1. A lead anchor to secure a stimulation lead with an internal lead lumen, the lead anchor comprising:
a first clamping element, wherein a first clamp surface is on the first clamping element;
a second clamping element, wherein a second clamp surface is on the second clamping element and the second clamp surface is opposed to the first clamp surface;
an adjustable fastener configured to selectively move the first clamping element relative to the second clamping element to draw the first clamp surface towards the second clamp surface to secure the stimulation lead located between the first clamp surface and the second clamp surface; and
an exterior sleeve that captures the first clamping element, the second clamping element and the adjustable fastener;
wherein the exterior sleeve comprises a pocket in which the first clamping element, the second clamping element and the adjustable fastener are located;
wherein the first clamping element is slidingly engaged with the second clamping element to:
(i) enable relative movement of the first clamp surface towards the second clamp surface along a clamping axis; and
(ii) restrict relative movement of the first clamp surface and the second clamp surface around the clamping axis;
wherein the first clamp surface and the second clamp surface are profiled to apply clamping force to secure the stimulation lead while maintaining an open internal lead lumen;
wherein at least one of the first clamping element and the second clamping element includes an arcuate concave surface; and
wherein the first clamping element, the second clamping element and the adjustable fastener are insertable into the pocket, wherein the pocket is sealable by a door to capture the first clamping element, the second clamping element, and the adjustable fastener.
