US 2019/0099596 A1 · LEAD FIXATION ACCESSORY, LEAD STABILIZATION TOOL, AND RELATED PROCEDURES

Abstract

A lead fixation accessory configured to be positioned over a skull hole and to transition between an opened state and a closed state during a lead implant procedure protects against lead migration by providing a mechanism for securing the lead in place at the skull hole while a stylet is removed from the lead. The lead fixation accessory remains in place after the implant procedure to provide chronic lead stability. A lead stabilization tool configured to access and grip a lead through a slotted cannula during the lead implant procedure also protects against lead migration by providing a mechanism for securing the lead in place at a point where the lead exits the skull hole while the slotted cannula is removed from the skull hole and peeled away from the lead.

Dependent claims

A lead fixation accessory for securing a lead to a skull, the lead fixation accessory comprising:

a first arm having opposed ends separated by a middle region;
a second arm having opposed ends separated by a middle region;
and
a coupling mechanism configured to couple respective first ends of the first arm and the second arm together so that the lead fixation accessory can transition between an open position during which the respective second ends of the first and second arms are displaced from each other, and a closed position during which the respective second ends of the first and second arms are engaged, and the respective middle regions of the first and second arms form at least one opening sized to secure the lead in place.
