Keller Funnel ™

Every decision you make surrounding your breast augmentation is important — starting with should I use saline or silicone gel implants? Like you, millions of women around the world are considering the natural look and feel of silicone implants.

Designed by a Plastic Surgeon, The Keller Funnel™ improves the delivery of silicone gel implants during breast augmentation and reconstruction procedures. Today your Surgeon can give you the aesthetic advantages of silicone gel implants, combined with a gentler surgical approach.

Because every woman is different, and individual results may vary, speak to your Surgeon about the merits of the Keller Funnel™ and why using it in your procedure may provide the following benefits:

  • Shorter incision lengths
  • Improved comfort and faster healing
  • No touch technique
  • More choices for incision placement
  • Reduced force on the implant and incision
  • Reduced risk of contamination and infection

Capsular Contracture

Clinical papers suggest that while the causes of capsular contracture are multi-factorial, exposure to biofilms and bacterial contamination almost certainly have a relationship. Limiting handling of the implants and limiting skin contact prior to the insertion are also suggested.

Research shows that higher capsular contracture rates exist for procedures using periareolar incisions than for inframammary incisions, most likely due to an increase in contamination of the breast pocket with intraductal material colonized by bacteria.

Advocates of the “no-touch” technique claim eliminating implant skin contact will mitigate transfer of biofilms to the implant and should therefore reduce Bakers Grade III/IV capsular contracture, the most commonly occurring complication of breast augmentation.

FACT: The Keller Funnel™ allows a Surgeon to insert pre-filled breast implants into a surgical pocket using a “no-touch” technique that eliminates direct contact of the implants with the patient’s skin.

The FDA suggests that one of the mechanisms for rupture is damage during implantation.

The traditional insertion method whereby the implant is forced through an incision with the tip of the Surgeon’s finger causes significantly higher local stress than is caused with Keller Funnel usage. The Keller Funnel minimizes stress on the implant by dispersing a much smaller force over a much larger surface area.

By decreasing stress on the implant, long term intracapsular rupture rates may be reduced along with costly re-operations to replace failed implants. As an example, an independent engineering study showed that by using the Keller Funnel the measured force on a 300 cc smooth round implant inserted through a 3.5 cm incision was reduced from a mean of 8700 grams (19.2 lbs) to a mean of only 273 grams (0.60 lbs).


There is international consensus that complications and re-operations related to surgeries with breast implants or tissue expanders add significant long term cost to patients and health care providers.

Usage of the Keller Funnel™ positions Surgeons to be on the forefront of medical innovation and be proactive in working towards the goal of reducing complication rates for capsular contracture and intra-capsular implant ruptures.
