b) a plurality of flexible arms removably coupled to said platform and extending therefrom, said arms each capable of being fixed in a tortuous path and each having a proximal arm mount and a distal grasping means for grasping the respective medical devices;

wherein said platform includes a first side disposed opposite a second side, said first side including first attachment means for removable direct coupling to an arm mount of one of said plurality of arms, said second side including second attachment means for removable direct coupling to an arm mount of another of said plurality of arms, and the arm mount of each one of said plurality of arms defining a third side opposite a fourth side, said third and fourth sides including third and fourth attachment means, respectively, that are adapted for removable direct coupling to said first and second attachment means of said platform as well as for removable direct coupling to an arm mount of another arm of the assembly.

2. The medical assembly according to claim 1 , wherein:

each arm comprises a plurality of links.

3. The medical assembly according to claim 2 , wherein:

each of said plurality of links includes a socket, and

each arm comprises a plurality of ball-type joints which engage a respective link socket.

4. The medical assembly according to claim 1 , wherein:

each arm includes a tension cable.

5. The medical assembly according to claim 4 , wherein:

each arm includes means for tightening and loosening said cable.

6. The medical assembly according to claim 4 , wherein:

said means for tightening and loosening comprises a winch mechanism which is coupled to a proximal end of said cable and which rotates to cause translational movement of said cable.

7. The medical assembly according to claim 4 , wherein:

said means for tightening and loosening comprises a knob and threaded means coupled to said knob and to said cable, said threaded means for translating rotation of said knob into translational movement of said cable.

8. The medical assembly according to claim 1 , wherein:

each said grasping means includes handles, opposed grasping elements coupled to said handles, and a proximal connector which is coupled to a respective arm.

9. A medical assembly according to claim 8 , wherein:

each said grasping means is a one piece molded unit.

10. The medical assembly according to claim 8 , wherein:

each said arm includes a cable, and

said proximal connector defines a socket which receives said arm and a chamber which captures a distal end of said cable.

11. The medical assembly according to claim 10 , further comprising:

a spring around said distal end of said cable and captured in said chamber.

12. The medical assembly according to claim 1 , wherein:

said first attachment means comprises a first rail;

said second attachment means comprises a first slot;

said third attachment means comprises a second rail; and

said fourth attachment means comprises a second slot;

wherein said second rail is adapted to be slidably received within said first slot for removable direct coupling of a respective arm mount to said platform or slidably received within a second slot of another respective arm mount for removable direct coupling of a pair of arm mounts; and

wherein said second slot is adapted to slidably receive said first rail for removable direct coupling of a respective arm mount to said platform or slidably receive a second rail of another arm mount for removable direct coupling of a pair of arm mounts.

13. The medical assembly according to claim 1 , wherein:

said coupling means of said platform provides for relative movement of said platform relative to said fixture.

14. The medical assembly according to claim 1 , wherein:

said coupling means of said platform comprises a pole; and

said platform defines a central hole for receiving said pole.

15. The medical assembly according to claim 14 , wherein:

said coupling means of said platform further comprises a knob extending through a second hole in said platform orthogonal to said central hole, said knob for fixing said platform relative to said pole.

16. A method for holding a plurality of medical devices extending into a patient in fixed positions relative to a patient, said method comprising:

a) providing an assembly including a platform and a plurality of flexible arms, the platform having coupling means for coupling to a fixture that supports the platform, the plurality of flexible arms capable of being removably coupled to the platform and extending therefrom, said arms each capable of being fixed in a tortuous path and each having a proximal arm mount and a distal grasping means for grasping the respective medical devices, wherein the platform includes a first side disposed opposite a second side, said first side including first attachment means for removable direct coupling to an arm mount of one of said plurality of arms, said second side including second attachment means for removable direct coupling to an arm mount of another of said plurality of arms, and the arm mount of each one of said plurality of arms defining a third side opposite a fourth side, said third and fourth sides including third and fourth attachment means, respectively, that are adapted for removable direct coupling to said first and second attachment means of said platform as well as for removable direct coupling to an arm mount of another arm of the assembly;

b) coupling the platform to a fixture such that the platform is supported by the fixture;

c) removably coupling a respective arm mount for one of the plurality of arms directly to the platform using the first attachment means of the platform and one of the third and fourth attachment means of the respective arm mount;

d) removably coupling a respective arm mount for another of the plurality of arms directly to the platform using the second attachment means of the platform and one of the third and fourth attachment means of the respective arm mount;

e) manipulating the arms whose arm mounts where removably coupled to the platform in c) and d) into desired positions; and

f ) manipulating the graspers of the arms whose arm mounts where removably coupled to the platform in c) and d) in order to grasp the respective medical devices.

17. The method according to claim 16 , further comprising:

h) removably coupling at least one arm mount for an additional arm directly to at least one of the arm mounts removably coupled to the platform in c) and d) using one of the third and fourth attachment means of the at least one arm mount of the additional arm.

18. The method according to claim 17 , wherein:

the arm mounts are held in positions offset laterally from the platform.

19. The method according to claim 16 , further comprising:

g) removably coupling a respective arm mount for an additional arm directly to one of the arm mounts removably coupled to the platform in c) using one of the third and fourth attachment means of the respective arm mount.

20. The method according to claim 16 , further comprising:

after said manipulating of e), applying tension to the arms whose arm mounts where removably coupled directly to the platform in c) and d) in order to fix such arms in the desired positions.

21. The method according to claim 16 , wherein:
