2. GENERAL INFORMATION - SYSTEM OVERVIEW
2.1 Description of the System
The LySonix 3000
® with PulseSelect ™
is a system of electromechanical components designed to
ultrasonically fragment and aspirate a broad range of soft tissue. The system includes a Generator
that produces a 22.5 kHz electrical signal and feeds that signal via the cable to a piezoelectric
crystal stack mounted in the autoclavable Operating Handpiece. The crystal stack converts the
electrical signal to mechanical vibration at that same frequency. This ultrasonic vibration is
amplified as it traverses the length of the titanium Probe attached to the front of the Operating
Handpiece. The Operating Handpiece and Probe have a central aspiration channel for use with an
aspiration system to remove fragmented material and waste liquids.
2.2 Concept and Principles of Operation
The LySonix 3000
® with PulseSelect ™
uses ultrasound, or sound waves for fragmentation of soft
tissues. Unlike standard cutting or Opto-Thermal systems, the LySonix 3000® with PulseSelect
™
offers precise control of tissue ablation due to the controlled ultrasound field generated. This
precise control allows the surgeon to perform traumatic fragmentation and removal of tumors and
other biomass with minimal disturbance to surrounding tissue structure.
The LySonix 3000
® with PulseSelect ™
ultrasonically fragments living and necrotic tissue by a
process known as cavitation. Cavitation is basically the formation and collapse of microscopic
bubbles which are produced at the tip of the titanium Probe mounted on the Handpiece. The
Generator unit (Power Supply) feeds a 22.5kHz (22,500 cycles per second) electrical signal to
piezoelectric crystals mounted in the Handpiece. The active elements of the Handpiece then vibrate
at that same 22.5 kHz frequency. The vibration is amplified by a titanium Front Driver integral to
the Handpiece and further amplified down the Probe (or Horn). The distal end of the Probe (the
Radiating Face) vibrates at this high amplitude and at the same frequency. When placed in a liquid,
the vibrating probe tip causes microscopic bubbles to grow and then collapse with great energy
intensity, thus causing the tissue directly in front of the Probe to be liquefied or fragment.

40-OM-0002 Page 13 of 43 Rev B
2.3 Functional Components of the System
2.3.1. Generator
The Generator supplies a 22.5 kHz electrical signal to the Handpiece. A feedback circuit tracks
frequency changes in the Probe caused by load and temperature changes, and maintains maximum
electrical efficiency at all times.
In addition, the Generator incorporates an automatic gain control that maintains the amplitude
selected by the user. As the Probe meets resistance, the Generator will automatically supply greater
power (wattage) to the Handpiece, thereby keeping the amplitude constant. This is analogous to
cruise control on an automobile, which will maintain the car's speed as the road conditions vary.
Amplitude, which is the distance the Probe moves out from rest and back in each cycle, determines
the extent of tissue disruption. The Generator has a self-limiting feature that prevents damaging
overload. Amplitude Setting is indicated by an LED bar graph display on the front panel.
The PulseSelect
™
Feature allows the user to initiate a Pulsed Wave Output as opposed to having a
Continuous Wave Output. A rocker switch allows the user to change modes while a rotary knob
sets the Pulse Duration of the Pulsed Wave Output.
Main power is controlled by the Main Power switch on the back panel of the Generator. Ultrasonic
power is controlled by the Ultrasonic Enable switch on the front panel and by a footswitch
connected to the rear panel of the generator.
An elapsed time meter records cumulative ultrasonic on-time during a procedure. A reset button
resets the elapsed time meter to zero. A Mechanical Limit Detector may detect breakage along the
Probe, Handpiece failure, or system overload. These faults will activate an indicator light and an
audible alarm. An Electrical Fault Detector detects an open ground wire and short or break in an
output circuit. These faults will activate an indicator light as well as an audible alarm. Both fault
alarms will deactivate the ultrasonic output of the generator.
2.3.2. Handpiece
The handle section of the Handpiece houses the piezoelectric crystals that transform the electrical
energy from the Generator into mechanical vibration. The Front Driver transmits and amplifies the
vibration out of the Handpiece casing. A Probe is attached to the Front Driver by an integral
mounting stud. This Probe amplifies the motion and provides the debriding surface of the device.
As applications require, various Probe configurations will be used to extend the working length,
provide increased amplification of vibration, or for fast removal of tissue. The Handpiece
incorporates a provision for aspiration fluid connection. The Handpiece is attached to the Generator
by a 12-foot long autoclavable Handpiece Umbilical Cable. Two sizes of Handpieces are available,
the Standard Handpiece and the FineLine
™
Handpiece.

40-OM-0002 Page 14 of 43 Rev B
2.3.3. Probes
Broad range of sizes and lengths for micro and macro tissue removal.
Probes can be used on two Handpieces, standard and micro..
2.3.4. Aspiration Unit (Optional)
An optional basic Aspiration unit or a complete Aspiration and Infiltration Platform may also be
ordered for use in the surgical site. An optional Aspiration Unit (Model: PT-ASP-III-110 or 220)
includes a vacuum pump, vacuum gauge, and vacuum control to adjust the level of vacuum
available at the Probe. A reservoir is attached to the pump via a suction line to collect waste liquid.
A filter assembly is provided to protect the pumps and the environment from aerosolized aspirant
droplets. The Aspiration units are connected to the Handpiece with sterile disposable flexible
tubing that is replaced before each procedure.
A separate ON/OFF switch is provided on the Aspiration units to allow independent use and testing
of the aspirating feature of the device.
The liquid reservoirs recommended by Byron Medical, Inc., prevents liquid from being transported
to the pump via the suction line.
