Abstract
A narrow-orifice foreign body extraction device configured as a unitary article comprises a volumetric enclosure bounded by a frustoconical cone, which has inner and outer surfaces and an intermediate section positioned between an apertured cap section and an apertured base section. The inner surface defines a boundary of an interior chamber of the volumetric enclosure, and the inner and outer surfaces define between them a cone wall. An adhesive material is secured to at least part of the inner or outer surfaces at the cap section and comprises an apertured portion and a tail portion. The apertured portion has one or more adhesive apertures and adhesive-covered opposing inner and outer side surfaces, and the tail portion has an adhesive-covered inner tail surface extending along and bonding to at least part of the outer surface at the cap section to secure the adhesive material to the cap section.
