# 510(k) Summary
## Site~Rite 3 Ultrasound Scanner
Common/Classification Name: Ultrasonic Pulsed Echo Imaging System, 21 CFR 892.1560
> Dymax Corporation 271 Kappa Drive Pittsburgh, PA 15238
Contact: Charles Morreale: Prepared: October 18, 1999
### LEGALLY MARKETED PREDICATE DEVICES A.
The Site~Rite 3 Ultrasound Scanner is substantially equivalent to the Site~Rite 2 Ultrasound Scanner (cleared as the Dymax Plus 1 Scanner, K862127) and the Dymax Plus 1 (cleared as the Dymax TM18, K850478).
## DEVICE DESCRIPTION B.
The Site-Rite 3 pulsed echo ultrasound system is a lightweight, lowoutput, portable, real-time, B-mode, ultrasound scanner designed primarily to assist physicians in gaining vascular access to major veins and arteries. It is a unique scanner that offers high resolution imaging to the depth of 18 cm. Site-Rite is portable and thus easy to use at the bedside and in a variety of clinical scenarios: intensive care units, emergency rooms, operating rooms, angiography suites, catheterization laboratories, etc.
The Site-Rite 3 ultrasound scanner can be operated on battery or AC power. It utilizes only proprietary probes manufactured and currently marketed by Dymax, with frequencies ranging from 3.5 MHz to 9.0 MHz. Image depth depends on the choice of probe and ranges from a minimum of 0.5 cm with the 9.0 MHz probe to a maximum of 18 cm with the 3.5 MHz probe.
The disposable items, supplied in sterile packs, are currently marketed products.
#### C. INTENDED USE
The Site~Rite 3 ultrasound system with associated probes and accessories provide ultrasound imaging of vascular structures, various organs, and structures of the body. Ultrasound guidance for placement of
9o
{1}------------------------------------------------
needles and catheters in these structures or organs may also be performed. The ultrasound guidance may occur either intraoperatively or percutaneously.
The Site~Rite 3 is not intended for opthalmic applications.
## D. SUBSTANTIAL EQUIVALENCE SUMMARY
The Site~Rite 3 Ultrasound Scanner has similar, but not identical indications for use as the predicate devices. The Site~Rite 3 indications add specific vein access to the already cleared general vascular access indication. However, this difference clearly does not change the intended use.
The technological characteristics are somewhat different from the predicate devices since the electronics design of the Site~Rite 3 has included digital electronic technology, whereas the predicate devices were completely analog in nature. The transducers, however, are unchanged from the currently marketed products.
The differences in technological characteristics do not raise new types of questions of safety and effectiveness. There are standard methods for accessing safety and performance, primarily through the methods spelled out in the FDA quidance. Performance data are presented in the 510(k) and these data demonstrate equivalence.
## E. TECHNOLOGICAL CHARACTERISTICS
The primary difference in the Site~Rite 3 and the Site~Rite 2 is that the older Site~Rite 2 has a generator with an analog design, whereas the Site~Rite 3 is digital in design.
## ட் TESTING
Testing was carried out to address electrical safety, electromagnetic emissions, and acoustic output. - Data from this testing demonstrate equivalence with the predicate devices.
Clinical studies carried out using the Site~Rite 2 device, which uses the same transducers and image processing algorithms, has shown the usefulness of the Site~Rite for needle placement in a number of different vascular and non-vascular applications. These studies are summarized and reports are included in the 510(k).
{2}------------------------------------------------
## G. CONCLUSIONS
This pre-market submission has demonstrated Substantial Equivalence as defined and understood in the Federal Food Drug and Cosmetic Act and various guidance documents issued by the Center for Devices and Radiological Health.
