Da, predilate ne postoji (according to tfd.com). Mislim da je pre-dilate, to je:
v. dilate, dilated, dilating, dilates
v.tr.
To make wider or larger; cause to expand.
Kao što ste Vi rekli, uvećati, proširiti. Odnosno, zbog ovoga -pre, prethodno uvećati, proširiti. Mirin primer - pre-dilatation je takođe tačan - (imenica) proširenje, uvećanje.

Mislim da je greška, da bi trebalo pre-dilatate:

Improved design, profile and flexibility of the currently available stents now permit to deliver the stent without pre-dilatation.
