As
the global trend towards rising health concerns takes pace and increasing adult
diseases coupled with environment pollution, a strong emphasis is placed on the
importance of treatment and prevention via diagnosis. Due to this shift to
rising research coupled with wellness, the demand for advanced medical devices
is expected to increase at a fast pace. As the global population ages,
identification and treatment of heart diseases has gained paramount importance.
Various reports conducted by scientists reveal that major cause for natural
deaths in human beings is related to heart one way or the other which
translates into greater demand for heart treatment devices especially stents.
According
to the study, ‘Coronary
- Medical Devices Pipeline Assessment, 2018’, some major institutions
and organizations developing this technology are Abbott Vascular Inc.,
AlviMedica Medical Technologies Inc., Amaranth Medical Inc, Boston Scientific
Corp, Cardionovum GmbH, Cardiorev Pte Ltd, Medinol Ltd, Medlogics Device Corp,
Medtronic plc, S3V Vascular, Technologies Vornia Biomaterials Ltd and
Xenogenics Corporation. The top 3 companies that are Abbott, Boston Scientific,
and Medtronic enjoy a huge share in the market place and thus make the entry of
new players significantly difficult.
Stents
are basically of two categories, vascular and non vascular stents. Vascular
stens are further sub divided into coronary, peripheral, and neurovascular
stents. A coronary stent is a device
which is tube shaped which is used to keep the arteries open for the treatment
of coronary heart diseases. Peripheral arteries are balloon shaped device used
to treat stenotic lesions in different arteries. These stents are not used to
treat coronary, cervical or cerebral vessel. Neurovascular stents are used for
treating severe carotid artery stenosis. These stents are particularly used for
high surgical risk patients.
Many
innovations have taken place in order to improve the efficiency of a particular
stent. For instance latest requirement was to make stents more flexible and
therefore they are covered with CoCr allow to improve their elasticity. Many
stents suffered from stent restenosis. In order to prevent this condition,
stents are being covered with an immunosuppressive agent; these stents have gained
widespread popularity in Korea. The current technology being worked upon is
stents that are dissolved in the heart after their application is completed.
Although many stent manufacturers are developing this technology, the rate of
acceptance and adoption in clinical trials is low. However, once this
technology is developed it shall bring a paradigm shift in the global stent
market. Due to various anti-proliferative drugs and the polymer coating of the
drug, the options available with patients have expanded. Scientists have
recently conducted clinical trials for biocompatible scaffolds. The current
trends in advances in the stent technology are mainly driven by rising DES that
are drug eluting stents.
There
can be variations in the results of global stent market 5 years down the line,
however many predict this industry is expected to grow at a rapid rate and an
increased growth rate in the biodegradable stent market due the benefits of
application it posses. Social cost associated with manufacturing this device
can also rise in the future thus making it absolutely necessary to make these
devices patient friendly especially for old age population.
