Abstract
A medical device includes a radially expandable and contractible tubular element, having proximal and distal ends, sized to pass through the nostril and into the user's upper airway when in the radially contracted condition. The support element may create an air passageway therethrough when in a radially expanded condition. The tubular element may comprise a porous filter section for filtering air passing through the air passageway. The tubular element may comprise a body material and an agent releasable from the body material for delivery to tissue of the user when the tubular element is radially expanded.
Claims34
A device for delivering an agent to tissue of a user comprising:
- a radially expandable tubular element having proximal and distal ends;
- the tubular element sized to pass through a nostril and into the user's upper airway to be positioned at a desired location within the user's upper airway so that when the tubular element is radially expanded, an air passageway is created within the support element between the proximal and distal ends;
- and
- the tubular element comprising a body material and an agent releasable from the body material when the tubular element is radially expanded.
A method for delivering an agent to tissue of a user comprising:
- selecting a radially expandable tubular element having proximal and distal ends;
- placing the tubular element through a nostril and into the user's upper airway;
- positioning the tubular element at a desired location within the user's upper airway;
- radially expanding the tubular element thereby creating an air passageway within the tubular element between the proximal and distal ends;
- the selecting step further comprising choosing a tubular element comprising a body material and an agent releasable from the body material;
- and
- releasing the agent for delivery to tissue of the user.
