Mullin Sheath vs Transseptal Sheath: Understanding Their Role in Cardiac Access

Introduction

In interventional cardiology, accessing specific chambers of the heart requires precision and specialized devices. Mullin Sheath and Transseptal Sheath are commonly used tools that assist in guiding instruments during complex cardiac procedures.

Although both are used for intracardiac access, their application and procedural role differ. Understanding these differences helps clinicians choose the right sheath for safe and effective outcomes.

Product Overview

Mullin Sheath

The Mullin Sheath is primarily used as a guiding sheath during transseptal procedures. It provides stable support for needle advancement and helps in controlled access to the left atrium.

Transseptal Sheath

The Transseptal Sheath is specifically designed for crossing the interatrial septum. It facilitates smooth and safe passage of instruments into the left atrium during procedures such as electrophysiology studies and structural heart interventions.
