Study Type : Observational
Estimated Enrollment : 230 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: RELEASE: Transvenous Lead Removal Using the Cook Evolution® Lead Extraction System Post-Market Clinical Study.
Actual Study Start Date : October 18, 2018
Estimated Primary Completion Date : April 2020
Estimated Study Completion Date : May 2020

Group/Cohort Intervention/treatment
Cook lead extraction devices
The Cook lead extraction devices are indicated for use in patients requiring percutaneous removal of CIED leads, indwelling catheters and foreign objects.
Device: Cook lead extraction devices
The Cook lead extraction devices are mechanical devices that encompass a full variety of devices required for percutaneous removal of CIED leads, indwelling catheters and foreign objects.

Primary Outcome Measures :
  1. Rate of complete procedural success [ Time Frame: Immediately following lead extraction ]
    Complete procedural success is the removal of the targeted lead and all lead material from the vascular space, with the absence of permanently disabling complications or procedure-related death.

  2. Rate of clinical procedural success [ Time Frame: Immediately following lead extraction ]
    Clinical procedural success is the removal of all targeted leads and all lead material from the vascular space, or retention of a small portion of the lead (fragment that is 4 cm or smaller) that does not negatively impact the outcome goals of the procedure.
