Dr. Alimorad Farschcian said Jackson told him that he wanted to stop taking Demerol for the sake of his children. The Miami-based physician became close to the entertainer after treating him for a sprained ankle, spending time at Neverland Ranch and meeting Jackson's mother on Christmas Day in 2002.
Farschcian said the implant kept the singer off of Demerol for at least nine months and Jackson's mother Katherine seemed pleased when he described it to her and her son showed her the device.
Katherine Jackson testified on Monday that she never saw the device and could never prove her son abused prescription medications.
The Jackson family matriarch is suing AEG Live, claiming it negligently hired another doctor, Conrad Murray, who was convicted of administering Jackson a fatal dose of anesthetic in 2009. No trace of Demerol was found in Jackson's system when he died.
AEG Live denies it hired Murray, and its attorneys have said Jackson hid his addiction struggles, and the company bears no responsibility for his death.
Superior Court Judge Yvette Palazuelos said she would consult with another judge about how to handle Wagener and the photo of jurors.
