Hello All,
I've been working on the MDCG 2020-5 Clinical Evaluation - Equivalence in an attempt to find an appropriate work around about with respect to MDR, Annex XIV Part A(3) : Biological Characteristics :
" the device uses the
SAME materials... in contact with the same human tissues...."
This is for a new device going to market for the first time under MDR, class IIa.
The intention is to establish "equivalence" and not "similar" with a device followed by appropriate literature support, so :
- both devices are in contact with the skin (intact)
- both devices are in contact with the same human tissues
- both devices are "for a similar kind & duration" of contact..
The patient contact is silicon for our device, obviously we now the exact details, etc etc.
However, the sticking point is that we don't know what the "equivalent" device contact material is, we suspect its silicon... it looks a feels its, unfortunately it is not mentioned anywhere in the technical details available for their device...
So, the only "common aspect" we can be certain of it that both our device and the "equivalent" device are conform to ISO10993-1, -5, -10.
I strongly believe that we can demonstrate that silicon is a well established material, in the medical field & such use cannot have an impact on "safety & clinical performance".
I have yet to approach our Notified Body about this, but I wonder how anyone else have managed this... As I can believe there is going to be a major problem for many devices trying to push through the Clinical Evaluation using "equivalent" device.... but not having proof of the "same materials".
Any experience anyone ?
Thanks
Tim
