Until a few years ago, “drug delivery” simply meant swallowing a pill. Today, this is a huge field of research that will allow clinicians to bypass the body’s defenses to treat previously untreatable conditions and to even automate treatments by medicating patients whenever certain measured parameters are met.

Here are a few devices that are said to revamp the conventional methods of drug delivery systems:

- A smart Bluetooth-powered electronic pill developed at MIT can reside in the stomach for over a month while releasing drugs whenever needed. It eventually breaks up into pieces and exits the body without leaving anything behind. Read more about this device here:

- A heart that survives a cardiac infarct can benefit from a number of medical compounds, but those are normally delivered by injection and therefore influence the entire body. A team of researchers from the U.S. and Ireland have developed a device that can be used to deliver drugs directly to a damaged region of a heart. One end of the device is stuck to the heart, while the other end is an injection port that protrudes through the skin. A syringe can be used to push drugs through the port and into the damaged area of the heart. Read more about the device here:

- Like the heart, the eyes are also difficult in terms of drug delivery. The eyes wash away anything that lands on them and have a number of defenses to prevent things from penetrating into the interior of the eye. EyeGate II iontophoresis drug delivery system uses electric current to gently push ionized drug molecules through the eye. An electrode is placed on the patient’s forehead, while the opposite electrode is within a special applicator. The applicator ionizes the drug, while an electric current running between the electrode pulls the ionized particles along with it. Read more about this drug delivery system here:
