St Jude shares slump with more problematic cardiac leads
This article was originally published in Clinica
St Jude Medical's shares suffered a slump yesterday after it announced it would stop selling its QuickSite and QuickFlex left ventricular leads, after finding cases of externalised conductors. The problem occurs when the insulation around the leads has worn down to the point where the electrical conductors are exposed. The leads are used with St Jude's cardiac resynchonisation therapy (CRT) implanted devices, which are implanted in patients with heart failure.
