摘要：
A medical apparatus includes an electrically conductive lead for a medical device, the lead having an internal bore terminating at a distal lead opening, and a lead delivery device for delivering the distal end of the lead to a blood vessel during implantation of the lead. The lead delivery device includes a removably anchorable guidewire, and a fixator attached to a distal portion of the guidewire for anchoring the guidewire. The fixator is movable between a compact configuration and an expanded configuration. The fixator is capable of passing through the distal lead opening of the lead in the compact configuration. The fixator is capable of exerting a holding force in the range of about 0.89 to 4.45 N in the lumen of the blood vessel in the expanded configuration.
