The ON-Q® Post-Operative Pain Relief System from I-Flow Corp. is a balloon-like pump that provides targeted pain relief after surgery by automatically delivering a non-narcotic local anesthetic near the surgical site area. The system works like this:

• The pump is attached to a catheter that the surgeon places near the incision site.
• Medicine is automatically delivered via the pump at a slow flow rate.
• The pump may last 2 to 5 days. 
• The pump is completely portable, lightweight and can be attached to a gown or clothing or placed in a carrying pouch.
• When the infusion is complete, the catheter is removed and the pump is thrown away.
• Depending on the surgery, the patient may go home with one of these pain relief systems.
• The system can be used in orthopedics, CV/CT, bariatrics, general, plastic, OB/GYN, urological, colorectal and trauma.
