Try the Therapy First

Like test driving a car, the screening trial allows you to “test drive” targeted drug delivery before committing to long-term therapy.

  • Assess if targeted drug delivery may relieve your pain during daily activities.
  • Experience how it feels to receive pain medication targeted to the fluid surrounding the spinal cord, in an area called the intrathecal space.
  • Decide if you want to go ahead with an implant.

A system for pain relief

Discover how targeted drug delivery pump and personal therapy manager deliver pain relief.


Targeted drug delivery doesn’t cure the underlying disease, but it may help you better manage your chronic pain.

Before the trial:

  • You may have a psychological evaluation to help determine if you are a candidate.
  • Your physician may ask you to reduce or stop taking oral pain medications before the trial.
  • Your physician will recommend the trial method that makes the most sense for your situation and discuss the risks of the procedure with you.

The procedure usually takes place in a hospital or surgery center.


The general steps of each trial method may vary depending upon your physician.


This method uses a special needle filled with pain medication. A single dose or multiple doses of a small amount of medication is injected into the intrathecal space.


This method takes place over a few days using a temporary system that closely resembles the therapy delivered by the implanted drug pump.

After the trial

After the trial, you and your physician will discuss your experience and decide if an implantable targeted drug delivery system is right for you.


Complications can occur with the trial, including bleeding, infection, spinal headaches, damage to the spinal cord, and drug side effects.
