Software developed by Medtronic (Minneapolis) will give the company greater insight into performance issues on defibrillator leads from competing firms when attached to one of the med-tech giant's devices. The company said that it received FDA approval of the Lead Integrity Alert (LIA) software to report performance issues on St. Jude's (St. Paul, Minnesota) Durata and Boston Scientific's (Natick, Massachusetts) Endotak defibrillator leads when connected to a Medtronic device.
