| abstract |
This invention is an applicator particularly suited for dispensing a range of different tissue sealants, for example fibrin sealants with different setting times, conditioning agents or therapeutic agents, having a manual selector (48) for user to select different outputs. Various differential drive mechanisms are disclosed for selectively dispensing different concentrations of fluids optionally with internal mixing from two or three more fluid sources, such as fluid reservoirs (24, 26, 28) carried by an applicator. Interchangeable reservoirs, and the option of controlling concentration by discharging one reservoir to waste, are also disclosed. |
