Abstract:
1. A steerable sheath access device, comprising: an elongated member having a proximal end, a distal end, and a lumen extending through the elongated member from the proximal end to the distal end; the elongated member having a proximal section made of a first material and a distal section made of a second material, the proximal section extending from the proximal end to an intersection of the proximal section and the distal section, and the distal section extending from the intersection of the proximal section and the distal section to the distal end, a first pull wire connected to the elongated member, the first pull wire extending along the length of the elongated member from a handle assembly to at least the intersection of the proximal section and the distal section, a second pull wire connected to the elongated member, the second pull wire extending along the length of the elongated member from a handle assembly to at least a distal end of the distal section; a first anchor ring that is at least in part provided within the lumen of the elongated member, and the first anchor ring is connected to the first pull wire; and a second anchor ring is provided at least in part within the lumen of the elongated member, and the second anchor ring is connected to the second pull wire; wherein the first material of the proximal section is more rigid than the second material of the distal section; wherein the elongated member is configured such that deflection of the distal section defines a primary curve including a first inner radius of curvature, wherein the elongated member is configured such that deflection of the proximal section defines a secondary curve including a second inner radius of curvature, and wherein the first inner radius of curvature of the primary curve is less than the second inner radius of curvature of the secondary curve.
