Patent ID: 8574200

Claim:
An injector comprising: a housing; a first drive member at least partially disposed within the housing and operable to engage a plunger of a first syringe; a first syringe retaining mechanism associated with the housing, the syringe retaining mechanism adapted to releasably engage the first syringe; a second drive member at least partially disposed within the housing and operable to engage a plunger of a second syringe; a second syringe retaining mechanism associated with the housing, the syringe retaining mechanism adapted to releasably engage the second syringe; a pressure sensing device operably connected to at least one of the first drive member or the second drive member, the pressure sensing device being adapted to measure fluid pressure within at least one of the first syringe and the second syringe when the respective syringe is engaged by the respective drive member; and a control system operably attached to the first drive member, the second drive member, and the pressure sensing device, the control system being configured to individually control the first drive member and second drive member simultaneously, wherein the control system is capable of causing sequential injection or simultaneous injection.
