Abstract: A device for delivery of medicaments to epidermal and mucosal surfaces, comprising a microporous outer portion made from polymeric foam, and a macroporous inner portion made from polymeric foam disposed within the outer portion and in substantial communication with the outer portion which is adapted for incorporating a medicament therein, wherein the macroporous inner portion has at least one free surface not in communication with the microporous outer portion, and the pore size ratio of the macroporous inner portion to the microporous outer portion is between about 2 to 1 and 1.67 to 1.

Abstract: A microscope inspection slide including at least one examination chamber formed by bonding together a base plate and a cover plate. The base plate having a chamber floor surface raised above a deck surface on the base plate, and the cover plate having a roof surface with a depth control ridge positioned about a portion of the edge of the chamber roof surface. Bonding the cover plate to the base plate forms an examination chamber with the distance between the roof surface and floor surface maintained constant, and entrapped gases and excess fluid allowed to drain from the examination chamber through notches in the depth control ridge.
