May 4, 2011 – A new version of the Liberator Locking Stylet with Beacon Tip Technology, a distinct radiopaque tip marker, was unveiled at Heart Rhythm 2011, the 32nd Annual Scientific Sessions of the Heart Rhythm Society, and is now available to physicians worldwide.
Locking stylets play a fundamental role in lead extraction procedures by providing internal support to the cardiac lead targeted for removal. The addition of the new radiopaque tip marker should allow for users to better track the progress of the Liberator locking stylet as it is being positioned prior to engagement within the lead. Enhanced visualization of the Liberator locking stylet should help physicians achieve their goal of locking a stylet as close to the lead’s distal tip as possible so that lead control is maintained during subsequent extraction sheath manipulations.
The Cook Medical Liberator Locking Stylet now includes a tip made of two highly radiopaque materials, which have been selected to make the stylet visible under fluoroscopy throughout the procedure. The Liberator’s popular locking system and its twisted wire handle will remain unchanged, and the new tip marker has been incorporated into the existing Liberator design in a manner that does not effect the look of the device or the mechanical functionality.
