    • The present invention encompasses a large variety of discrete structure all intended to be applied externally to a subject for the purpose of dilating, or lifting, tissue adjacent to nasal passageways of the subject, including the vestibule and/or the valve of the subject so as to decrease resistance to inhalation and exhalation of said subject during respiration. The tissue dilators of the present invention include those having at least one resilient member providing a first biasing force, or restoring force, so that when mechanically coupled to dilate adjacent tissue of a subject, the dilator constantly exerts a force developed to return the resilient member to an unbent state. In addition, a second biasing force may be applied to assist in producing a desired dilation of tissue of a subject that acts in concert with the first biasing force to impart an additional amount of force to dilate tissue of a subject.
    • 本发明包括各种各样的离散结构,所有这些离散结构都旨在从外部应用于受试者,目的是扩大或提升临近受试者的鼻腔通道的组织,包括受试者的前庭和/或瓣膜,例如 以减少在呼吸期间对所述受试者吸入和呼出的阻力。 本发明的组织扩张器包括具有提供第一偏置力或恢复力的至少一个弹性构件的组织扩张器,使得当机械地联接以扩张对象的相邻组织时,扩张器不断施加产生的力以使弹性构件返回 到一个不折不扣的状态。 另外,第二偏压力可以被施加以帮助产生与第一偏压力协同作用的对象的组织的期望扩张以赋予额外量的力以扩张对象的组织。
