MDSAP and a MDSAP Audit Experience

The Medical Device Single Audit Program (MDSAP) is a new medical device auditing plan with potential for several advantages. This discussion addresses an actual MDSAP audit experience and demonstrates how the organization dealt with its complexities. The MDSAP program is described including country involvements. Audit personnel and experiences are discussed. Example documents are described. An example hourly schedule is presented. The observation rating system is described and example audit finding are presented. Differences compared to and FDA audit are considered. The MDSAP is the biggest change in medical device regulations since the introduction of the European MDD in the 1990’s. Time will tell whether MDSAP will ultimately lead to a better quality in design, manufacturing, and regulatory control.

Building Better Bonds

Until recently, there was little up-to-date research about adhesives that could be used with Eastman Tritan™ copolyester. By collaborating with Henkel Corporation, whose LOCTITE® adhesive continues to be tested at the industry’s most comprehensive ISO 10993 biocompatibility standards, Eastman was able to determine which combination of resins and adhesives could help optimize a manufacturer’s assembly process. Results proved that Tritan, together with LOCTITE® adhesives, provides improved process efficiency for a wide range of medical devices.

Creating the Future: Wearable Bands Offer Continuous Blood-Pressure Measurement

The pneumatic cuff, a device traditionally used to measure blood pressure, has had a prominent place in doctors' offices for more than a century. As part of a year-long fellowship at Northwestern University, two clinicians and two engineers teamed up to develop a new way of measuring blood pressure: cuffless, wearable wristbands.

Silver Bullet Against MRSA: Silver Ion-coated Devices

Methicillin-resistant Staphylococcus aureus (MRSA) infections are caused by a type of staph bacteria that has become resistant to the antibiotics used to treat ordinary staph infections. The rise of MRSA infections is limiting the treatment options for physicians and surgeons. Now, an international team of researchers, led by Elizabeth Loboa, dean of the University of Missouri College of Engineering, has used silver ion-coated scaffolds, or biomaterials that are created to hold stem cells, which slow the spread of or kill MRSA while regenerating new bone. Scientists feel that the biodegradable and biocompatible scaffolds could be the first step in the fight against MRSA in patients.

Devices Enhance Treatment for Cardiovascular Problems

Two medical devices approved by the FDA within the past year – a miniaturized pacemaker that doesn't have any wires and a coronary stent that gradually dissolves in the body – are showing promise as effective treatments for people with certain heart and vascular problems.

The new pacemaker, called the Micra Transcatheter Pacing System, is just an inch long, about one-tenth the size of traditional devices, and is the first "leadless" pacemaker to be approved for use in the United States.

Study Looks at Powering Medical Implants With Solar Cells

The notion of using solar cells placed under the skin to continuously recharge implanted electronic medical devices is a viable one. Swiss researchers have done the math and found that a 3.6 square centimeter solar cell is all that is needed to generate enough power during winter and summer to power a typical pacemaker. The study is the first to provide real-life data about the potential of using solar cells to power devices such as pacemakers and deep brain stimulators. According to lead author Lukas Bereuter of Bern University Hospital and the University of Bern in Switzerland, wearing power-generating solar cells under the skin will one day save patients the discomfort of having to continuously undergo procedures to change the batteries of such life-saving devices.

G-putty Innovation for Medical Devices and Diagnostics

Graphene Flagship researchers from Trinity College Dublin, working with the National Graphene Institute (NGI) at the University of Manchester, have used graphene to make the novelty children's material Silly Putty® (polysilicone) conduct electricity. Using this conductive polymer, they found that they were able to create extremely sensitive sensors.
