Steerable Sheath
A deflectable introducer sheath that allows precise catheter positioning and stability within cardiac chambers.
Full Definition
A steerable sheath is a specialized introducer sheath with deflectable capabilities that allows operators to precisely position and stabilize catheters within cardiac chambers during electrophysiology procedures. The sheath contains pull wires or mechanical systems that enable controlled angulation and direction of the sheath tip. Steerable sheaths are particularly valuable for complex procedures such as left atrial ablation, where they provide enhanced catheter stability, improved tissue contact, and better access to difficult anatomical locations such as the posterior wall and pulmonary vein antra.
Usage
Usage note: Brand names include Agilis and Destino sheaths. Essential for complex left-sided procedures.
