The Keller funnel is a cone-shaped, sterile sleeve used to deliver a silicone implant into the pocket by squeezing it through the narrow end, rather than handling and pushing it in by hand.
Benefits
- Enables a no-touch insertion, reducing contact between the implant and skin.
- May allow a slightly smaller incision.
- Less direct handling and force on the implant.
Why it matters
Reducing skin contact during insertion is thought to lower bacterial contamination of the implant surface, which is relevant to capsular contracture and, in theory, rare surface-related conditions. The funnel is one of several no-touch tools used by many UK surgeons.
