Abstract
Disclosed are medical articles and processes for forming the medical articles. The medical articles may take the form of a sponge having a three-dimensional shape comprising a reservoir. In an embodiment, the sponge is formed by placing a collagen slurry, optionally further comprising a mineral, in a mold and lyophilizing the slurry. In an embodiment, an improved molding process for such medical articles comprises forcing a slurry through a mold comprising the shape of a tube having an obstruction connected to the sidewall of the tube via an arm extending from the sidewall to the obstruction.
