The present invention relates to a system and method dispensing flows of two or more fluid streams in varying ratios from a fixed ratio piston proportioning pump. The method comprises determining a desired volume of fluid to dispense, determining the total piston displacement amount required to dispense the desired volume of the fluid, measuring a piston displacement amount as the piston moves to determine when the total piston displacement amount has been achieved, and bypassing the fluid at the ingress port or the egress port, preventing the dispense of the fluid while the piston continues to move when the piston displacement amount reaches the total piston displacement amount. Exemplary embodiments include changing chamber volumes to change the ratiometric mixture of two or more fluid streams and using injected fluid as the motive force to move the piston back and forth within the cylinder.

Systems and methods for controlling mixing between one or more fluids are provided. The systems and methods may utilize a vessel comprising one or more zones where the zones are configured to minimize mixing between one or more fluids. Certain systems and methods may utilize a vessel comprising a tortuous flow path. Other systems and methods may utilize a vessel comprising one or more zones.

A device is described that can accept two or more components for mixing and preparing a composition within the device. Once mixed and prepared, the device can deliver the composition to a surgical site. The composition can be a putty-like material that sets over time at the surgical site, such as a hemostatic device or a device for sealing a hole or cavity in bone.
