What is a micropuncture set?
A micropuncture set is used to obtain vascular access. It contains a 21-gauge single-wall needle, an 0.018-inch wire, and a dilator. The dilator is tapered to the 0.018-inch wire to allow for easy placement. The inner portion of the dilator can be removed along with the wire to allow the dilator to accept a standard 0.035-inch wire. This set can be used as an alternative to double-wall needles. Some prefer this set for gaining access for thrombolysis because it uses the single-wall technique.
