IMPLANTABLE MEDICAL LEAD AND METHOD OF MAKING SAME

摘要

An implantable medical lead may include a longitudinally extending body, an electrical conductor, an electrical component, and a weld. The longitudinally extending body includes a distal end and a proximal end. The electrical conductor extends through the body between the proximal end and the distal end. The electrical component is on the body and includes a sacrificial feature defined in a wall of the electrical component. The sacrificial feature includes a region that continues from the wall of the electrical component and a side that is isolated from the wall of the electrical component via a void defined in the wall of the electrical component. The weld is formed at least in part from at least a portion of the sacrificial feature. The weld operably couples the electrical component to the electrical conductor.

主权项

1. A method of assembling an implantable medical lead, the method comprising:
supporting an electrical component on a lead body, the electrical component comprising a sacrificial feature defined in a wall of the electrical component, the sacrificial feature comprising a region that continues from the wall of the electrical component and a side that is isolated from the wall of the electrical component via a void defined in the wall of the electrical component; and welding at least a portion of the sacrificial feature, a resulting weld operably coupling the electrical component to an electrical conductor extending through the lead body.
