Physician entrepreneurs are key contributors to new medical devices

New rules on financial relationships might slow medical innovation, suggests study in Medical Care

2013-04-17
(Press-News.org) Philadelphia, Pa. (April 16, 2013) - Startup companies founded by physician entrepreneurs are an important source of patents used in developing innovative new medical devices, suggests a study in the May issue of Medical Care. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

"Device manufacturers gain more from the patents of physician-founded firms than from those of non-physician-founded firms in their subsequent invention and innovation efforts," according to the study by Sheryl Winston Smith, PhD, and Andrew Sfekas, PhD, of the Fox School of Business at Temple University, Philadelphia. They raise concern that too-strict policies on financial relationships with physicians could hinder innovation in the medical device industry.

Doctors Make Key Contributions to New Medical Devices

The researchers analyzed a total 170 premarket approval applications (PMAs) filed by four major medical device companies between 1978 and 2007. The study also included data on patent applications from 119 startup companies—all of which had received investment dollars from the medical device industry. All four device makers had active corporate venture capital programs during the study period.

Using a sophisticated text-matching algorithm, Drs Smith and Sfekas assessed the information contributed by physician-founded startup companies versus non-physician-founded startups. The study focused on class III medical devices: the highest-risk classification, requiring significant testing to prove device safety and effectiveness.

The two groups of startups produced roughly the same number of patents. However, patents from physician-founded startup companies were cited more heavily in the PMAs, compared to those from non-physician-startups. "On average physician-founded companies account for eleven percent of the information in PMAs, compared to four percent from non-physician-founded companies," Drs Smith and Sfekas write.

Two-thirds of PMAs overlapped by at least ten percent with patents from physician-founded startups, compared to about one-fourth with patents from non-physician startups. Of PMAs with at least twenty percent information from external sources, about 80 percent included information from physician-founded startups versus 40 percent from non-physician-funded startups.

Could New Rules Hinder Device Innovation?

Facing intense pressure for constant innovation, the medical device industry relies on corporate venture capital as a source of new ideas and patents. By assessing information overlap between PMAs and patents, the study algorithm helps in identifying which patents are more versus less important in developing successful new products. The results suggest that startup companies founded by physician entrepreneurs make uniquely important contributions to the development of new medical devices.

Historically, physicians have played a central role in the development process. Various types of financial relationships between physicians and medical device manufacturers are common, but are increasingly subject to policies regarding disclosure of potential conflicts of interest. These include the "sunshine provisions" of the Patient Protection and Affordable Care Act, under which drug and medical device manufacturers are required to report any financial relationships they have with physicians.

The new findings raise concerns that, if conflict of interest rules are too tight, they could have the unintended effect of slowing the pace of new advances in the medical device industry. Drs Smith and Sfekas write, "[R]estrictions on financial relationships between providers and industry, while potentially improving patients' trust, may result in reduced medical innovation if physicians found fewer startups or if incumbent firms reduce investments in physician-founded startups."

Softening steel problem expands computer model applications

2013-04-17
ALBUQUERQUE, N.M. — Sandia National Laboratories researchers Lisa Deibler and Arthur Brown had a ready-made problem for their computer modeling work when they partnered with the National Nuclear Security Administration's Kansas City Plant to improve stainless steel tubing that was too hard to meet nuclear weapon requirements. When steel is too hard it becomes brittle, so the plant ended up getting new tubing. However, Deibler said KCP needed a backup in case it couldn't find replacements in time to meet deadlines. Sandia's modeling, coupled with experiments, allowed ...

NASA imagery shows wind shear hammering Cyclone Imelda

2013-04-17
Cyclone Imelda has lost both her punch and her hurricane status as the storm moved into an area of higher wind shear and cooler waters in the Southern Indian Ocean. NASA's Aqua satellite provided an image of Imelda that showed wind shear that has been hammering the storm, had pushed the bulk of the storm's precipitation southeast of the center. Wind shear at higher levels has increased to as high as 30 knots (34.5 mph/55.5 kph), according to upper level analysis of the atmosphere that was conducted by the Joint Typhoon Warning Center. That stronger wind shear is weakening ...

Small in size, big on power: New microbatteries the most powerful yet

2013-04-17
CHAMPAIGN, Ill. — Though they be but little, they are fierce. The most powerful batteries on the planet are only a few millimeters in size, yet they pack such a punch that a driver could use a cellphone powered by these batteries to jump-start a dead car battery – and then recharge the phone in the blink of an eye. Developed by researchers at the University of Illinois at Urbana-Champaign, the new microbatteries out-power even the best supercapacitors and could drive new applications in radio communications and compact electronics. Led by William P. King, the Bliss ...

Plasma device developed at MU could revolutionize energy generation and storage

2013-04-17
University of Missouri engineer Randy Curry and his team have developed a method of creating and controlling plasma that could revolutionize American energy generation and storage. Besides liquid, gas and solid, matter has a fourth state, known as plasma. Fire and lightning are familiar forms of plasma. Life on Earth depends on the energy emitted by plasma produced during fusion reactions within the sun. However, Curry warns that without federal funding of basic research, America will lose the race to develop new plasma energy technologies. The basic research program was ...

Dying supergiant stars implicated in hours-long gamma-ray bursts

2013-04-17
Three unusually long-lasting stellar explosions discovered by NASA's Swift satellite represent a previously unrecognized class of gamma-ray bursts (GRBs). Two international teams of astronomers studying these events conclude that they likely arose from the catastrophic death of supergiant stars hundreds of times larger than the sun. VIDEO: GRB 101225A, better known as the "Christmas burst, " was an unusually long-lasting gamma-ray burst. Because its distance ...

NASA's Wind mission encounters 'SLAMS' waves

2013-04-17
As Earth moves around the sun, it travels surrounded by a giant bubble created by its own magnetic fields, called the magnetosphere. As the magnetosphere plows through space, it sets up a standing bow wave or bow shock, much like that in front of a moving ship. Just in front of this bow wave lies a complex, turbulent system called the foreshock. Conditions in the foreshock change in response to solar particles streaming in from the sun, moving magnetic fields and a host of waves, some fast, some slow, sweeping through the region. To tease out what happens at that boundary ...

Multicenter study confirms low testosterone in 84 percent of lung cancer patients taking crizotinib

2013-04-17
A previous study by the University of Colorado Cancer Center reported the common side effect of low testosterone in men treated with the recently approved lung cancer agent, crizotinib. A new study published this week in the journal Cancer confirms this finding in a multi-national sample, details the mechanism of reduced testosterone, and provides promising preliminary evidence that widely available hormone replacement therapies can alleviate this side effect in many patients. "This was a wonderful collaboration between multiple centers confirming a side effect that had ...

Memory, the adolescent brain and lying: The limits of neuroscientific evidence in the law

2013-04-17
April 16, 2013 – San Francisco – Brain scans are increasingly able to reveal whether or not you believe you remember some person or event in your life. In a new study presented at a cognitive neuroscience meeting today, researchers used fMRI brain scans to detect whether a person recognized scenes from their own lives, as captured in some 45,000 images by digital cameras. The study is seeking to test the capabilities and limits of brain-based technology for detecting memories, a technique being considered for use in legal settings. "The advancement and falling costs ...

Experiment shows why some stress is good for you

2013-04-17
Overworked and stressed out? Look on the bright side. Some stress is good for you. "You always think about stress as a really bad thing, but it's not," said Daniela Kaufer, associate professor of integrative biology at the University of California, Berkeley. "Some amounts of stress are good to push you just to the level of optimal alertness, behavioral and cognitive performance." New research by Kaufer and UC Berkeley post-doctoral fellow Elizabeth Kirby has uncovered exactly how acute stress – short-lived, not chronic – primes the brain for improved performance. In ...
