| 摘要 |
A catheter actuator (10) which includes at least two carriers (12,14) displaceably arranged relative to each other, a first catheter sheath component (16) of a catheter sheath assembly (17) being connectable to the first carrier (12) and a second catheter sheath component (18) of the catheter sheath assembly (17) being connectable to the second carrier (14). A control mechanism (22) is carried, in use, by a catheter handle (24) and associated with the carriers (12, 14) to effect relative displacement between the carriers to cause displacement of a distal end of at least the first catheter sheath component between a non-deployed position and a deployed position. The control mechanism includes a movement control member (46) mounted fast with the catheter handle, the control mechanism being operable to control displacement of a combination of the first carrier and the second carrier relative to a further component (26) of the catheter, at least a part of which is fast with a body of the catheter handle.
