The catheter assembly comprises a generally oblong inflatable catheter defining at least one catheter volume and the catheter is configured to assume a shape suitable for insertion into a nasal cavity and to assume a shape suitable for stimulating a nasal tissue. The catheter assembly also comprises a tube part comprising at least one lumen configured to establish fluid flow connection between said fluid flow generator and catheter. Preferably, the catheter assembly comprises at least one vent for releasing fluid or permitting fluid to escape from the generated fluid flow. The fluid flow generator of previous aspects of the invention is configured to generate at least one of a smooth continuous flow, an oscillating flow and a pulsating flow.

Embodiments may include systems and methods for treating an occluded area in a body, accessing cavities or passages of the body, or reducing pathologic material in the body. Embodiments may be configured to apply vibratory energy to pathologic material in a treatment area of a body. A handle connected to an energy source may be configured to provide an energy signal. A transducer may be configured to receive the energy signal. An effector may be operatively coupled to the transducer. The effector may have a proximal end connected to the handle and a distal portion configured to apply vibratory energy to pathologic material. A cannula may have a longitudinal passage to receive at least a portion of the effector and/or be configured to expose at least the distal portion of the effector to the pathologic material or the treatment area.

A cold plasma system and method for treating a region of a biological surface is presented. In one embodiment, the system includes: a housing; an air conduit within the housing; a first electrode configured proximately along the air conduit; a second electrode configured proximately along the air conduit and opposite from the first electrode; and a source of alternating current (AC) electrically connected with the first electrode. The source of alternating current is configured to generate cold plasma in the air conduit.

A device, a system and a method are provided to accurately apply a medically beneficial substance directly to a laterally or superiorly located paranasal sinus cavity. When the device is assembled with a solution in a reservoir, and inverted such that the reservoir is above an input apparatus and a housing, weight of the solution pushes down on a diaphragm creating a negative pressure on the diaphragm, which prevents air from entering the reservoir and prevents a liquid from flowing out of the reservoir. Applying a positive pressure to a bottom of the diaphragm causes the diaphragm to open and allows air to flow into the reservoir. When a user creates the positive pressure by exhaling air into the device the act of exhaling causes the user's choana to close. Thereby any solution introduced into the user's sino-nasal cavity will remain contained within the user's sino-nasal cavity increasing effectiveness of treatment and decreasing user discomfort including gagging, choking, and inner ear disturbance. When the positive pressure on the bottom of the diaphragm is removed, the flow of the liquid from the reservoir stops.

A multifunctional portable tool is provided, which includes a housing; a motor received in the housing and having a first output end; a pump head movably received in the housing and having a driven shaft that is connectable with the first output end; and a first reset mechanism disposed between the motor and the pump head. The multifunctional portable tool has a first working state in which the driven shaft of the pump head is connected with the first output end of the motor so that the pump head and the motor together function as a pump, and a second working state in which the pump head is driven by the first reset mechanism to move away from the motor until the driven shaft of the pump head is disconnected with the first output end of the motor.

A nasal irrigation device communicates an irrigant to a device user and comprises a mechanics module and a reservoir assembly wherein a source of saline comprising a cartridge is disposed within the mechanics module adjacent a lid assembly for piercing the cartridge upon closing of a lid for releasing the cartridge contents into the reservoir assembly. A faux collapsible cartridge for testing operability of a nasal irrigation device comprises a housing including a shaft, a spring biased rod extending from the housing shaft, and a flange depending from a housing wall whereby the rod and flange are disposed to actuate a trigger assembly of the nasal irrigation device.

The present invention discloses a positive-pressure double-nozzle nasal cavity cleaner featuring double pressure protection, and relates to the technical field of health care. The nasal cavity cleaner consists of a nose washing end, an upper shell, a core module, a control module, a lower shell, a liquid reservoir and a waste reservoir, wherein the nose washing end is rotatably connected to a top portion of the upper shell, and the nose washing end consists of a silicone washing nozzle, a silicone backflow nozzle and a rotary connecting base. The nasal cavity cleaner uses positive pressure and automatic pressure relief structures to obtain safe and constant air pressure, and then presses normal saline into the nasal cavity to clean the nasal cavity, so that pressure in the nasal cavity is small and stable during cleaning, which prevents damage to the nasal cavity and ear canal, thus being safer to use. Besides, deeper areas can be washed, nasal scabs in the nasal cavity can be moistened and removed, harmful substances such as dust in the nasal cavity can be removed, the nasal cavity can be moistened, and normal swing of nasal cilia can be recovered, which are helpful in treating rhinitis and preventing the onset of allergic rhinitis.

An assembly for nasal irrigation for the handheld irrigation of a user's nasal cavity comprising a housing with a refill chamber containing irrigating fluid, an applicator, an actuator for forcing irrigating fluid from the refill chamber through the applicator into the user's nasal cavity during operation, and a solution port for refilling the refill chamber. Some embodiments of the present invention may further comprise a system for nasal irrigation that includes the assembly for nasal irrigation or handheld irrigator, as well as a solution assembly structured for dispensing irrigating fluid to the handheld irrigator, a docking station for removably housing the handheld irrigator, a solution assembly and a refill control, including a check valve.

Described here are devices, systems, and methods for treating one or more conditions (such as dry eye) or improving ocular health by providing stimulation to nasal or sinus tissue. Generally, the devices may be handheld or implantable. In some variations, the handheld devices may have a stimulator body and a stimulator probe having one or more nasal insertion prongs. When the devices and systems are used to treat dry eye, nasal or sinus tissue may be stimulated to increase tear production, reduce the symptoms of dry eye, and/or improve ocular surface health.
