The disclosure is directed to an implant tool (178) and cannula (154) used to facilitate the implantation of a medical device into a patient. The implant tool includes a housing (180) that is held by a user and a needle (190) attached to the housing. The cannula may be positioned over the needle and delivered to a target tissue within the patient. The cannula includes an electrode (160) at a distal portion to deliver test stimulation to confirm the location of the target site or placement of the implant tool relative to the target site before removing the Needle of the implant tool. In this manner, the cannula may be repositioned within the patient until the position of the implant tool and cannula relative to the target site is verified with the test stimulation.
