OBJECTIVE
METHODS: In vitro MRI Evalua*on
To evaluate MRI-‐related issues for various fragments of an open-‐coil lead used for percutaneous peripheral nerve sPmulaPon (PNS).
BACKGROUND
treat shoulder pain.
12.7 cm
Open-‐coil MicroLead (SPR TherapeuPcs, Cleveland, OH) loaded inside 20-‐gauge introducer needle. Maximum possible length of lead fragment is 12.7-‐cm
Lead is insulated along its length except for the 15-‐mm distal Pp, the last 5-‐mm of which is bent to form an anchor designed to resist migraPon within the Pssue. Table 1. Different lengths of lead fragments that were much longer than most reported fragment lengths (approximately
