Letho is a compact radiopharmaceutical injector system for the automatic intravenous infusion of radio drugs or radio tracers. The system allows for the infusion of gamma and beta-emitting molecules in a radiologically safe manner and with maximum control of all critical parametres such as the flow, the amount and the injection time.
The device was created from a collaboration between Comecer and Codan Argus, a leading Swiss company in hospital infusion pumps for traditional medication and chemotherapy.
The technology and know-how of Comecer are associated with a particular infusion pump system (Argus 717V), among the most common and popular of these applications.
The Letho system works in two ways:
At the heart of the device there is a particular cartridge equipped with a double pierceable septum (one for each end). This cartridge is filled using traditional dispensing systems and Comecer fractionators (Febo, Clio, Althea or others) like a normal syringe. A patent application (BO2013A000256) has been filed for the cartridge and the entire system, including the holder (the shielded container that houses the cartridge) and the infuser.
The Letho system is composed of devices that are individually certified as:
