Abstract
The present invention relates to steerable access sheath assembly (12). Moreover, the present invention relates to a steerable short sheath access device (10) for use in epicardial procedures. Embodiments of the present invention including shorter steerable access sheaths or introducers (10, 12) may provide epicardial access for various ablation tools and devices for the performance of various ablation procedures or procedures involving alternate energy sources. The steerable access device (10) provides an elongated member (20) having a proximal section (26) and a distal section (28), wherein the deflection of the distal section (28) provides a primary curve including an inner radius (r1) that result in a secondary curve of proximal section (26) having an inner radius (r2, r3), wherein the inner radius of curvature (r1) of the primary curve is less than the inside radius of curvature (r2, r3) of the secondary curve.
