摘要

Steerable medical devices and methods of use. In some embodiments, the steerable medical devices can be steered bi-directionally. In some embodiments the steerable medical devices include a first flexible tubular member and a second flexible tubular member secured together at a location distal to a steerable portion of the steerable medical device.

主权项

1. A steerable medical device, comprising:
an inner flexible tubular member with an inner spine; an outer flexible tubular member axially fixed to the inner flexible tubular member at a fixation location distal to a steerable portion, the outer tubular member having an outer spine that is offset from the inner spine, and a linear reinforcing member extending within the outer spine; and an external controller operatively interfacing with the inner and outer flexible tubular members to put one of the inner and outer tubular members in tension and the other in compression, to steer the steerable portion.
