pump at the Computer Security conference Black Hat Briefings, allowing an attacker to take control of the pump. Medtronic responded by assuring users of the full safety of its devices. In 2008, a team of computer security researchers was able to take remote control of a Medtronic cardiac implant. The team, using an unused implant in a lab, was able to control the electrical shocks delivered by the defibrillator component and even glean patient data from the device. In February 2020, Medtronic recalled around 322,000 MiniMed insulin pumps with faulty pump retainer rings, which had been correlated to death and around 2,000 injuries. Portable ventilators On 30 March 2020, Medtronic shared its portable ventilator design specifications during the outbreak of COVID-19 pandemic, in order to accelerate global ventilator production. Subsidiaries Vitatron Vitatron is a Netherlands-based European subsidiary of Medtronic. It is focused on development and manufacturing of cardiac pacing technology. Once an independently operating Dutch medical company, it was acquired by Medtronic in 1986. Vitatron pacemakers are interrogated and programmed by Medtronic Carelink Model 2090 Programmer for Medtronic and Vitatron Devices, using a separate interface. History of Vitatron 1956: Vitatron founded 1962: First Implantable pacemakers 1981: Microprocessor-driven, software-based pacemaker (DPG1) 1982: Rate Responsive pacemaker (TX1) 1984: Quintech DDD with automatic upper rate behavior ("mode switch") 1988: Daily Learn algorithm (Rhythmyx) 1997: First upgradeable pacemaker system with dedicated AF diagnostics, rate and rhythm control therapy. 2003: Vitatron goes digital: 1st Vitatron C-Series, the world's first fully digital pacemaker. 2004: 2nd Vitatron C-Series, digital, fast pacemaker. 2004: Vitatron T-Series: The full picture, digital pacemaker system. 2005: Vitatron C-Series, A3 models, a new top line range of digital pacemakers for bradycardic patients. Public-private engagement Activism Medtronic is a corporate partner of Human Rights Campaign, a large LGBT advocacy organization. Criticism Animal rights In 2005, 2008, and 2010 PETA threatened to submit a shareholder resolution to improve animal welfare standards in the company. In 2005, PETA attempted to stop five specific animal experiments that it deemed "crude and cruel". In 2008, PETA protested the outsourcing of animal testing to countries with lax animal welfare laws, such as China. In 2010, PETA attempted to stop Medtronic's reported use of live animals in testing and training. In response, Medtronic conducted a feasibility study that found that banning the use of live animals was impractical. As of 2015 Medtronic continued to use live animals for testing and
