A61L29/00

Materials for catheters or for coating catheters (shape or structure of catheters A61M 25/00) [4]

Note(s) When classifying in group A61L 29/00, classification is also made in A61L 33/00 if the materials used are antithrombogenic.[7] In groups A61L 29/02-A61L 29/12, the last place priority rule is applied, i.e. at each hierarchical level, in the absence of an indication to the contrary, classification is made in the last appropriate place. [7]When classifying in groups A61L 29/02-A61L 29/12, classification is also made in group A61L 29/14 if the use of materials characterised by their function or physical properties is of interest.
