Ultrashort Laser Texturing for Tuning Surface Morphology and Degradation Behavior of the Biodegradable Fe–20Mn Alloy for Temporary Implants

Abstract

Biodegradable metallic alloys are promising materials for the development of temporary medical implants, including cardiovascular and orthopedic devices. The present work explores the surface modification of a biodegradable Fe–20Mn alloy by means of ultrashort laser texturing and the correlation between the laser‐induced surface morphology and the degradation behavior. In detail, the effect of different processing parameters on surface morphology is explored and compared with the unprocessed surface. It is found that laser texturing can tune the degradation rate, selectively inducing positive (+29%) or negative (−31%) change with respect to the untreated surface.

Image-Guided Surgical and Pharmacotherapeutic Routines as Part of Diligent Medical Treatment

“…In fact, all of the implants described in the last paragraph ar made from non-biodegradable materials and require the disposal of SI. Two next chal lenges should be acknowledged: The first concerns the facilitation of self-contained im planted DD systems addressing simple and spatially homogeneous problems using con stant drug release and biodegradable structures that facilitate disposal of implanted sys tems [60][61][62][63][64][65][66][67][68][69][70][71]. The second concerns the treatment of spatially complicated cases requiring non-uniform DD, focusing only on diseased areas and avoiding healthy areas.…”

“…These structures employ RDD for nearby tissue containing a specified area. Implanted treatments designate at best the practice of biodegradable ingredients and at least materials compatible with the treatment [60][61][62][63][64][65][66][67][68][69][70][71], as well as wireless operated implanted actuations.…”

“…These concern artefacts of biodegradable magnesium-based im sessment of implant-related pain and dysfunction, cochlear implant positioni imaging quality, adverse local tissue reactions near metal implants after total plasty, metal artefact reduction sequences for a piezoelectric bone conductio image quality and artifact reduction of a cochlear implant, MRI in patients w implantable electronic devices, and MRI artifacts caused by auditory implants treatment structures might manage confined conduct MI-imbedded equipm structures employ RDD for nearby tissue containing a specified area.

Assessment of a Functional Electromagnetic Compatibility Analysis of Near-Body Medical Devices Subject to Electromagnetic Field Perturbation

“…Recent advances in the field of biocompatible and biodegradable materials [62][63][64][65][66][67][68][69][70][71][72][73] have enabled the development of implantable static passive tools enabling diagnoses and prediction via mini-sensors, thereby dramatically improving the value and efficiency of patient healthcare [74][75][76][77][78]. Other static but active implanted devices are proposed to stimulate or trigger an organ, as pumps, neuro-stimulators or pacemakers [79][80][81][82][83].…”

Inherent Antibacterial Properties of Biodegradable FeMnC(Cu) Alloys for Implant Application

“…However, as those materials should release Cu ions as they degrade, lower Cu contents would be sufficient. Besides Mg-based , and Zn-based, Fe-based alloys − are also widely investigated for the use as temporary implant material with high potential for future clinical application. Regarding degradable Fe-based implant materials, only a few studies investigate the alloying with Cu.…”
