Feel control. See results.™
Experience controlled crossing, precise steering, and reliable performance in a bidirectional steerable sheath*
How it works
Animation showing the SureFlex Steerable Guiding Sheath
Controlled crossing*†
The Steerable Sheath offers a smooth sheath-dilator transition and lower crossing force for greater control*
Precise steering*‡
Feel your curve, know your position. Achieve maximum precision and control* with TruGlide™ handling and intuitive tactile feedback
Reliable performance*§
Durable design is engineered to provide consistent sheath tip contact force and superior retention of curve range-of-motion*

† Assessed by laser micrometery measurements along the length of the sheath-dilator transition (p<0.001, 5 SureFlex™ compared to 5 competitor sheaths) and by force gauge measurements during simulated transseptal crossing (p<0.001, 10 SureFlex™ compared to 8 competitor sheaths).
‡ Assessed by handle rotation to a full 360° to test axial torque transfer and the maximum rotational capabilities of each sheath (5 SureFlex™ sheaths compared to 3 competitor sheaths).
§ Assessed by full bidirectional articulation to maximal extension up to 10 times to achieve mechanical fatigue
