Vascular Access System Provides Auditory Ultrasound-Guided Feedback


January 11, 2011

The SmartNeedle Vascular Access System, by Vascular Solutions, consists of a hand-held monitor and one-time use needles designed to provide auditory ultrasound-guided access during catheterization procedures. It is available in the United States and Europe.

The Doppler guided needle access system was acquired from Escalon Medical in May 2010.

The reusable, hand-held monitor transmits a continuous wave Doppler signal, providing continuous auditory feedback to help locate and access the artery or vein quickly. If desired, the monitor can be covered with a disposable sterile bag for use in the sterile field.

Sterile, single-use needles range from 18 to 24 gage, with bare tip and sheathed IV options. Bare-tipped needles are available in 18, 20 and 22 gage sizes, and consist of a detachable Doppler probe that is housed within the lumen of a standard sized introducer needle. IV sheathed needles, used when attempting to access a vessel with the intent of leaving a small catheter in place, are available in 20, 22, 24 and 26 gage sizes.
