    摘要： Described herein are passive nasal device having a resistance to exhalation that is greater than the resistance to inhalation. Also described are devices, methods and systems for sensing and measuring intranasal pressure when a subject is wearing a passive nasal respiratory device that is configured to inhibit exhalation more than inhalation. Also described are adapters for nasal devices and methods of using a nasal device adapter. Adapters may be used so that a passive nasal device may be applied indirectly in communication with a subject's nose; in some variations this may allow the passive nasal device to be re-used. Also described herein are nasal devices having a billowing airflow resistor that is configured to have a greater resistance to exhalation than to inhalation. The billowing airflow resistor typically includes a first layer that is adjacent to a second layer; the first layer is flexible and billows opens during inhalation so that the first layer remains separated from the second layer, but remains substantially parallel to the second layer. During exhalation, the first layer collapses back down against the second layer. Additional passive nasal devices, systems and methods of using them are also described.

    摘要： This is directed to containers and methods for holding and delivering vaso-occluding materials such as hydrogel particles and filaments. The vaso-occlusive materials may be held in the container in a hydrated or unhydrated state. The container includes a fluid ingress port and a fluid egress port that are respectively fluidly connectable with a fluid source and a delivery catheter. The container further includes at least one chamber or passageway extending therebetween. The passageway may be straight, curved, spiral, helical, narrow or otherwise shaped. The chamber may also have sections of varying cross section such as a ramped section. The shapes of the passageways of the container help organize ejection of the vaso-occluding materials minimizing contamination and clumping. Methods for holding and introducing the materials are also provided.
