i.
When attempting vessel access, watch for the following:
•
Anterior vessel wall indenting (once the puncture occurs the vessel will return to normal shape)
•
Blood return in the device
•
Needle reflection (flash of the needle tip) on the ultrasound image
Note:
When the virtual needle tip passes the ultrasound plane the color of the virtual needle shaft will change
but still represents the virtual needle tip position.

In-Plane
Ultrasound Guided Insertion Using Pinpoint™ GT Needle Technology.
a.
When the system is calibrated, retrieve the Pinpoint™ GT Safety Introducer Needle and move the Needle
toward the side of the probe at a 45° angle until the Pinpoint™ GT Needle Technology virtual needle image
appears on the ultrasound image (refer to figure at right). Confirm the virtual needle image motion on the
ultrasound display mirrors actual needle movement
Caution:
If needle tracking is not functioning properly, discontinue
use of Pinpoint™ GT Needle Technology.
b.
Center the virtual needle image in the In-Plane box may
modifying the position and angle of the needle. Confirm needle
alignment with the intended target structure.
Note:
In-Plane Mode does not have a Point of Intersection
Circle. When the needle trajectory is centered in the In-
Plane Box, the box will turn green.
c.
While maintaining the desired needle angle, insert the
Pinpoint™ GT Safety Introducer Needle into the skin. Refer to
Pinpoint™ GT Safety Introducer Needle IFU for more
information
•
To maintain accuracy, use a
‘light touch,’
(which is defined
as minimal stress, force, or pressure on the needle during
insertion)
Note:
Once the needle enters the skin, it may be helpful to
release pressure on the needle hub to assess Pinpoint™
GT Needle Technology System alignment with the
structure of interest.
Caution:
During insertion, use a light touch to prevent needle deflection and/or bending. Needle deflection and/or
needle bending may reduce needle tracking accuracy.
Caution:
To ensure accuracy, do not apply force or pressure that may leverage the needle. This may result in
needle deflection, bending, or altering needle trajectory.
d.
Without leveraging the needle, proceed with insertion – watch needle advancement onscreen. The solid
yellow line represents the needle shaft and tip.
e.
During advancement, maintain the needle trajectory in the center of the intended target structure. Maintain
the needle so that the trajectory is centered in the In-Plane Box and the In-Plane Box is green.

Anterior vessel wall indenting (once the puncture occurs the vessel will return to normal shape)
