PAIRED MEDICAL LEAD BODIES WITH BRAIDED CONDUCTIVE SHIELDS HAVING DIFFERENT PHYSICAL PARAMETER VALUES

摘要

Medical lead bodies that are paired each include a braided conductive shield. The braided conductive shield of one lead body has a value for a physical parameter that differs from a value for the physical parameter of the second lead body. The difference in values of the physical parameter for the paired lead bodies results in a reduction in heating from exposure of the lead bodies to radiofrequency energy at electrodes associated with the lead bodies. The lead bodies may be paired by being implanted adjacently to one another. The lead bodies may be further paired by being coupled to a same distal body, such as a paddle containing the electrodes.

主权项

1. A medical lead, comprising:
a first lead body housing a first filar connected to a first proximal contact on the first lead body, the first lead body having a first braided conductive shield with a first value of a weave angle; a second lead body housing a second filar connected to a second proximal contact on the second lead body, the second lead body having a second braided conductive shield with a second value of the weave angle that is different than the first value; and a body housing a plurality of electrodes, the body being coupled to the distal end of the first and second lead bodies with a first electrode of the plurality connected to the first filar and a second electrode of the plurality connected to the second filar.
