Introduction 1-1
CHAPTER 1
Introduction
The TEExp transducer is a transesophageal echocardiographic transducer designed to
operate with the SonoSite X-Porte ultrasound system built by FUJIFILM SonoSite, Inc.
Transesophageal procedures carry a variety of inherent risks to the patient. The information
and instructions in this user guide are intended to help you minimize those risks. In addition,
the TEExp transducer is a highly complex and delicate precision instrument. Misuse or poor
handling may severely shorten the service life.
About the user guide
This user guide provides information on the TEExp transducer. It is designed for a reader
familiar with ultrasound and proper endoscopic techniques; it does not provide training in
sonography, cardiology, echocardiography, or clinical practices. For information about the
ultrasound system, see its user guide and other appropriate literature.
To aid in safeguarding the patient and ensuring reliable transducer operation, SonoSite
recommends having this user guide available for reference during all stages of TEExp
transducer handling, and refer to guidelines from the American Society of
Echocardiography for Point of Care TEE (ASE) and the Academy of Emergency Physicians
(ACEP).
WARNING To help avoid conditions that may cause harm to the patient or
damage to the transducer, it is important that personnel using
or handling this transducer read and understand the
instructions, warnings, cautions, and training material contained
in this user guide. If you have questions about any of the
information contained in this user guide, contact FUJIFILM
SonoSite or your local representative.

Changes in this version
Conventions
The document follows these conventions:
A WARNING describes precautions necessary to prevent injury or loss of life.
A Caution describes precautions necessary to protect the products.
A Note provides supplemental information.
Numbered and lettered steps must be performed in a specific order.
Bulleted lists present information in list format but do not imply a sequence.
For labeling symbols used, see the ultrasound system user guide.
Warranty statement
The TEExp transducer is warranted for material and workmanship only, for a period of 12 months from date
of shipment from FUJIFILM SonoSite.
The warranty does not cover damage caused by patient bite, misuse by the end user, disinfecting incorrectly
or with chemicals not approved by FUJIFILM SonoSite, or circumstances beyond what is considered normal
for the product’s intended application.
Technical Support
To order sheaths, bite guards, tip covers, and other supplies, see www.civco.com.
Change Description
Added references Added references to ACEP, ASE, and SCA guidelines.
Clarified terminology Changed the term “deflection” to “flexion,” which describes
the behavior of the probe more appropriately.
Bite guard/bite block Added “bite block” as an additional term to prevent
confusion. Emphasized bite guard use.
Leakage tester update Updated the leakage test procedure to support the new
leakage tester. Integrated the leakage test into the cleaning
and disinfection process.

Getting started
About the TEExp transducer
The TEExp transducer is an electronically steered phased array ultrasound transducer
assembly, mounted in a sealed tip at the end of a conventional endoscope.
The TEExp transducer is used to generate a set of ultrasound images or slices within a cone
from the same position in the esophagus. The rotation of the scan plane is driven by a
motor in the control handle.
WARNINGS FUJIFILM SonoSite does not recommend the use of
high-frequency electromedical devices in proximity to its
systems. FUJIFILM SonoSite equipment has not been validated
for use with high-frequency electrosurgical devices or
procedures. Use of high-frequency electrosurgical devices in
proximity to its systems may lead to abnormal system behavior
or shutdown of the system.
To avoid the risk of a burn hazard, do not use the transducer
with high-frequency surgical equipment. Such a hazard may
occur in the event of a defect in the high-frequency surgical
neutral electrode connection.
To avoid injury to a patient, the TEExp transducer is intended
for use by a medical professional who has received appropriate
training in endoscopic techniques as dictated by current
relevant medical practices, as well as in proper operation of the
ultrasound system and transducer. Adhere to the standards and
protocols from the American Society of Echocardiography for Point of
Care TEE and the American College of Emergency Physicians.
Caution To avoid inadvertent damage to the transducer, read this user
guide before handling and cleaning the TEExp transducer.

2-2 Getting started
Intended uses
The TEExp transducer is an endoscopic transducer designed for 2D, M Mode, color Doppler (Color), pulsed
wave (PW) Doppler, and continuous wave (CW) Doppler imaging by applying ultrasound energy through
the esophagus or stomach of the patient into the heart. The TEExp transducer is intended to be used on
adults only. Backscattered ultrasound energy from the patient’s heart forms images of the heart to detect
abnormalities in structure or motion, to evaluate the velocity of blood flowing within the heart, and to obtain
a color depiction of the velocities of blood flowing in the heart.
Contraindications
Contraindications for using a transesophageal transducer include, but are not limited to, the following:
Fetal imaging
Pediatric imaging
Imaging when the patient exhibits the following or similar conditions:
Esophageal stricture, spasms, lacerations, and trouble swallowing (dysphagia)
Esophageal diverticula, esophageal varices (swollen veins)
Gastrointestinal bleeding
Peptic ulcers, hiatal hernia, esophageal webs and rings
Recent radiation treatment to the esophagus
Inability to swallow or accommodate the transducer
History of gastroesophageal diseases
Unpacking
Proper care and maintenance are essential. Follow the unpacking procedures. Contact FUJIFILM SonoSite or
your local representative immediately to report any damage or discrepancies.
WARNING The physician must consider all possible factors before starting the examination.
WARNING To avoid injury to patient/operator, carefully inspect all equipment after receipt
and prior to each use.
