Mini Step™ access system

Bladeless trocars

Mini Step™ access system

The Mini Step™ access system is intended for abdominal and thoracic procedures and offers dilatation access to cavities for diagnostic and operative purposes.

Description

The Mini Step™ access system incorporates Step™ radial dilation technology with a truly bladeless obturator. The defect size from radially dilating trocars has been shown to be smaller than bladed trocars.†,‡,§,1

Measured defect size of 5.4 × 3.8 mm was significantly smaller than linear bladed trocars (10.5 × 6.1 mm, P < .001).

Functional defect size as measured by bead technique of 13.12 ± 0.35 mm was significantly smaller than linear bladed trocars (14.12 ± 0.64 mm, P < .001).
