"flip type: due to pulse generator rotation in a transverse direction; all leads retract and wrap around the generator"
"reel type: due to pulse generator rotation in a clockwise/anticlockwise direction; all leads retract and wrap around the generator in a coil-like fashion"
"ratchet type: (most common subtype) due to stepwise one-way retraction of the lead towards the pulse generator; one or more leads retract and accumulate within the subcutaneous pocket"
"twiddler type: due to pulse generator rotation in a craniocaudal direction; all leads retract and are twisted around each other"
"fixation release type: simple dislodgement of one or more leads with no change in the position of the pulse generator; there is a lack of lead slack"
