Abstract

Official abstract text for this publication.

A lead fixation device for securing a first portion of a lead relative to a hole formed through a skull includes a skull attachment member having an upper surface and a lower surface and a bore extending through and between the upper surface and the lower surface. The lead fixation device also includes a lead compression mechanism integral with the skull attachment member and aligned with the bore of the skull attachment member. The lead compression mechanism defines a passageway through the lead fixation device, which passageway is characterized by a diameter that is defined by the lead compression mechanism. The lead compression mechanism is configured to transition the diameter from a first size to a second size greater than the first size upon insertion of an implant tool through the passageway, and from the second size to the first size upon removal of the implant tool from the passageway.

First claim

Opening claim text (preview).

What is claimed is: 1. A lead fixation device for securing a portion of a lead relative to a surface of a skull, the lead fixation device comprising: a skull attachment member having an upper surface and a lower surface; and a compression mechanism integral with the skull attachment member and forming a passageway relative to the skull attachment member, which passageway is characterized by a slot that extends along a length of the passageway, wherein the compression mechanism is configured to: transition a width of the slot from an initial size to an expanded size that is greater than the initial size upon a receipt of appropriately directed first forces in a region of the compression mechanism that forms the passageway, and transition the width of the slot from the initial size to a collapsed size upon a receipt of appropriately directed second forces in a region of the compression mechanism that forms the passageway. 2. The lead fixation device of claim 1 , wherein the compression mechanism is formed of a flexible material. 3. The lead fixation device of claim 1 , wherein the portion of the lead has a diameter, and the initial size is less than the diameter and the expanded size is greater than the diameter. 4. The lead fixation device of claim 1 , wherein the skull attachment member is formed of a material more rigid than the compression mechanism. 5. The lead fixation device of claim 1 , wherein the slot faces in the direction of the lower surface of the skull attachment member. 6. A lead fixation device for securing a portion of a lead relative to a surface of a skull, the lead fixation device comprising: a skull attachment member having an upper surface and a lower surface; and a compression mechanism integral with the skull attachment member and forming a passageway relative to the skull attachment member, which passageway is characterized by a slot that extends along a length of the passageway and faces in the direction of the lower surface of the skull attachment member, wherein the compression mechanism comprises at least one wing extending to a side of the passageway and along the lower surface of the skull attachment member and is configured to: transition a width of the slot from an initial size to an expanded size that is greater than the initial size upon a receipt of appropriately directed first forces in a region of the compression mechanism that forms the passageway, and transition the width of the slot from the initial size to a collapsed size upon a receipt of appropriately directed second forces in a region of the compression mechanism that forms the passageway. 7. The lead fixation device of claim 1 , wherein the slot faces in the direction of the upper surface of the skull attachment member. 8. The lead fixation device of claim 1 , wherein the passageway extends along the upper surface of the skull attachment member. 9. The lead fixation device of claim 1 , wherein the passageway extends along the lower surface of the skull attachment member.
