Abstract
Systems and methods which provide retractable anchor configurations for medical device leads are described. A retractable anchor may implement a retractable distention composed of a resilient material. The retractable distention may be distended when in a neutral state and may be contracted when in a biased state. A biasing bulkhead may be configured to receive a bias force sufficient to retract the retractable distention. A stylet may be inserted into an axial lumen of a medical device lead having retractable tip anchor structure and may engage the biasing bulkhead to apply a bias force. A stylet knob may be configured to interface with the stylet and provide bias force to be transferred to the biasing bulkhead of the retractable tip anchor structure. Locking the stylet knob on the medical device lead may maintain the bias force applied to the biasing bulkhead until the stylet knob is unlocked.
