摘要:
A spool and gear mechanism for tensioning and manipulating the steering/deflection control wires of a steerable catheter device provides for a desired level of tension that will allow operation of the device without too little or too much tension in those wires. In a wire-tensioning mechanism for a steerable catheter, the mechanism includes at least a first and second steering/deflection control wire each attached to the spool by winding around its own detent-engaged rotatable gear in the spool and extending out through a radial wall of the spool to engage into a steerable catheter body. In a multi-spool system, the wire-tensioning/winding gears of each spool preferably are accessible for adjustment via apertures of an adjacent spool.
