I refer to the letter by Dr Trewinnard1 in the July 2017 edition of this journal regarding safety concerns with the TT380 intrauterine device (IUD).

In my experience, the inserter tube of the TT380 Slimline device is not malleable enough to shape into a semicircular form for insertion of the IUD into a retroverted or acutely anteverted uterus. Attempts to persist with shaping the inserter will result in kinking of the inserter tube with occlusion of its lumen and perforation of the tube by the introducer rod if insertion is attempted, as experienced by Dr Trewinnard.

Failure to shape the inserter tube will thus result in a failed IUD insertion in the aforementioned uterine positions and worse, possible uterine perforation.

I have stopped using the TT380 Slimline for the past 6 years because of this problem, and now only use the NovaT 380 (Bayer Pharma AG) and T-Safe 380 (Mona Lisa N.V.) systems.

I look forward to the improved redesigned TT380 Slimline.2
