A multi-directional needle assembly for injecting substance into at least one injection site of a patient's body, comprising: a. an elongated member having a distal end; said distal end having a plurality of openings disposed therein; and, b. 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; the disposition of said openings in said distal end is provided according to a predetermined scattering pattern such that (i) at least two separated areas (30, 32) having more than three openings per area within said distal end are provided for simultaneous injection of said substance into at least two different injection locations (40, 42) at said injection site; and, (ii) a DEAD AREA between said two separated areas (30, 32) is obtained, wherein at least one of the following being held true: (i) said DEAD AREA having a solid angle of at least at least about 1 steradian; (ii) said DEAD AREA having a spreading angle in the range of 20 to 60 degrees from each other; (iii) said DEAD AREA having a maximal length of at least 0.1 nanometer; (iv) said DEAD AREA having a geometrical area of at least 0.1 nanometer 2; (v) said DEAD AREA having a cross sectional area of at least 0.1 nanometer 2; wherein in said DEPLOYED configuration, said needles are adapted to form at least two injection surfaces at said at least two separated areas (30, 32), each of said at least two injection surfaces is adapted to conform to the anatomical shape of said at least two injection locations (40, 42), the two injection locations (40, 42) being the upper lip and the lower lip of the uterine cervix of female mammals, and wherein said needles are flexible. a. an elongated member having a distal end; said distal end having a plurality of openings disposed therein; and, b. 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; the disposition of said openings in said distal end is provided according to a predetermined scattering pattern such that (i) at least two separated areas (30, 32) having more than three openings per area within said distal end are provided for simultaneous injection of said substance into at least two different injection locations (40, 42) at said injection site; and, (ii) a DEAD AREA between said two separated areas (30, 32) is obtained, wherein at least one of the following being held true: (i) said DEAD AREA having a solid angle of at least at least about 1 steradian; (ii) said DEAD AREA having a spreading angle in the range of 20 to 60 degrees from each other; (iii) said DEAD AREA having a maximal length of at least 0.1 nanometer; (iv) said DEAD AREA having a geometrical area of at least 0.1 nanometer 2; (v) said DEAD AREA having a cross sectional area of at least 0.1 nanometer 2; wherein in said DEPLOYED configuration, said needles are adapted to form at least two injection surfaces at said at least two separated areas (30, 32), each of said at least two injection surfaces is adapted to conform to the anatomical shape of said at least two injection locations (40, 42), the two injection locations (40, 42) being the upper lip and the lower lip of the uterine cervix of female mammals, and wherein said needles are flexible.
