1. A method of securing a temporary neurostimulation lead relative to an entry point on a patient, the method comprising:
- implanting the temporary neurostimulation lead within the patient such that the temporary neurostimulation lead extends through the entry point and is disposed proximate a desired nerve within the patient;
advancing a fixation device over the temporary neurostimulation lead to a position proximate the entry point, the fixation device including an attachment portion configured to be releasably fixated to the patient and a lead fixation portion configured to secure the temporary neurostimulation lead, the lead fixation portion comprising one or more raised portions that are configured to frictionally engage a spiral-cut strain relief element having a groove around a circumference and continuous along a length of the strain-relief element;
adhesively fixating the attachment portion of the fixation device to the patient; and
fixating the temporary neurostimulation lead to the lead fixation portion of the fixation device by wrapping the temporary neurostimulation lead within the groove of the spiral-cut strain relief snapping the spiral-cut strain relief into the one or more raised portions.

Abstract
A temporary neurostimulation lead may be secured relative to patient using a fixation device. The fixation device may include an attachment portion that is configured to be releasably fixated to the patient and a lead fixation portion that is configured to secure the temporary neurostimulation lead. The fixation device can be adhesively fixated to the patient via the attachment portion and the temporary neurostimulation lead can be fixated to the lead fixation portion of the fixation device.

8. A fixation device configured to releasably secure a temporary neurostimulation lead relative to an entry point on a patient, the device comprising:
-
a polymeric device body having a lower surface and a upper surface; a dermatologically safe adhesive disposed on the lower surface for releasably securing the fixation device to the patient proximate the entry point; a strain relief member arranged on the upper surface of the polymeric device body and having a groove configured to engage the temporary neurostimulation lead within the groove, the groove being spirally arranged around a circumference and continuous along a length of the strain relief member; and a lead fixation structure formed on the upper surface having a curved channel configured to frictionally engage with the strain relief member to releasably secure the temporary neurostimulation lead. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A fixation device configured to releasably secure a temporary neurostimulation lead relative to an entry point on a patient, the device comprising:
-
a polymeric device body having a lower surface and an upper surface; a dermatologically safe adhesive disposed on the lower surface for releasably securing the fixation device to the patient proximate the entry point; a spiral-cut strain relief element including an elongate body and a spiral groove formed within the elongate body, the spiral groove arranged around a circumference and continuous along a length of the strain-relief element and configured to accommodate the temporary neurostimulation lead therein; and a pair of raised portions molded into the upper surface, the pair of raised portions being configured to frictionally engage the spiral-cut strain relief element. - View Dependent Claims (17, 18, 19)
