CARDIAC LEAD WELDING

摘要

An implantable lead may have a distal assembly including a coupler, a terminal pin and a conductive member rotatably secured to both the coupler and the terminal pin. The conductive member may be a fine-wire, multiple-filar coil. The conductive member may be welded to the coupler and/or the terminal pin by welding through banded portions formed within the distal and proximal ends, respectively, of the conductive member.

主权项

1. A method of assembling an extendable/retractable active fixation lead having a coupler and a conductive member secured to the coupler, the conductive member having a distal region and a proximal region, the coupler including a proximal portion configured to accommodate the distal region of the conductive member, the method comprising:
subjecting the distal region of the conductive member to heat and pressure to form a banded portion; disposing the banded portion of the conductive member about the proximal portion of the coupler; and welding the banded portion of the conductive member to the coupler.
