Making T-Implants

Allow 2-3 days drying time before the use of implants to ensure adequate drying of the silicone cap.

To be done 1 day prior to filling with testosterone powder.

  1. Cut desired lengths (eg. 3mm, 5mm or 10mm) of silastic tubing leaving extra length for the silicone seal. For example for a 5mm long pump, leave extra 3mm on each side, so cut tubing into 11mm lengths.
  2. Cap one end of the tube with roughly 3mm of silicone. The easiest way to do this is to fill a 3ml syringe with silicone and using an 18G needle to direct the silicone flow into the tube. Make sure no air-bubbles are present in the silicone.
  3. Leave implants to dry overnight in a fume cupboard.

Filling T-Implants

Continue remaining steps in the fume cupboard.

You will need:

  • Ruler
  • Forceps
  • Small Funnel
  • Glass Pipette
  • Vortex

 

  1. Once dry, fill the tube with the desired amount of testosterone powder by using a glass pipette with the tip cut off. Push the end of the glass pipette into the open end of the implant up to the length required (measured using a ruler).
  2. Once in position, fill the pipette with powder (using a funnel). Give the implant end a gentle pulsatile vortex to shake the powder into the silastic tube. Make sure the powder is packed in tightly; the powder will look smooth in appearance.
  3. Check the length of the compacted powder.
  4. When satisfied with length and compactness, remove the pipette from the tube, making sure not to loosen the powder within.
  5. Seal the opened end with silicone.

Allow at least 3 days for the silicone to dry completely before implantation.
