Handling and Implantation
Information on the Steroid Collar
!
!
CAUTION
Premature elution of the steroid
Do not wipe the lead or immerse the lead in liquids any more than absolutely
necessary.
Intended medical use
The lead tip has a steroid collar in the form of a silicone rubber ring that contains
dexamethasone acetate.
The intended effect is the reduction of the inflammatory processes after
implantation and the inflammation-related post-operative threshold increase (lead
maturation behavior).
Long-term performance of
the steroid eluant
The greater the elapsed time since the implantation, the more the original amount
of steroid is eluted.
Over time, the maturation behavior of the lead begins to resemble that of the same
type of lead without steroid-eluting properties. This aspect must be considered if a
lead is to be repositioned.
