Abstract
An shaped iontophoresis device is capable of permeating an active agent (e.g., a drug solution) into an oral cavity, a skin cancer, or the like by iontophoresis in a pinpoint manner. A catheter-type iontophoresis device includes a small working electrode assembly and a small non-working electrode assembly at the tip of a holding portion. A first ion exchange membrane and a fourth ion exchange membrane at the tips of the assemblies are brought into close contact with a target area so that a drug solution is permeated by iontophoresis in a pinpoint manner. The working electrode assembly and the non-working electrode assembly are attached to the tip of a rod-shaped member. The rod-shaped member is detachable from the tip of the holding portion, and is exchangeable integrally with the portion. The iontophoresis device may advantageously take the form of a rod or catheter.
