Allergan Inc. said in a statement that it has "made the decision to presently discontinue the sale of the Lap-Band … to all entities affiliated with 1-800-GET-THIN."
A representative for the surgery centers issued a statement saying the clinics were disappointed with Allergan's decision but would continue working with patients who want to lose weight.
"Our surgery centers are staffed with experienced bariatric surgeons, trained by Allergan on the proper procedures for implanting the Lap-Band," the statement said. "Patients interested in weight loss solutions have a range of options, of which the Lap-Band is only one. We will continue to work with our patients to find the best healthcare options for their medical needs."
Five Southern California patients have died since 2009 after undergoing Lap-Band surgeries at clinics affiliated with 1-800-GET-THIN, according to lawsuits, autopsy reports and other public records. Each of the patients had been treated at surgery centers in Beverly Hills and West Hills tied to the ad campaign, according to the records.
Allergan is the world's top manufacturer of surgically implanted bands that constrict the stomach to limit food intake. It controls more than 80% of the market, according to the company.
1-800-GET-THIN has featured the Lap-Band prominently in its advertising.
Allergan spokeswoman Caroline Van Hove declined to elaborate on the device maker's decision to cut off a major group of customers. "We do not discuss our customer relationships with third parties," she said.
Allergan has said in previous comments to The Times that it was legally prohibited from banning sales to the surgery centers tied to 1-800-GET-THIN. It did not explain why it was able to take that step now.
In recent months, local, state and federal regulatory agencies have been examining the 1-800-GET-THIN affiliates amid questions about the advertising, surgery-related deaths and accusations of insurance fraud.
The California Department of Insurance is investigating the surgery centers for alleged insurance fraud, said David Althausen, a spokesman for the state agency.
In December, the Food and Drug Administration warned 1-800-GET-THIN and the surgery centers that the ads were misleading because they failed to adequately disclose risks of the surgery.
Allergan's decision could prove challenging to 1-800-GET-THIN because its marketing campaign is so closely tied to the Lap-Band brand, said Lars Perner, assistant professor of clinical marketing at the USC Marshall School of Business.
Lap-Band procedures typically cost between $12,000 and $20,000, according to Allergan.
Publicity about the Southern California deaths and investigations of 1-800-GET-THIN have hurt at least one surgeon who performs Lap-Band surgeries but who is not connected to the marketing company.
"Our Lap-Band business has come to a screeching halt," said Dr. Carson Liu, a Santa Monica bariatric surgeon who praised Allergan's decision. "I've been trying to get the word out that there's a difference between the Lap-Band and 1-800-GET-THIN."
Alexander Robertson, a Westlake Village attorney who has filed several lawsuits against 1-800-GET-THIN and its affiliated surgery centers, applauded Allergan's decision.
His clients include relatives of patients who died after Lap-Band surgeries and former employees who accused the surgery centers of performing unnecessary surgeries and of billing insurers for procedures that were not performed.
