Convergence in Health Care Technology: Devices, Biologics, Pharma, IT, Communications and Imaging  
Stephen N. Oesterle, MD, Senior Vice President, Medicine & Technology, Medtronic, Inc., stephen.n.oesterle@medtronic.com

Medtronic is one of the world’s largest producers of biomedical devices, employing 40,000 people worldwide and annually generating around $13 billion in revenue.  The company offers products to treat a broad range of chronic degenerative diseases; and every year, the company spends about $1.5 billion on research and development.  To continue its success, the company recognizes that it must adapt with the changing face of modern medicine.  Medtronic is thinking about several medical trends that will most likely occur over the next decades.  As the U.S. population ages, for example, chronic degenerative diseases will almost certainly become more common.  As diagnostic and therapeutic techniques improve, personalized medicine will replace “population” medicine, and restorative therapies will replace the palliative therapies that Medtronic focuses on now.  Medical devices will gradually become integrated with information technology, and the role of materials science in healthcare will expand.

 

The medical industry seems to be entering a new era.  In the first half of the twentieth century, medical therapies were often based on the extirpation of diseased tissue or organs.  More recently, therapies have depended upon the implantation of tissue, mechanical devices, or even organs.  With the medical community’s growing understanding of the human genome, these palliative techniques may soon be obsolete.  It appears to be a “central dogma of biotechnology” that all diseases can be reduced to protein imbalances, and many different therapies, from mRNA suppression to gene therapy, are being developed to treat these protein imbalances.  Medical devices will play a major role in this new medical age because molecular therapies will be most effective only if they are combined with site-specific delivery platforms.  Implantable physiologic sensors are also poised to become valuable medical tools, and in the not-so-distant future, small implanted devices may allow physicians to monitor a patient’s condition remotely via information transmitted over existing communications networks.  In this new age, medicine will increasingly involve the integration of the physical, life, and information sciences.

Challenges in Cardiac Device Development 
Donald S. Baim, MD, Executive Vice President, Chief Medical and Scientific Officer, Boston Scientific, donald.baim@bsci.com

 

The history of cardiac devices is one of iterative improvement.  When Gruentzig performed the first balloon angioplasty, the procedure was crude and did not have a great success rate; but over time, serial improvements made it into a widely used method of coronary revascularization.  Over the last two decades, stents have emerged as another means of treating stenotic arteries.  While stents have improved patient outcomes, they have also led to new complications, such as restenosis and stent thrombosis.  Drug-eluting stents were developed to prevent restenosis, but in 2006, a few studies were published suggesting that drug-eluting stents led to higher risks of death than bare-metal stents.  The use of drug-eluting stents decreased.  Further investigation and data analysis, however, revealed that the results of the original studies were skewed by confounding factors such as the fact that drug-eluting stents were disproportionately used in patients with diabetes and other background risks.  Second- and third-generation drug-eluting stents are being developed, and these stents seem to pose the same mortality risks as bare-metal stents. 

      

There are many financial advantages and disadvantages to manufacturing cardiac devices.  The advantages include the fact that heart disease is the leading cause of death in the U.S. and the fact that the problem is well suited to mechanical intervention.  Disadvantages include the fact that it takes a lot of time for a new device to be approved for use in people and the fact that the industry is becoming increasingly competitive.  View this video
