New Trial Will Test Efficacy of Spinal Cord Stimulation in Treating Heart Failure

July 29th, 2010 Smit Shah Cardiology

Medtronic announced today the start of its Defeat-HF study, in which the company will attempt to treat heart failure through the use of spinal cord stimulation (SCS). Trial subjects will be implanted with Medtronic’s PrimeADVANCED neurostimulation device, which is currently being used for pain management. The treatment’s efficacy will be evaluated based on heart size, muscle wall thickness, fatigue, shortness of breath, and quality of life improvements.
An explanation from Medtronic’s press release:

Heart failure stimulates the sympathetic nervous system further progressing the disease. The Defeat-HF study will evaluate whether SCS can restore the natural balance between the sympathetic and parasympathetic nervous systems to improve blood flow, reduce inflammation and restore the heart’s dimensions and function. The study will be conducted under an Investigational Device Exemption (IDE) in the United States.
The prospective, randomized, feasibility trial is expected to enroll NYHA Class III systolic heart failure patients at up to 15 centers worldwide. All patients are implanted with a Medtronic PrimeADVANCED™ neurostimulator and followed for 12 months. In this trial, the device delivers stimulation for 12 hours a day.

By attending this seminar, you will discover:

How to overcome one of the biggest obstacles device manufacturers face
How the FDA expects you to develop and implement proper handling of complaints reportable or non-reportable, product complaint handling and documentation
How and when to file Medical Device Reports (MDR), effective and appropriate communication with the appropriate regulatory agencies in the event of a recall.
How to conduct a correction and removal actions to avoid a recall crisis, including required recordkeeping, expectation from FDA and other regulatory agencies in the event of a recall and key factors in implementing and maintaining compliance with the regulations and real life experiences of FDA.

**New course materials have been added, updated content will include:

Creating Standard Operating Systems (SOPs) for Post-Market Quality Systems and
What to expect from the changes in ORA with Inspection Structure Realignment

This Seminar will have you stop spinning your wheels with nonessential activities, and leave you with a comprehensive learning package that only Rita Hoffman, a former FDA CDRH Recall Branch Chief with experience across the device, drug and veterinary industries can provide.

Spend one and a half days in an interactive course led by Ms. Rita Hoffman, Former FDA CDRH Recall Branch Chief with over 36 years with FDA and leading Industry Expert, who will provide the participants with tools to minimize risk of regulatory enforcement actions.
