• Use bipolar electrocautery only.
• Have a plastic HiRes 90K Mock-up
• CI-4425 to help determine position
• of the implanted proposed incision line.
• Incision is posterior to the implant coil-
• antenna.
• Avoid placing incision over the implanted
• device.

6
Perform minimal shave posterior to device
magnet-coil.
7
Use plastic mock-up to help determine position of
implanted device.
8
Incision.
9
Use bipolar electrocautery only.
10
Raise the skin-muscle flap over the internal
magnet-coil.
11
Use freer elevator to access and lift original
magnet from the implant.
12
Things to consider

• When working with magnets, consider
• using non-magnetic tools and/or
• alternative magnetic-handling techniques.
• Have a non-metallic gimmick available
• to help position the replacement magnet.

13
Metallic surgical tools can be problematic when
manipulating the magnet.
14
Use sutures to retract the skin flap.
15
Use freer elevator to access and lift original
magnet from the implant.
16
Use non-metallic gimmick to seat magnet under
implant silicone lip.
17
Replacement magnet in place.

Things to consider

• Use a headpiece placed in a sterile
