Overall, medical devices cover a vast range of products used to monitor, prevent, and treat various ailments. Medical devices cover medical instrumentation (electronics), mechanical devices, and combination devices. Combination devices have two or more chemical, electrical, mechanical, pharmaceutical, or biological components. Medical devices cover multiple uses, including implantable devices, devices used during surgical procedures, and non-implantable devices used at home by patients. Medical device creation and usage have risen along with the rise in digital technology. However, standards for many medical devices are less strict than for medications. Consequently, novel medical devices are adopted within healthcare systems without adequate assessment of their cost-effectiveness or patient usage benefits. Indeed, the introduction of a novel medical device comes with a host of risks for healthcare facilities. These risks include insufficient proof of efficacy, learning curve effects, dynamic pricing, and transferability. When designing a medical device, information on the best training practices for the device and how that device compares to gold standards for treatment, preventative care, or patient monitoring is influential in adopting the use of your medical device. Further, during medical device development, ensure you choose a contract testing organization that can support you with appropriate biocompatibility and package integrity testing for your unique medical device needs.
