Abstract

A steerable sheath includes an inner liner extending from a proximal end to a distal end of the steerable sheath. The inner liner includes a non-deflectable portion and a deflectable portion. The steerable sheath includes a first pull wire positioned along a first helical path around the circumference of the inner liner from a proximal end to a distal end of the non-deflectable portion of the inner liner and along a first straight path from a proximal end of the deflectable portion to a distal end of the deflectable portion. The steerable sheath includes a second pull wire positioned along a second helical path around the circumference of the inner liner from the proximal end to the distal end of the non-deflectable portion and along a second straight path from the proximal end of the deflectable portion to the distal end of the deflectable portion.
