IMPLANTABLE LEAD WITH COPLANAR CONTACT COUPLING

摘要

An implantable lead (30) for a medical device with a coplanar coupling (112) for connecting a conductor (34) to a contact reduces conductor bending moments to improve lead reliability. The conductor (34) is contained in the lead body (30) and extends from the lead proximal end to the distal end. The conductor (34) is also electrically insulated. The contact carried on the proximal end is electrically connected to the conductor. The coupling (112) has a conductor coupling (500) and a contact coupling (502). The conductor coupling (500) is placed over the conductor and attached to the conductor. The contact coupling (502) exits the lead body and has a weld (504) to connect the contact coupling (502) to the contact (36). The contact coupling (502) is configured to exit the conductor lumen and mate with the contact (36) while retaining the conductor coplanar to the lead body (30).
