1. A distributed injection device, comprising
a needle, said needle having an attachment end and an injection end, said needle having a needle outer diameter, and said needle having an internal cross-sectional area, said needle having a needle longitudinal axis;
a housing including a needle-receiving member, said needle-receiving member being tubular, said needle-receiving member having an open first end, said needle-receiving member having a needle-receiving member inner diameter, said needle-receiving member inner diameter greater than said needle outer diameter, said needle-receiving member having a needle-receiving member longitudinal axis, said needle longitudinal axis and said needle-receiving member longitudinal axis generally parallel, said needle-receiving member circumscribing said needle longitudinal axis;
a reservoir adapted to contain a therapeutic agent, said therapeutic agent reservoir in fluid communication with said needle via a tubing, said therapeutic agent reservoir positioned within said housing;
a second reservoir adapted to contain fluid;
a reservoir-connecting conduit, said reservoir-connecting conduit in communication with said therapeutic agent reservoir;
a bidirectional fluid drive in communication with said fluid in said second reservoir, said bidirectional fluid drive in communication with said reservoir-connecting conduit; and
a linear drive associated with said needle or said needle-receiving member;
said linear drive adapted to provide a linear displacement of said needle towards said housing, or to provide a linear displacement of said needle-receiving member away from said housing;
a computer in communication with said bidirectional fluid drive and with said linear drive;
wherein said bidirectional fluid drive adapted to impel fluid from said second reservoir to said reservoir-connecting conduit and to drive said therapeutic agent from said therapeutic agent reservoir after said linear displacement of said needle towards said housing; and
wherein said fluid communication from said therapeutic agent reservoir to said needle is maintained by said tubing during operation of said linear drive to provide a linear displacement of said needle towards said housing, or to provide a linear displacement of said needle-receiving member away from said housing.
