Abstracts

The United States Implantable Neurostimulators Industry Report 2016 is a professional and in-depth study on the current state of the Implantable Neurostimulators industry.

Driven by technology advancements, rising consumer awareness, and development of sophisticated implantable neurostimulation devices, USA market for neurostimulation is projected to reach $2.3 billion by the year 2015 and ranks as the single largest market for neurostimulation worldwide. Conducive demographics like the aging world population offers ample opportunities for growth in the upcoming years. Emergence of new indications for the use of the neurostimulation therapy is expected to result in expanded market opportunities.

The world neurostimulation market stands enthused by the growing base of aging population, and the resultant rise in age-related diseases such as, Parkinson's, and Alzheimer's disease. Widespread prevalence of neurological disorders and conditions, and the associated costs to society in terms of declining productivity, and reduced quality of life, offer a business case for the neurostimulation treatment modality.

With public and private health insurance companies mulling reimbursements for neurostimulation procedures and devices, the market stands to gain attractively in the medium to long run.

Leading global and regional players operating in the industry include Boston Scientific Corp, St. Jude Medical Inc, Cyberonics Inc, Medtronic Inc, Cyberkinetics Neurotechnology Systems Inc, and Synapse Biomedical Inc, among others.

The report provides a comprehensive review of the market trends, drivers, issues, and challenges. The report provides unequivocal views on future potential while throwing light on the prevailing climate in key product markets. Product markets analyzed in the report include Spinal Cord Stimulators (SCS), Deep Brain Stimulators (DBS), Sacral Nerve Stimulators (SNS), Vagus Nerve Stimulators (VNS), and Gastric Electric Stimulators (GES), etc. Latent demand patterns in product markets are quantified mainly about the United States. Also provided in the report is an enumeration of recent mergers, acquisitions, and other strategic industry activities.
