NEUROSTIMULATION LEAD WITH STIFFENED PROXIMAL ARRAY

摘要

An implantable electrical lead is provided. The electrical lead comprises an electrically insulative, flexible, elongated lead body having a proximal end and a distal end, an electrical contact carried by the distal end of the lead body, an electrical terminal carried by the proximal end of the lead body, an electrical conductor axially extending within the lead body between the electrical contact and the electrical terminal, and a stiffening tube extending within the proximal end of the lead body from a point proximal to the terminal to a point distal to the terminal and proximal to the electrode. An implantable lead assembly kit comprises the implantable electrical lead, and a connector configured for firmly receiving the proximal end of the lead body. A method of implanting the electrical lead comprises introducing the electrical lead into a patient.
