A lead includes a lead body with a stylet receiving lumen, a distal tip, and a distal portion proximal of the distal tip that is biased to assume a non-linear configuration. Insertion of a stylet into the lumen causes the distal portion to transition from the non-linear configuration to a generally linear configuration. The lead also includes a first arm member having a distal end and a proximal end coupled to the lead body proximal of the distal tip; and a nosepiece, at least a portion of which is biodegradable. The nosepiece is configured to receive the distal tip of the lead body and the distal end of the first arm member such that the lead body, first arm member and nosepiece form a closed arrangement prior to biodegradation of the nosepiece and an open arrangement after biodegradation of the nosepiece.
