Bottom Line: As an important branch, the medical device has achieved significant progress in the past decades.In the present study, we retrieve literatures about the medical device from the Web of Science™ (2004-2013), and acquire 26,793 related records, then analyze time range, region distribution, and main research directions of the literatures, and try to use keywords combined with mapping knowledge to explore the main trends of the medical device, and then aim to provide more information for medical device research.We provide a systematic approach for researchers to keep abreast of the development and state of the research of medical devices.

ABSTRACT
Biomedical engineering has been one of the hottest fields in biology and engineering. As an important branch, the medical device has achieved significant progress in the past decades. As a useful method in evaluative bibliometrics, mapping knowledge has been used to explore the trend of one field. In the present study, we retrieve literatures about the medical device from the Web of Science™ (2004-2013), and acquire 26,793 related records, then analyze time range, region distribution, and main research directions of the literatures, and try to use keywords combined with mapping knowledge to explore the main trends of the medical device, and then aim to provide more information for medical device research. Through the study, we discover: 1) the publications regarding medical devices show an upward trend over the past decade in general; 2) the percentage of publications in the USA (38.49%) is the highest all over the world; 3) engineering (20.64%) is the hottest research direction, and takes up about one-fifth of the total publications; 4) the Journal of the American Medical Association and The New England Journal of Medicine are among the two journals that are the most highly cited, followed by Science and The Lancet; and 5) keywords of the medical device include in vitro, quality-of-life, outcomes, management, mortality, depression, and so on. With the help of mapping knowledge, we dig out some hot topics of medical devices and provide more information through trend analysis, and we discover that our findings are related to previous research and further research can enlarge the number of records and optimize the algorithm. We provide a systematic approach for researchers to keep abreast of the development and state of the research of medical devices.

f2-mder-7-357: The percentage of publications by country, 2004–2013.

Mentions: Figure 2 illustrates the percentages of publications across countries from 2004 to 2013. The USA (38.49%) takes up more than a third of the total at the top of the list. The next two significant countries are Germany and England, which are 8.42% and 6.05%, respectively. People’s Republic of China (3.97%) only ranks in eighth place, and drops behind Japan (4.30%). The large amount of USA literature is closely related to strong economic strength and high research investment; besides, some of the world’s leading countries are European. By contrast, People’s Republic of China desperately needs to increase the invested funds for scientific research in the field of medical devices and instruments to vitalize the development of the domestic medical device industry.
