Medtronic SynchroMed II implantable infusion pump
Hazard alert – risk of sudden loss of therapy due to reduced battery performance
Consumers and health professionals are advised that Medtronic Australasia, in consultation with the TGA, has issued a new hazard alert for model 8637 SynchroMed II implantable infusion pumps manufactured before the end of June 2011. The new hazard alert reinforces previously communicated patient management recommendation regarding the potential for sudden loss of therapy due to reduced battery performance, for which Medtronic Australasia had originally written to health professionals about in July 2011.
Medtronic SynchroMed II implantable infusion pumps are programmable medical devices that deliver small amounts of medicine directly into the spinal fluid for the treatment of chronic pain or muscle spasticity.
Please note, this hazard alert does not affect Medtronic SynchroMed II implantable infusion pumps currently being marketed or implanted, or to any previously implanted devices manufactured after June 2011. In June 2011, Medtronic Australasia began distributing infusion pumps with a new battery design that resolved this issue.
