A nonreciprocal circuit device has a structure that allows a direct current magnetic field having an even density to be applied to a necessary portion of a ferrite without impairing a reduction in profile so as to improve insertion loss. The bulking agents can be used to treat such conditions as urinary and fecal incontinence, gastro-esophageal reflux, aneurismal blockages, and cosmetic deformities. Upon the application of sufficient heat to the connector, the connector shrinks around and onto the sleeve cuff and plug portion to form a relatively thin, smooth, mechanical attachment between the sleeve cuff and plug portion. A pressure-sensitive adhesive is used to re-adhere the marginal region to an underlying surface of the inner structure adjacent the opening through the laminate.
