1. A multi-directional needle assembly for injecting substance into at least one injection site of a patient'"'"'s body, comprising:

  • c. an elongated member having a distal end;

    said distal end having a plurality of openings disposed therein; and

    ,d. a plurality of needles disposable at least partially within said elongated member, said needles adapted to be reconfigured from a FOLDED configuration to a DEPLOYED configuration and vice versa;

    said FOLDED configuration being characterized by the position of said plurality of needles within said elongated member;

    said DEPLOYED configuration being characterized by the protrusion of said needles out of said plurality of openings;

    , (ii) a DEAD AREA between said two separated areas is obtained, wherein at least one of the following is being held true;

    (i) said DEAD AREA is characterized by a solid angle of at least at least about 1 steradian;

    (ii) said DEAD AREA is characterized by a spreading angle in the range of 20 to 60 degrees from each other;

    (iii) said DEAD AREA is characterized by a maximal length of at least 0.1 nanometer;

    or,(iv) said DEAD AREA is characterized by a geometrical area of at least 0.1 nanometer2;

    (v) said DEAD AREA is characterized by a cross sectional area of at least 0.1 nanometer2;
