A medical device includes an endoscope head which is designed to be detachably connected to endoscope tubes. The endoscope head has a longitudinal channel between a proximal end and a distal end of the endoscope head for receiving an endoscope tube. At least one measuring channel is arranged in the endoscope head. The measuring channel has at least one inner connection opening, which is connected to the longitudinal channel, and at least one outer connection opening, which is arranged on the outside of the endoscope head. The outer connection opening can be connected to at least one measuring channel in a measurement adapter which can be detachably coupled to the endoscope head.

Devices systems and methods are disclosed for removing secretions from the lumen of a functional assessment catheter for the lungs. The system comprises a flushing unit configured to deliver a clearing fluid to the lumen of the pulmonary catheter to remove debris, secretions, or moisture from the lumen or sensors.

A non-invasive ventilation system may include at least one outer tube with a proximal lateral end of the outer tube adapted to extend to a side of a nose. The at least one outer tube may also include a throat section. At least one coupler may be located at a distal section of the outer tube for impinging at least one nostril and positioning the at least one outer tube relative to the at least one nostril. At least one jet nozzle may be positioned within the outer tube at the proximal lateral end and in fluid communication with a pressurized gas supply. At least one opening in the distal section may be adapted to be in fluid communication with the nostril. At least one aperture in the at least one outer tube may be in fluid communication with ambient air. The at least one aperture may be in proximity to the at least one jet nozzle.

The invention relates to a tracheostoma spacer with a tubular support framework. The support framework can be expand from an initial state to a supporting state of increased diameter and has a fixing element at the ends. The tracheostoma spacer is intended for use as a spacer in a tracheostoma (an opening in the trachea). The invention further relates to a device for inserting a tracheostoma spacer into a tracheostoma with a cutting instrument in the form of a trocar, the tracheostoma spacer being able to be positioned on the shaft of said trocar. A cover sleeve is also provided which can be moved on the shaft over a tracheostoma spacer positioned there.

Improved methods and devices are described for sensing the respiration pattern of a patient and controlling ventilator functions, particularly for use in an open ventilation system. An apparatus for sensing respiration and synchronizing a ventilator to the respiration of a patient is described. The apparatus may include a plurality of thermal breath sensors. At least one of the plurality of thermal breath sensors may be a heated thermal breath sensor.

Methods, systems and devices are described for providing mechanical ventilation support of a patient using an open airway patient interface. The system includes gas delivery circuit and patient interface configurations to optimize performance and efficiency of the ventilation system. A ventilation system may include a ventilator for supplying ventilation gas. A patient interface may include distal end in communication with a patient airway, a proximal end in communication with ambient air, and an airflow channel between the distal end and the proximal end. A gas delivery circuit may be adapted to attach to the patient interface without occluding the patient interface to allow ambient air to flow from outside the patient interface to the patient airway. The ventilation gas may entrain air from ambient and from the patient airway.

Spontaneous respiration is detected by sensors. An additional amount of oxygen is administered to the lungs via a jet gas current at the end of an inhalation procedure. Breathing volume, absorption of oxygen during inhalation, and clearance of carbon dioxide during exhalation are improved. If required, the exhalation procedure of the patient can be arrested or slowed by a countercurrent to avoid a collapse of the respiration paths. An apparatus including an oxygen pump can be connected to an oxygen source and includes a tracheal prosthesis that can be connected via a catheter. The respiration detections sensors are connected to a control unit for activating the oxygen pump. The tracheal prosthesis includes a tubular support body with a connection for the catheter, and the sensors are associated with the support body. The tracheal prosthesis and jet catheter are dimensioned so the patient can freely breathe and speak without restriction.

Minimally invasive methods, systems and devices are provided for assessing collateral ventilation in the lungs. In particular, collateral ventilation of a target compartment within a lung of a patient is assessed by advancement of a catheter through the tracheobronchial tree to a feeding airway of the target compartment. The feeding airway is occluded by the catheter and the opening and closing of a one-way valve coupled with the catheter is observed. If the valve ceases opening and closing over time, this may indicate that significant collateral ventilation into the target compartment is absent. If the valve continues to open and close over time, significant collateral ventilation into the compartment may be present. Based on the collateral ventilation assessment, a treatment plan may be generated.

Modes, methods, systems and devices are described for providing assisted ventilation to a patient, including wearable ventilation systems with integral gas supplies, special gas supply features, ventilation catheters and access devices, and breath sensing techniques.

An instrument for implanting an expandable cylindrical vascular prosthesis includes an outer tube and an inner tube which can be displaced relative to one another. The inner tube is longitudinally slotted on the distal end, at least in an area thereof, and ensheathes the stent with this area which includes the longitudinal slot. In order to implant the stent, the outer tube is retracted. The stent then expands with continuous retracting movement of the outer tube and the inner tube is pressed open along the longitudinal slot. Implantation is terminated, when the outer tube is retracted along the entire length of the stent. The implantation is reversible by pushing the outer tube forward, as long as the stent has not yet fully exited the instrument. In this way, the inner tube is constricted together with the stent, and compressed to an initial position.
