WEBINAR: Accelerated Medical Device Testing for Fatigue Failure: Current Technology and Challenges

Fatigue failure is a possible failure mode for any product that experiences cyclic loading. Although it is a common concern in product design, fatigue failure is particularly insidious in implantable medical devices where a fatigue fracture may have lethal clinical consequences. Learn more in this webinar featuring Thomas Secord, University of St. Thomas, and previously of Medtronic. Dr. Secord's work has addressed many aspects of structural design, accelerated testing, and regulatory considerations for implantable devices.

Embedded Device Stimulates Nerve Recovery, Then Absorbed by Body

Engineers develop the first bioelectronic medicine—an implantable device that stimulates nerve regeneration with electrical pulses. Once the nerve heals, the device disintegrates and the body absorbs it without toxic side effects.
