1. A method of inserting a payload into a destination vessel of a patient'"'"'s heart, comprising:
- providing an payload having a narrowed distal end;
providing a guide catheter for longitudinally guiding the payload;
providing a finishing wire, comprising;
a proximal shaft having a diameter; and
a ball-nosed distal end connected to a distal end of the proximal shaft, the ball nosed distal end having a diameter larger than the diameter of the proximal shaft, the ball-nosed distal end sized to interfere with the narrowed distal end of the implantable cardiac lead, and a combined length of the proximal shaft and ball-nosed distal end being greater than a length of the implantable cardiac lead;
inserting the guiding catheter into a chamber of the patient'"'"'s heart via an access vessel;
inserting the payload through the guide catheter into the destination vessel of the patient'"'"'s heart to seat the payload into a branch of the destination vessel;
inserting the finishing wire through the payload such that the ball-nosed distal end of the finishing wire contacts the narrowed distal end of the payload; and
fixing a proximal end of the finishing wire to secure the payload against dislodgment.

Abstract
A finishing wire with a ball nose tip is used to secure an implantable device such as a cardiac pacing lead during implantation procedures. The finishing wire includes a proximal shaft, and a ball-nosed distal end. The ball-nosed distal end of the finishing wire is sized to interface with an implantable device having a narrowed distal tip. The length of the finishing wire is greater than the length of the implantable device.
