Device for manipulating a stylet unit

A device for manipulating a stylet unit having a stylet sleeve and a stylet guide wire disposed within the stylet sleeve, for positioning an electrode cable in a body cavity, said electrode cable having a central elongated lumen into which the stylet unit is to be inserted, said device comprising:

• a handle having a first handle member and a second handle member attached to each another for relative movements thereof, said handle members respectively being connected to respective proximal ends of said stylet sleeve and said stylet guide wire;
• a fixation arrangement attached to a distal portion of one of said handle members adapted for fixing a proximal contact element of the said electrode cable to said one of the said handle members, said fixation arrangement being displaceably mounted relative to said one of said handle members so as to be adjustable to accommodate variations in length of said central elongated lumen of said electrode cable;
• and
• said fixation arrangement comprising a slide member slidably mounted in a single bracket member having a proximal base portion rotatably attached to said one of said handle members, and a distal shaft portion having a guide track for said slide member, said slide member carrying a locking mechanism adapted for securing said proximal contact element of said electrode cable to said slide member.
