| 摘要 |
A steerable micro-device comprising a cylindrical elongated member having a distal end and a proximal end, the elongated member comprising a first lumen, a tensioning wire running in the first lumen, a distal end of the tensioning wire being attached at the distal end of the elongated member and a proximal end of the tensioning wire exiting the first lumen at the proximal end of the elongated member; the elongated member having a proximal portion extending from the proximal end toward the distal end of the elongated member and a distal portion extending from the distal end to the proximal portion of the elongated member, the proximal portion having a first durometer and the distal portion having a second durometer, lower than the first durometer; the first lumen being arranged such that the distal portion of the elongated body bends when pulling the proximal end of the tensioning wire. |
