Meridian
Iontophoretic Drug Delivery Electrode

Electrode showing fill tubes connected

Electrode and hold-down bracket

Assembled electrode and hold-down bracket

The new Meridian drug delivery electrode is designed for convenient iontophoresing of ionic compounds that are labeled for iontophoretic delivery as an alternative to hypodermic injection. This electrode is designed to be used with any FDA-market cleared iontophoretic stimulator, such as the Life-Tech Microphor Model 6111PM/DX (for more information, please see the Life-Tech physical medicine web site).

Features:

• A see-through plastic chamber: Allows a clear view for easy inspection of the contents.
• A unique circular shape: Leaves the area inside the circle untouched by the ionic solution.
• Constructed from a rigid plastic, three-sided chamber: The chamber becomes closed when attached to the patient’s skin.
• Easy to fill: Two tubes attached to ports on the chamber, one for filling and the other for overflow, minimize air bubbles as the soluble salt or drug solution of interest is introduced using a syringe.

Detailed Description:

A hold-down bracket with a Velcro strap can be used to keep the electrode in place. After the electrode is placed open-side down on the patient’s skin, a syringe filled with a soluble salt or drug solution of interest is inserted into a fill tube that leads to a port on the circular chamber. The solution is then introduced into the chamber via the fill tube. An overflow tube, affixed to the other port, allows the excess liquid to fill the chamber, minimizing air bubbles. Lastly, the technician closes the fill tubes. In this way, the soluble salt or drug solution comes in direct contact with both the patient’s skin and the stainless steel contact, which is attached to a standard lead connector for use with any one of a number of FDA-approved iontophoretic current generators.
      When the current is turned on according to the instructions provided by the maker of the iontophoretic stimulator and according to the maker of the drug, the drug ions are transferred into the skin according to conventional iontophoretic theory.
      It should be noted that the physician is responsible for determining which drugs to iontophorese and for ensuring that the drug is used according to its labeling. The physician is also responsible for determining that the drug is suitable for iontophoresis with the iontophoretic drug delivery electrode. This device acts simply as an active iontophoretic reservoir.
      When iontophoresis is finished, the skin capsule is removed and the excess liquid material on the skin is wiped away with a paper towel.

Specifications:

• Capacity: 1.14 cc
• Delivery surface area: 2.25 sq. cm.
• Made from biocompatible PETG material

Indications for Use:

This device is intended to use a direct current to introduce ions of soluble salts or other drugs into the body for medical purposes. (CFR 890.5525b / Class III)

Contraindications:

Iontophoresis is contraindicated for patients with known adverse reactions to the application of electrical current; cardiac pacemakers or other electrically sensitive implant devices; and known sensitivity to the drugs being administered.
