Introducing the brand new Cardiology IV stethoscope from 3M Littmann. The Cardiology IV stethoscope encompasses a redesign from the ground up featuring a brand new stainless steel chestpiece, brand new fully optimised paediatric and adult diaphragms unique to the Cardiology IV, the very latest generation long life tubing, a highly tuned bell side for instant low frequencies, and class leading 7 year warranty. This is the upgrade you have been waiting for...

As with the Cardiology III, full acoustic range adult and pediatric auscultation is available through its newly designed dual head chestpiece. Simply rotate the central spline to alternate between the two sides for superior adult and pediatric auscultation. The brand new single piece diaphragms (unique to the Cardiology IV), have further optimised acoustic sensitivity, making all sounds clearer and easier to hear! The new long life binaural (two tubes in one) are the very latest specification, and latest materials, helping raise the warranty length to an industry leading 7 years! The selector spline is now recessed to allow a perfect flush fit with the binaural tube, now featuring a visual indicator for easy identification of the operational diaphragm.

Did we mention it can be engraved too?

Satin Finish Tubing

Littmann stethoscope’s Satin Finish Tubing formula means that the same performance you’ve come to expect from the 3M™ Littmann® Cardiology IV™ Stethoscope is now available with a more comfortable, flexible feel that is not likely to stick to hair or clothing.

Littmann stethoscopes’ satin finish also offers a more flexible feel for easier folding and stowing of your stethoscope, so you can keep it with you between patients, and its specially-formulated coating is easy to clean, with debris- and scuff-resistance to help preserve the look and life of your stethoscope.

When compared to uncoated tubing, Satin Finish Tubing is:

• Softer with a silkier feel,
• More stain-resistant,
• Easier to clean, and
• Featuring a pliability that makes it easier to put into a lab coat.
• More than twice as loud* as the next leading stethoscope
• Allows you to more reliably and consistently hear heart sounds at lower frequencies (below 120Hz*) like Korotkoff sounds, Mitral Stenosis and S3 and S4 Gallops when compared to other leading stethoscopes.
• Weighs less** than other stethoscopes
