Abstract

A dispensing device which disperses medicate through a needle across a zone within a body. The device includes a needle which is, during use, becomes encapsulated within a tubular needle-receiving member, a reservoir in fluid communication with the needle, positioned within the housing, and in communication with the needle, a second reservoir, a reservoir-connecting conduit in communication with the reservoir, a fluid drive in communication with the fluid in the second reservoir and in communication with the reservoir-connecting conduit, and a linear drive attached to the needle or to the needle-receiving member. The fluid drive impel fluids from the second reservoir to the reservoir-connecting conduit and thus drives the therapeutic agent from the reservoir during the linear displacement of the needle towards the housing. Fluid communication from the therapeutic agent reservoir to the needle is maintained by the tubing during operation of the linear drive.

Claims

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.

2. The distributed injection device of claim 1 further comprising

a slide member, said needle fixed in position at a first end of said slide member,

said slide member slidably positioned within said receiving member;

and

said linear drive connected to said slide member.
