The present invention relates to a medical device. In particular, the present invention concerns a medical device which can be detected by means of magnetic resonance imaging (MRI).

Fibers sized with a coating of amorphous polyetherketoneketone are useful in the preparation of reinforced polymers having improved properties, wherein the amorphous polyetherketoneketone can improve the compatibility of the fibers with the polymeric matrix.

The present invention relates to a medical device. In particular, the present invention concerns a medical device which can be detected by means of magnetic resonance imaging (MRI).

A fiber reinforced composite material containing a polymeric resin matrix reinforced by fabrics consisting of co-mingled glass/carbon yarns for a doctor blade.

The invention is concerned with filled multifilament yarn according to the present invention whereby the filler ratio, , in the yarn is greater than 0.004 times the IV of the UHMWPE present in the multifilament yarn (IV.sup.Y.sub.UH), i.e. 0.004 g/dL*IVy.sub.H, and whereby the tenacity (TEN, in cN/dtex) of the filled multifilament yarn is such that TENIV.sup.Y.sub.UH*(1.5-3.25*), or whereby the tenacity of a filled monofilament in the yarn is tenIV.sup.Y.sub.UH*(2-4.35*.sub.X). The invention is further concerned with a method to manufacture said multifilament yarn and articles comprising said multifilament yarn.
