The technology of the Gerresheimer Autoinjector:

Ideal for biopharmaceuticals and APIs

System overview

  • Easy handling for the patient (1 step to injection). Single use, single dose.
  • No pressure peak upon start of the injection.
  • Suitability for intramuscular or subcutaneous injection is plausible.
  • Ideal platform technology for a wide range of pharmaceutical formulations.
  • Injection volumes from 0.5 ml to 3.0 ml possible by using standard cartridges.

Key advantages

  • Superior delivery of viscous formulations:
    Formulations of up to 100 cP are plausible.
  • Pressurized system:
    Due to the constant pressure on the cartridge, there is no initial pressure peak and air bubbles are reduced or dissolved completely. Furthermore, the pressure eliminates the risk of unsterility of a moving plunger during transport.
  • Flexible needle system:
    Wide range of different needle sizes usable (diameters from 22G to 31G are plausible).
  • Cartridge system:
    No contact of the formulation with the needle during storage, thus no additional primary packaging components such as tungsten, steel or glue as usual for PFS. Cartridges with baked-on silicone usable.
  • Push-on-skin: 
    No separate activation button.

Status

  • Protection by own relevant IP claims: Worldwide patents are already granted.
  • Freedom to operate regarding third party rights.
  • Look and feel prototypes for demonstration purposes readily available.

Development Options

  • True platform: only few changes necessary to enable various formulations, volumes and viscosities (e.g. different spring forces or flexible needle lengths / diameter)
  • Customized features and design possible
