Abstract
Apparatus and associated methods relate to a guidewire slack take-up module (STUM) that engages a guidewire, by a retractor module (RM), to displace the guidewire in a proximal direction (D) in response to a tensioning command signal (TCS) and maintains a predetermined biasing force (PBF) in Dwhen the RM is not engaged. In an illustrative example, the STUM may include a connection module (CM) disposed at a proximal end of a control member (CM). The CM may have its distal end fixedly attached to a distal end of a flexible shaft. The RM may, in response to the TCS, engage the CM to displace the proximal end of the CM in D. A biasing member may apply the PBF to the CM in Dwhen the RM is not engaging the CM. Various embodiments may advantageously reduce or eliminate slack in a guidewire of a steerable catheter.
