A steerable medical device comprises an elongated tubular body and first and second stiffening members, preferably in the form of compression coils or flat flexible wires. The stiffening members are arranged such that when a user engages a steering assembly, incorporated into the device, a distal end of the tubular body can be selectively bent in a first direction into a first configuration or in a second direction into a second configuration. The first and second configurations are functions of the lengths and locations of the first and second stiffening members. |
