Infusion Set

Rigid soluble materials for use with needle-less infusion sets, sensor sets and injection devices and methods of making the same

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.

Transcutaneous inserter for low-profile infusion sets

A low-profile inserter for an angled infusion set comprises an inserter housing having a bottom wall, a retainer slidably connected to the inserter housing for movement between retracted and extended positions in a direction substantially parallel with the bottom wall, and a base member connected to the inserter housing. The retainer is adapted to releasably receive a cannula assembly, including a cannula connected to a cannula housing. The base member has a lower surface that is adapted to contact a skin outer surface. The lower surface and bottom wall together form an acute angle. With this arrangement, the cannula can be inserted subcutaneously at the acute angle with respect to the skin outer surface.
