WHAT IS CLAIMED IS:

1. A needle guide for guiding the insertion of a needle in a patient, said needle guide comprising:

- a base element, said base element including an abutment section for abutting against said patient and a spacer extending from said abutment section; and

- a guiding element, said guiding element defining at least one guiding aperture extending therethrough for inserting said needle therethrough;

- said guiding element being removably attachable to said spacer and movable between a distal position and a proximal position, wherein, in said distal position, said guiding element is attached to said spacer in a spaced apart relationship relatively to said abutment section, and, in said proximal position, said guiding element is detached from said spacer and substantially adjacent to said base element.

2. A needle guide as defined in claim 1 , wherein said abutment section defines a base aperture extending therethrough, said guiding aperture and said base aperture being substantially in register with each other when said guiding element is in said proximal position.

3. A needle guide as defined in claim 2, wherein said guiding aperture and said base aperture are substantially in register with each other when said guiding element is in said distal position.

4. A needle guide as defined in claim 2, wherein said base aperture has a larger diameter than said guiding aperture.

5. A needle guide defined in claim 2, wherein said needle guide is configured and sized so that said needle is insertable simultaneously through both of said guiding and base apertures when said guiding element is in said distal and proximal positions.

6. A needle guide defined in claim 5, wherein said needle guide is configured and sized so that said guiding element is movable between said proximal and distal positions with said needle inserted simultaneously through both said guiding and base apertures.

7. A needle guide as defined in claim 1 , wherein said guiding element defines a plurality of guiding aperture extending therethrough each for selectively inserting said needle therethrough.

8. A needle guide as defined in claim 7, wherein said guiding element defines a guiding element peripheral edge, said plurality of guiding apertures including a first guiding aperture having a first diameter and a second guiding aperture having a second diameter, said first guiding aperture being closer to said guiding element peripheral edge than said second guiding aperture and said first diameter being larger than said second diameter.

9. A needle guide as defined in claim 1 , wherein said guiding element is substantially plate-shaped.

10. A needle guide as defined in claim 1 , wherein said guiding element and said spacer are attachable to each other in a press-fit relationship relatively to each other.

11. A needle guide as defined in claim 1 , wherein said spacer defines a pin protruding therefrom and said guiding element defines an attachment hollow for receiving said pin when said spacer and guiding element are attached to each other.

12. A needle guide as defined in claim 11 , wherein said attachment hollow extends through said guiding element and said pin protrudes from said attachment hollow when said guiding element is attached to said spacer.

13. A needle guide as defined in claim 1 , wherein said spacer defines a pin protruding therefrom and said guiding element defines at least two attachment hollows each for selectively and alternatively receiving said pin when said spacer and guiding elements are attached to each other.

14. A needle guide as defined in claim 1 , wherein said abutment section is substantially plate-shaped.

15. A needle guide as defined in claim 1 , wherein said guiding aperture defines a substantially frusto-conical portion.

16. A needle guide as defined in claim 1 , wherein said abutment section is substantially plate-shaped and defines an abutment section proximal surface for abutting against said patient and a substantially opposed abutment section distal surface, said abutment section also defining a base aperture extending therethrough between said abutment section proximal and distal surfaces.

17. A needle guide as defined in claim 16, further comprising another spacer, both of said spacers extending from said abutment section distal surface.

18. A needle guide as defined in claim 17, wherein said spacers are provided substantially opposed to each other with respect to said base aperture.

19. A needle guide as defined in claim 18, wherein said guiding element is located between said spacers in said proximal position.

20. A needle guide as defined in claim 19, wherein said guiding element is substantially plate-shaped.

21. A needle guide as defined in claim 1 , wherein said abutment section is provided with an adhesive for adhesively attaching said abutment section to said patient.

22. A needle guide as defined in claim 1 , further comprising a lock for reversibly locking said guiding element and said spacer to each other when said guiding element and said spacer are attached to each other with said guiding element in said distal position.

23. A needle guide as defined in claim 1 , wherein said guiding element defines a plurality of guiding apertures extending therethrough each for selectively inserting said needle therethrough, said guiding apertures being arranged in substantially grid-like configuration.

24. A method for inserting a needle in a patient using a needle guide, said needle guide comprising a base element and a guiding element defining a guiding aperture, said method comprising:

- securing said base element to said patient;

- attaching said guiding element to said base element with said guiding element in a substantially spaced apart relationship relatively to said patient;

- inserting said needle through said guiding aperture and into said patient at a first needle position;

- detaching said guiding element from said base element and moving said guiding element toward said patient;

- after moving said guiding element toward said patient, inserting said needle into said patient at a second needle position, said second needle position differing from said first needle position.

25. A method as defined in claim 24, wherein said second needle position is deeper than said first needle position.

26. A method as defined in claim 24, wherein in said first and second needle positions, said needle and said patient are in different angular positional relationships relative to each other.

27. A method as defined in claim 24, wherein said base element defines a base aperture extending therethrough, inserting said needle through said guiding aperture and into said patient at said first needle position including inserting said needle through said base aperture.

28. A method as defined in claim 24, further comprising detaching said guiding element from said base element and reattaching said guiding element to said base element so as to change a relative positional relationship between said base and guiding elements.

29. A method as defined in claim 24, wherein said needle remains inserted in said patient when detaching said guiding element from said base element and moving said guiding element toward said patient.

30. A needle guide for guiding the insertion of a needle in a patient, said needle guide comprising:

- a base element attachable to said patient; and

- a guiding element, said guiding element defining at least one guiding aperture extending therethrough for inserting said needle therethrough;

- said guiding element being movable between a distal position and a proximal position, wherein, in said distal position, said guiding element is attached to said base element in a spaced apart relationship relatively to said base element, and, in said proximal position, said guiding element is closer to said patient than in said distal position.

31. A needle guide for guiding the insertion of a needle in a patient, said needle guide comprising:

- a base element, said base element including an abutment section for abutting against said patient and a spacer extending from said abutment section; and

- a guiding element, said guiding element defining at least one guiding aperture extending therethrough for inserting said needle therethrough;

- said guiding element being removably attachable to said spacer in at least two different relative positional relationships between said base and guiding elements.

32. A needle guide as defined in claim 31 , wherein said guiding element is substantially plate-shaped and said guiding element remains substantially coplanar with itself when moved between said at least two different relative positional relationships.

33. A needle guide as defined in claim 31 , wherein said at least two different relative positional relationships between said base and guiding elements are spatially spaced apart by discrete distance increments.
