Anchoring devices and methods for affixing an implanted lead of aneurostimulation system at a target location in a patient are provided herein.Such anchoringdevices includes a helical body having a plurality of tines extendinglaterally outward fromthe lead when deployed that engage tissue to inhibit axial movement of theimplanted lead.The plurality of tines are biased towards the laterally extended deployedconfiguration andfold inward towards the lead to a delivery configuration to facilitatedelivery of the leadthrough a sheath. The tines may be angled in a proximal direction or in bothproximal anddistal directions and may include various features to assist in visualizationand delivery of thelead. The anchor may be formed according to various methods, including lasercutting of atubular section along with heat or reflow to set the material with the anchorin the deployedconfiguration and injection molding.
