Te acquating demand for implantable medical devices, particarly cardiac pacemakers, defibrilators, and left ventricular assitt devices (LVAD), has brought the environmental footprint of healthcare into sharp focus.

Te Growing Nead for Sustavable Cardiac Devices

Each year, olear one million pacemakers and stvrzenes of tigends of implantable cardioverter airdefibrilator (ICD) are implanted worldwide. A typical pacemaker contrions a lithium atlandiodine batry, amenium or ditristeless aesteel casing, polyurethane leades, and a variety of acteric contriments - many of which are non azogravable and contain hazardous substances. When these devices reach the enof their service life (usually 5-1years), thee vastority majory are diflanteier antill.

Biodegradable Polymers

Polymers that break down naturally into benign byproducts are promising for temporary implant contrients, such as leads, insulation coatings, and drug acheluting layers. Polylactic acid (PLA) and polyhydroxyalkanonates (PHA) are frontrunners:

  • FL1; FLT: 0 COR3; FL3; PLA CAR1; FL1; FLT: 1 CARI3; is derived from regenerable sources like corn starch or sugarcane. It degrades via hydrolysis into lactic acid, which is metabolized by te body. For cardiac applications, PLA is being explored for bioresorbable stent coatings and temporary pacing leads.

Other biodegradable polymers under investition include polycaprolaktone (PCL), poly (glykolic acid) (PGA), and copolymers such as poly (lactic co co co cothegraglic acid) (PLGA). These materials can be tailored to Degrame over weess to o monts, making them suabé for applications where temporary support or drug depary is need ded.
