| 摘要 |
A steerable tubular sheath is disclosed, such as for use in medical applications. The tubular sheath comprises an elongate flexible tubular body, having a laterally deflectable distal tip. Lateral deflection of the tip is accomplished by axial displacement of at least one pull wire extending through the housing. The housing comprises at least one central lumen extending axially therethrough, for receiving medical implements, fiber optics, suction or transmission of fluids such as for irrigation or drug delivery. In one particular embodiment, the steerable sheath is particularly adapted for irrigation and aspiration of the contents of the lens capsule of the eye.
