Bioresorbable

Capable, in an intended biological context, of degradation followed by biological processing, absorption or clearance of constituent products; usage varies by discipline.

Biodegradable

Susceptible to breakdown through chemical or biological processes. Breakdown alone does not necessarily demonstrate complete biological resorption.

Bioabsorbable

Often used similarly to bioresorbable in medical-device contexts, but interpretation depends on product labeling and biological fate.

Hydrolysis

Chemical cleavage by water; important in degradation of many aliphatic polyester medical materials.

Erosion

Loss of material from a device, which may occur after significant molecular-weight decline.

Functional lifetime

The period during which a medical device continues to meet the specific performance requirements of its intended use.

PLGA

Poly(lactic-co-glycolic acid), a lactide-glycolide copolymer family used in various biomedical material architectures.

Tissue scaffold

A matrix or framework designed to temporarily support tissue organization or repair.

Transient electronics

Electronic systems intended to perform for a finite time with selected degradable or resorbable components.

These definitions are educational; regulatory terminology must be interpreted in the context of the exact device and jurisdiction.

DIRECT ANSWERS

Questions worth asking.

Is absorbable the same as bioresorbable?

The terms overlap in medical-device use but their exact interpretation depends on the material, regulatory context and biological fate.
