Abstract
An insertion set for insertion into a skin of a user. The insertion set includes an insertable substantially insoluble flexible portion and a soluble material. The insertable substantially insoluble flexible portion is capable of remaining in the skin after insertion. The soluble material is coupled to the insertable insoluble flexible portion and facilitates piercing the skin, and the soluble material dissolves in the skin of the user. Also, the soluble material holds the substantially insoluble flexible portion in a rigid state. Preferably, the insertion set is an infusion set or a sensor set. The sets may include a cannula as part of the insertable substantially insoluble portion. The cannula may be formed from a flexible material or a flexible metal tube. Preferably, the soluble material is formed from a at least one saccharide, such as a monosaccharide or a polysaccharide, a protein, a starch, other biocompatible materials, or the like.
