WARNING
-
The following IPC groups are not used in the CPC system. Subject matter covered by these groups is classified in the following CPC groups:

A61L33/10 covered by A61L 33/0011
A61L33/14 covered by A61L 33/0011
A61L33/16 covered by A61L 33/0047

IPC7 groups A61L 2/07 and subgroups, and A61L 9/012 to A61L 9/014 might be incomplete as relevant documents might still be classified in the hierarchical higher groups

NOTE
-
In groups A61L 27/02 to A61L 27/48 , in the absence of an indication to the contrary, classification is made in the last appropriate place

When classifying in groups A61L 27/02 to A61L 27/48 , classification is also made in groups A61L 27/50 to A61L 27/60 if the use of materials characterised by their function or physical properties is of interest

When classifying in group A61L 27/00 , classification is also made in A61L 33/00 if the materials used are antithrombogenic

In group A61L 27/00 , the use of specific polymers is indicated using the relevant classification symbols of subclass C08L in the second position of the combination set, e.g. prosthesis based on polyvinylchloride A61L 27/16 , C08L 27/06

In groups A61L 33/0076 to A61L 33/0094 and A61L 33/02 to A61L 33/122, in the absence of an indication to the contrary, classification is made in the last appropriate place

When classifying in groups A61L 33/02 to A61L 33/122, classification is also made in group A61L 33/0005 if of interest

In group A61L 33/00 , the use of specific polymers is indicated using the relevant classification symbols of subclass C08L int the second position of the combination set, e.g. antithrombogenic treatment with the help of polyvinylchloride A61L 33/064, C08L 27/06
