What Medisystem does

Medisystem is a French radiation protection equipment brand specializing in nuclear medicine applications. The company offers a focused portfolio of shielded devices covering the full radiopharmaceutical lifecycle—from reception and preparation through injection, imaging, and radioactive waste management—across all relevant radiation energy ranges (high-energy PET, low-to-medium-energy SPECT, and alpha/beta shielding). Named proprietary products include the Posijet® automated high-energy preparator/injector, the Theranojet®ARA shielded enclosure for theranostic injection pumps, the Valisette Shellbox shielded syringe transport case, the Easypharma® 4R and Compact shielded preparation enclosures, the Epijet® specialized epilepsy imaging injector, and the registered Novashield® radiation shielding product range for nuclear industry and research.

The underlying technology rests on engineered leaded shielding (leaded glass, attenuating materials for gamma, neutron, alpha, and beta radiation), integrated mechanical and ergonomic design, and—for connected products such as Posijet®—Wi-Fi-enabled control interfaces. Medisystem operates as a product brand within the Lemer Pax portfolio, with Lemer Pax (headquartered in La Chapelle-sur-Erdre, near Nantes) providing the commercial infrastructure, distribution, custom engineering, radioprotection study services (shielding calculations, dosimetry, 3D modeling), maintenance, and customer support for Medisystem-branded products alongside its own branded offerings.

Medisystem generates revenue primarily through one-time capital equipment sales to healthcare institutions—including nuclear medicine departments, radiopharmacies, hospitals, and academic research centers—supplemented by maintenance, support, and custom development services. The go-to-market model is consultative enterprise field sales targeting radiopharmacists, nuclear medicine department heads, and radiological protection officers, with project-specific quotations driven by facility requirements, energy level specifications, and regulatory compliance scope. The customer base is international, with documented deployments in France, Switzerland, Denmark, Spain, Greece, the UK, and the Caribbean.
