Chapter 1
Introduction
This chapter provides an overview of the features and functions of the Valleylab LS10, LS Series Single Channel Vessel Sealing Generator.
The Generator is designed to provide a vessel sealing application. It features a simple interface and automatically detects LigaSure™ instruments and BiZact™ instruments and configures the generator accordingly. Safety and diagnostic functionality include automatic fail-safe functions.
The generator is a bipolar electrosurgical generator with no neutral electrode needed and works with LigaSure/BiZact instruments as a system. Covidien offers a selection of LigaSure//BiZact instruments that are fully compatible with this generator. The generator supports only compatible Covidien LigaSure and BiZact instruments.
Precaution
Read all warnings, precautions, and instructions provided with this system before use.
Read the instructions, warnings, and precautions provided with LigaSure and BiZact instruments before use. Specific instructions for LigaSure instruments are not included in this manual.
Indications for Use
Indications for Use
The Valleylab LS10 is an electrosurgical generator containing vessel sealing technology. The vessel sealing function is indicated for use in sealing (fusing) vessels up to, and including, 7 mm in diameter, tissue bundles, and lymphatics during general surgery including, but not limited to, surgical specialties such as urologic, vascular, thoracic, gynecologic, plastic and reconstructive, and colorectal.
Refer to each instrument’s instructions for use (IFU) for additional indications, warnings, and specific contraindications.
The tissue fusion function has not been shown to be effective for tubal sterilization or tubal coagulation for sterilization procedures. Do not use this function for these procedures.

LigaSure Mode
The LigaSure vessel sealing mode can be used on arteries, veins, pulmonary vasculature, and lymphatics up to and including 7 mm in diameter and tissue bundles. This system provides precise energy delivery and electrode pressure to vessels for a controlled time period to achieve a complete and permanent fusion of the vessel lumen. The system is designed to produce minimal sticking, charring, and thermal spread to adjacent tissue.
Warning
Do not attempt to fuse lung tissue with LigaSure mode or instruments without first consulting the respective instrument instructions for use for indicating such use.
LigaSure Instruments
The LigaSure instruments that complete the Valleylab vessel sealing system include reusable and single-use instruments for open and minimally-invasive procedures. Each reusable instrument requires a corresponding single-use electrode. The LigaSure function is only available when using Covidien LigaSure instruments.

Chapter 2
Patient and Operating Room Safety
The safe and effective use of vessel sealing technology in surgical procedures depends to a large degree upon factors solely under the control of the operator. There is no substitute for a properly trained and vigilant surgical team. It is important that the operating instructions supplied with this or any electrosurgical equipment be read, understood, and followed.
Before starting any surgical procedure, the surgeon should be trained in the particular technique and surgical procedure to be performed, should be familiar with the medical literature related to the procedure and potential complications, and should be familiar with the risks compared to the benefits of utilizing vessel sealing technology in the procedure.
General
General
Setting Up the System
Warning
Electric Shock Hazard Connect the system power cord to a properly grounded power receptacle.
Do not use power plug adapters.
Do not connect wet instruments to the generator. Ensure that all instruments and adapters are correctly connected and that no metal is exposed at any connection points.
Fire Hazard Do not use extension cords.
Patient Safety Use the generator only if the power-up self-test has been completed as described
in this manual, otherwise inaccurate power outputs may result.
Hazardous Electrical Output This equipment is for use only by trained, licensed physicians.
Do not use electrosurgical equipment unless properly trained to use it in the specific procedure being undertaken. Use of this equipment without such training can result in serious, unintended patient injury, including bowel perforation and unintended, irreversible tissue necrosis.
Do not wrap the instrument cords around metal objects. This may induce currents that could lead to shocks, fires, or injury to the patient or surgical team.
Contact between the active electrode and any metal will greatly increase current flow and can result in unintended surgical effect.
While using vessel sealing technology in surgical procedures, the patient should not be allowed to come into direct contact with grounded metal objects (e.g., surgical-table frame, instrument table, etc.). If this is not possible during certain procedures (e.g., those in which noninsulated head frames are used), use extreme caution to maximize patient safety:
• Place dry gauze between the patient and the grounded object if possible.
• Continually monitor the contact point(s).
• Do not use metal needle monitoring electrodes.
• In all cases, monitoring systems incorporating high frequency current limiting devices are recommended.
A failure of the LS10 could result in an unintended increase of output power.
Precaution
Read all warnings, precautions, and instructions provided with this generator before using.
Read the instructions, warnings, and precautions provided with LigaSure instruments before using. Specific instructions for LigaSure instruments are not included in this manual.
Precaution
Examine all instruments and connections to the system before using. Ensure that the LigaSure instruments function as intended. Improper connection may result in arcs, sparks, instrument malfunction, or unintended surgical effects.
Do not turn the activation tone down to an inaudible level. The activation tone alerts the surgical team when the generator is delivering RF energy.
A non-functioning generator may cause interruption of surgery. A backup system should be available for use.
Inadvertent activation may occur while installing or removing jaw electrode plates on compatible LigaSure Instruments. Ensure that the instrument cord is not connected to the generator or that the system is OFF.
General
Patient and Operating Room
When using a smoke evacuator in conjunction with the generator, set the system volume control at a level that ensures that the activation tones can be heard.
Connect only Covidien approved LS0300 footswitch (purple). Using footswitches from other manufacturers may cause equipment malfunction.
Use caution if stacking equipment on top of the generator or placing the generator on top of electrical equipment. This is an unstable configuration and does not allow for adequate cooling.
