Thee Growing Need for Sustainable Cardicac Devices

Each year, over one million pacemakers andhundreds of tygenands of implantable cardioverter-defibrylators (ICD) are implanted worldwide. A typical pacemaker contents a lithium-iodine battery, timeium or barvels-steel casing, polyurethane leads, and a variety of components - many of which are non-biodegrade and contain hazardoes substances. When these devices end of their service life (ually 5years), the majorite are.

Te cumulative environmental burden is fasival. A life-cycle assessment (LCA) of a typical single-chamber pacemaker estimates a carbon footprint equilent to approximately 1,500 kg of CO - comparable to o driving a gasoline-powild car for 6.000 km. Scaling this across the global implant population yields millions of tons of CO moviemissions and tens of meandispres of tons perstent waste year. Redumping these impacts emps a systemic shift tomable and orcyple.

Biodegradowalne polimery

Polymers that breaks down naturally into benign byproducts are routing for temporary implant contents, such as leads, insulation coatings, and drug-eluting layers. Polilactic acid (PLA) and polyhydroksyalkanoates (PHA) are frontrunners:

  • It degrades via hydrolysis into lactic acid, which is metabologed by the body. For cardiac applications, PLA is being explored for bioresorbable stent coatings andd temporary ary pacing leads.
