Abstract
Single-chamber coatings are provided. The single-chamber coating includes a first medium, a second medium, and a ridge structure. The first medium covers at least a first portion of the second medium so as to form a chamber. At least one material property of the first medium is different than the second medium. The first medium forms a first wall of the chamber. The first wall is configured to apply a restorative force upon deformation of the chamber. The ridge structure is along a second wall of the chamber and is configured to direct the second medium substantially parallel to a ridge structure plane when the chamber is deformed. The chamber forms at least a portion of a coating. The coating is configured to be attached to an object that is configured to be inserted into an orifice.
