English to Spanish Other Medical: Instruments

Here's what I've found, but I need translations, help!

The term "echo" refers to a surface treatment done to a needle to make it easily visualized using ultrasound. A lot of clinicians will make an initial stick with an echo needle and verify placement with ultrasound.

The "stiffened dilator" is part of an introducer system that allows the clinician access to a vessel.

These terms are on a product label.
