, sensor(s) disposed on the feeding tube at a location such that the sensor(s) is located at the distal end of the esophagus of the individual when the feeding tube is in use, wherein the sensor(s) is positioned for sensing values by contact with the tissue of the esophagus including a lower esophageal sphincter (LES) and/or tissue in proximity to the LES, and code for computing an indication of a frequency band of diaphragm movement of the individual according to an analysis of values sensed by the sensor(s), and for adjustment of parameter(s) of a mechanical ventilator for mechanically ventilating the individual, wherein the instructions for adjustment are computed while the feeding tube is in use.

The disclosure provides a respirator, which includes a ventilation device, configured for providing ventilation airflow to a patient. The respirator further includes a first monitor, configured for monitoring a pressure or a flow velocity with which the ventilation device ventilates the patient, and a second monitor, configured for measuring a pressure change that reflects a self-respiratory effort of the patient. The respirator also includes a processor, configured for identifying an inspiratory trigger moment or an expiratory trigger moment of the patient according to the pressure change that reflects the self-respiratory effort of the patient.

Various embodiments disclosed relate to drug-coated balloon catheters for treating strictures in body lumens and methods of using the same. A drug-coated balloon catheter for delivering a therapeutic agent to a target site of a body lumen stricture includes an elongated balloon having a main diameter. The balloon catheter includes a coating layer overlying an exterior surface of the balloon. The coating layer includes one or more water-soluble additives and an initial drug load of a therapeutic agent.
