Abstract

A guide is used for the selective catheterism of anatomic structures and for placing therapeutic instruments.

Claims

1-10. -10. (canceled)

11. A guide for catheterism, the body of which is provided at its distal end with an appendage or endpiece having an axisymmetrical three-dimensional shape, around the axis of revolution of the body of said guide, comprising:

means for dissociating said appendage or said endpiece relatively to the body of said guide;

and means for controlling said dissociation means.

12. The guide according to claim 11, wherein the dissociation means associated with the control means allow action in such a way that said appendage or said endpiece is made detachable from the body of said guide in situ or inside the human body.

13. The guide according to claim 11, wherein the dissociation means act by mechanical action.

14. The guide according to claim 11, wherein said appendage or said endpiece is attached to the body of said guide via physico-chemical interactions.

15. The guide according to claim 11, wherein said appendage or said endpiece is attached to the body of said guide with a substance having adhesive properties.

16. The guide according to claim 11, wherein the appendage or said endpiece is deformable or extensible.

17. The guide according to claim 15, wherein said appendage or said endpiece allows transition between a non-deployed state and a deployed state by modification of its shape and/or of its volume.

19. The guide according to claim 11, wherein the dissociation means are formed by a catheter exerting pressure on the appendage or endpiece.

20. The guide according to claim 11, wherein the dissociation means are formed by an internal conduit or channel and one of the open ends of which coincides with the distal end of the guide, the conduit or channel allowing a pressurized fluid to be conveyed.

21. The guide according to claim 11, wherein the axisymmetrical three-dimension shape is ovoidal, spheroidal or ellipsoidal.
