is recalling one of its products, the medical device maker reported on Wednesday.
The company is voluntarily recalling some of its 3.0 millimeter Multi-Link Vision coronary stents due to manufacturing problems. The recall affects only certain lots of the cobalt chromium stents, which are used to keep open heart arteries following a procedure to unclog blood vessels. Trading in Guidant shares was halted before the announcement.
Guidant did not say how many stents it is recalling, but did say that patients who had already received the Vision stents were not affected by the recall. The company said it has already notified physicians and various regulatory bodies about the recall.
The recall targets stents shipped to Europe and Australia, as well as the United States.
Guidant representatives did not immediately return calls seeking comment about the recall.
After being the market leader last year, Guidant has been
losing ground in the stents market this year. The company is running behind the competition in developing a drug-coated stent. Such devices, which have proved better at preventing arteries from becoming clogged again, are expected to replace the current generation of bare-metal devices.
