Introduced: January 1995

Full Title

Full titles differ between systems:

IPC:

Tubes, tube connectors, tube couplings, valves, access sites or the like, specially adapted for medical use > Valves or arrangement of valves

CPC:

Tubes, tube connectors, tube couplings, valves, access sites or the like, specially adapted for medical use (for respiratory devices, e.g. tracheal tubes A61M16/00; artificial heart valves A61F2/24) > Valves or arrangement of valves

CPC subdivides this area 3x more granularly than IPC with 6 additional codes.

6 codes are CPC-only extensions.

Note: 2 CPC extensions are marked as secondary classification only.

IPC defines codes here since 1995.
