Advances in Medical Device Technology for Cardiovascular Applications (Technical Insights)
Frost & Sullivan, March 2005
Higher Incidence of Cardiovascular Diseases Sees Advances in Medical Devices for Cardiovascular Applications
The growing use of tobacco combined with poor nutritional habits and unhealthy lifestyles are contributing to an increase in incidence of cardiovascular diseases in the developed world. Remedies for conditions such as congestive heart failure (CHF) and atrial fibrillation (AF) are currently very limited and there is greater emphasis on finding treatments that are more successful. While significant advancements are being observed in the fields of interventional cardiology and minimally invasive surgery, pacemakers, coronary stents, implantable cardiac defibrillators, and angioplasty products are dominating the world market for cardiovascular products. Of these, the United States market is seeing the most notable innovations and developments.
This Technical Insights research service studies advances in cardiovascular medical device technologies. It provides information on organizations, companies, universities, research institutions, and government labs involved in R&D, along with their contact details. A summary of key patents is likely to give an insight into notable activities, technology trends, and major participants involved in the development and application of these technologies.
Development of Stent Technology Draws Greater Focu
Currently, some predominant technological advancements are focused on the development of stent technology. Drug-eluting stents have been highly successful and have prevented complications such as restenosis and thrombus - conditions that are associated with the use of bare metal stents. With the assurance of extremely low restenosis rates, many physicians estimate that up to one-third of surgical interventions (coronary artery bypass grafting procedures) can be avoided with the use of drug eluting stents. Also, as technology improves, physicians can better treat patients who are deemed unfit for surgery or angioplasty. Bio-absorbable stents, along with stents coated with bioengineered surfaces are, are expected to dominate the market for interventional cardiology. The opportunity to treat vulnerable plaque could add further expand the coronary stent market.
Cardiac rhythm management is a high-technology application, and advancements in this field are related to the development of easily implantable devices, that have greater longevity and better diagnostic and therapeutic capabilities. These devices are being modified to treat various comorbid conditions such as atrial fibrillation associated with heart failure. The current focus of development is on reaching lower defibrillation thresholds, which is likely to lead to conservation of energy and subsequently, enhance generator life, says the analyst of this research service. Miniaturization is also being pursued actively, with efforts aimed at reducing the generator size and volume.
Increase In Elderly Population Stimulating Demand for Cardiovascular Medical device
The majority of implants in the recent past have been developed for patients who are more than 50 years old. Globally, an aging population and their increasing need for healthcare services have created a huge demand for products that treat cardiovascular illnesses. Consequently, this stimulates the demand for cardiovascular medical devices and this growing population is expected to be a powerful driver for the advancement of medical devices for cardiovascular applications.
The highly competitive nature of the cardiac devices market has forced manufacturers to consolidate their resources through mergers and alliances. This has increased the dominance of larger companies and made it more difficult for the smaller participants to compete, says the analyst. There may be further consolidation in the future and the bigger companies with wider product mixes and more polished distribution channels are likely to enjoy better equity with the medical fraternity.
