System and process for tobaccoless nicotine delivery

This application claims the benefit of U.S. Prov. Appl. No. 60/992,217, filed Dec. 4, 2007, the entire content of which is incorporated herein by reference.

1. Field

The present invention relates to a system and method for tobaccoless nicotine delivery.

2. Description of the Related Art

Current nicotine phase out systems utilize devices do not closely resemble the actual system and act of smoking. Completely eliminating the tactile and habitual sensations that are part of the cigarette experience may delay the adoption of the therapy by habitual smokers. For example, the nicotine patch completely removes the tactile sensation of the hand-to-mouth motion of smoking. Certain nicotine inhalation devices use a system that resembles a cigarette but are composed of materials that do not look or feel like cigarettes, such as plastic mouthpieces and metallic or plastic cartridges.

Thus, a need exists for a smoking cessation therapy comprising a nicotine replacement or phase out device that more closely resembles a cigarette and the experience of smoking a cigarette.

These and other systems, methods, objects, features, and advantages of the present invention will be apparent to those skilled in the art from the following detailed description of the preferred embodiment and the drawings.

A tobaccoless nicotine delivery device permits delivery of nicotine in a manner similar to a cigarette. The device may include an impermeable outer layer surrounding a micro-encapsulated nicotine layer that includes a measured amount of nicotine in a form that allows nicotine vapor to be released upon rupture of the micro-encapsulation. A permeable membrane may be disposed adjacent to the micro-encapsulated nicotine layer that allows pressure to be applied to the micro-encapsulated nicotine layer while permitting permeation of released nicotine into a central channel for inhalation by a user. A mouthpiece may be disposed at an open end of the central channel in order to provide air resistance to simulate the inhalation effect of a cigarette.

All documents mentioned herein are hereby incorporated in their entirety by reference. References to items in the singular should be understood to include items in the plural, and vice versa, unless explicitly stated otherwise or clear from the text. Grammatical conjunctions are intended to express any and all disjunctive and conjunctive combinations of conjoined clauses, sentences, words, and the like, unless otherwise stated or clear from the context.
