The present invention is an inflatable balloon which is enclosed by an expandable cover which becomes increasingly porous/permeable during expansion. The balloon is coated or enclosed with a matrix which contains a pharmaceutically active agent. During expansion of the balloon, the pharmaceutically active agent is released or extruded through the expandable cover into a body cavity such as an artery or vein. The present invention also provides for a method of treating a disease or condition by delivering the inflatable balloon to a particular body cavity.

The apparatus comprises: an intubation tube, an end-expiratory CO.sub.2 catheter, a suction tube, an airbag and an inflatable air tube, wherein the end-expiratory CO.sub.2 catheter partially penetrates the sidewall of the intubation tube, one end of the end-expiratory CO.sub.2 catheter extends beyond an end of the intubation tube, and the other end is connected to an end-expiratory CO.sub.2 sensor, the suction tube partially penetrates a sidewall of the intubation tube, one end of the liquid suction tube extends beyond an end of the intubation tube, the other end is connected to an air pump, the airbag sleeves the outer wall of the intubation tube, the inflatable air tube partially penetrates the sidewall of the intubation tube, one end thereof is connected to the airbag, and the other end is connected to the air supply device.

Systems and methods for reducing pathogens near an implant are discussed. In some cases, the methods include reducing contaminants in a portion of a patient that has an implant and that is disposed interior to a closed surface of skin of the patient. The method can further include placing a conduit in the closed surface of skin and flowing an antimicrobial fluid into that portion of the patient to contact the antimicrobial fluid with a surface of the implant and tissue adjacent to the implant. In some cases, the antimicrobial fluid is then removed from the portion of the patient having the implant. As part of this method, biofilm near the implant can be mechanically, ultrasonically, electrically, chemically, enzymatically, or otherwise disrupted. Other implementations are described.

A method of using nanoparticle (NP) spray to treat an infection in the respiratory system and far infrared radiation (FIR) to treat inflammation. The method uses a spray probe inserted into the airway of a patient to apply mSiO.sub.2 and FIR to a target site in the upper respiratory tract. FIR applied may be in the 3-10 μm range. The mSiO.sub.2 spray kills any organisms, including COVID-19 and FIR reduces inflammation resulting from infection. The treatment may be applied to intubated or spontaneously breathing patients and via the oral or nasal passages.

Endotracheal devices and methods of using endotracheal devices are provided. The devices include a first elongated conduit having an internal dimension, a second elongated conduit having an external dimension less than the internal dimension of the first conduit, and a manipulation rod operatively mounted to the second conduit, where the manipulation rod allows an operator to move the second conduit within the first conduit. The manipulation rod may be used translate and/or rotate the second conduit within the first conduit. The first and second elongated conduits may be provided with inflatable cuffs to minimize the passage of fluids. Though aspects of the invention may be uniquely adapted for insertion through the trachea and into a bronchus, aspects of the invention may be used for other bodily passages.

A device for introducing material into a body cavity is shown. The device includes a catheter with a distal tip. A first lumen extends through the catheter. The catheter is configured to faun a mist from liquid passed through the first lumen, for example including a misting nozzle in fluid communication with the first lumen and configured to provide a mist from a flow of liquid through the first lumen. An inflatable balloon may be included on the catheter to allow the user to isolate the portion of the body in which the material is introduced. Additional described features can provide for controlled deflection of a distal region of the catheter, guidewire or guide loop tool lumens, misting nozzles on the catheter, and delivery apparatuses including the catheter devices coupled to endoscopes such as bronchoscopes. Methods of use of the catheter devices and delivery apparatuses are also described.

An embodiment of a system for treating sleep apnea includes a collar, pump, motor, sensor, memory, and controller, which is configured to store, in the memory, information related to sleep-apnea events or sleep-apnea treatment, experienced by the subject. For example, the controller can obtain, and store in the memory, information related to sleep-apnea events, and the controller, or another computing system, can correlate this information with the subject's lifestyle choices, and can recommend lifestyle changes to improve the subject's sleep apnea. Furthermore, the controller can obtain and store, in the memory, information related to usage and settings of the sleep-apnea system, and the controller, or another computing system, can correlate this information with the subject's wellbeing, and can recommend changes in the usage or the settings of the sleep-apnea system that can improve the subject's wellbeing.

The invention relates to a positioning sputum suction laryngeal mask. The positioning sputum suction laryngeal mask comprises a mask body and a mask body tube, wherein the mask body comprises a mask body bottom plate and a mask main body arranged on the mask body bottom plate, a central region in the mask main body is provided with a mask body cavity communicated with the mask body tube, a stomach decompression tube corresponding to the stomach mouth is arranged on the back side of the mask body bottom plate, and the stomach decompression tube is isolated from the mask body cavity through the mask body bottom plate. The positioning sputum suction laryngeal mask also comprises a connection suction mechanism capable of realizing negative pressure suction in a gas supply process. The connection suction mechanism comprises a suction connecting tube which is arranged in the mask body bottom plate, and the end, located in the mask body bottom plate, of the suction connecting tube is communicated with the stomach decompression tube. The positioning sputum suction laryngeal mask can be effectively positioned, has lower complexity and usage costs, can ensure the ventilation and sealing effect without air inflation in use, can realize suction of secretions in a ventilation process, can avoid airway blockage caused by epiglottis, and can improve the stability and reliability in use.
