3M™ Littmann® TeleSteth™ Server System

3M Littmann TeleSteth Online Auscultation System

With the TeleSteth™ System, you can easily incorporate both store-and-forward and real-time streaming of stethoscope sounds into your telemedicine program.

Features and Benefits:

Anytime, anywhere collaboration
Share heart, lung and airway sounds with colleagues located across the globe. Sounds are transmitted via a secure internet connection using either the 3M™ TeleSteth™ Cloud Server or your own private network using the TeleSteth™ Client Server.

Remote evaluation
The revolutionary technology behind the TeleSteth™ System allows you to evaluate patient sounds remotely, either in real-time during an exam, or at your convenience using store-and-forward mode (only available with TeleSteth™ Client Server).

Easy access
The TeleSteth™ System is designed to be accessed from a user’s PC via the internet. It’s fully integrated with the 3M™ Littmann® StethAssist® Heart and Lung Sounds Visualization Software that comes free with the Littmann Model 3200 Stethoscope.

Internet: TeleSteth™ Cloud Server

The Cloud Server allows you to conduct remote auscultations anywhere you have access to a high-speed internet connection.

The flexible, web-based architecture allows you to log onto a 3M-hosted server site where you can listen to a patient at a remote site using real-time live streaming.

How TeleSteth™ Cloud Server Works


  • Ideal for organizations with minimal IT Infrastructure investment
  • A Model 3200 Stethoscope, PC / laptop and high-speed internet connection are all that is required
  • Secure and robust
  • Includes technical support

System Requirements and Setup

  • The 3M Server creates real-time streams using TCP over SSL on ports 1100-1300
  • In order for the TeleSteth™ System to function properly, the client needs to be able to open an outgoing port in the designated range and pointed to the TeleSteth™ System server IP address
  • Requires purchase of software licenses, and annual maintenance fees after one year
  • Accounts can be provisioned within one-two business days of purchase

Private Network: TeleSteth™ Client Server Solution

The TeleSteth™ Client Server Solution is a server-based tele-auscultation system that runs on your own enterprise server. Through the easy-to-use software interface, you can quickly initiate live streaming auscultation sessions for real-time collaboration. Or you can use the store-and-forward mode to upload a recorded patient auscultation for later review by a consultant.

The server-based model offers enhanced flexibility with single sign-on user name and password that integrates with your current network system and operates within your own secure IT network.
