Claims

1-30. -30. (canceled)

31. An apparatus for treating the interior of a blood vessel, comprising:

a first catheter having a proximal end and a distal end with a plurality of spaced apart perforations therebetween;

an occlusion device coupled to the distal end of said first catheter;

means for deploying the occlusion device; and

means for dispensing a treating agent through said perforations proximal of said occlusion device.

32. The apparatus according to claim 31, further comprising

a second catheter movable within said first catheter, said second catheter having at least one perforation adapted to align sequentially with said plurality of spaced apart perforations as said second catheter is moved through said first catheter, said second catheter adapted to receive a treating agent and dispense the treating agent through said at least one perforation.

33. The apparatus according to claim 32, further comprising:

an atraumatic tip coupled to the occlusion device.

34. The apparatus according to claim 32, wherein:

said occlusion device is one of a balloon, a sponge, an umbrella, and a sealant dispenser.

35. The apparatus according to claim 34, wherein:

said occlusion device is an inflatable balloon.

36. The apparatus according to claim 31, wherein:

said perforations are dimensioned to prevent passage of treating fluid until a predetermined fluid pressure is reached.

37. The apparatus according to claim 31, further comprising:

a coaxial cylindrical baffle located within said first catheter and defining an annular space between it and said first catheter.

38. The apparatus according to claim 31, further comprising:

an inflation catheter substantially coaxial with and extending through said first catheter,

wherein

said occlusion device is an inflatable balloon coupled to said inflation catheter.

39. The apparatus according to claim 31, wherein:

said means for deploying includes a first lumen in said first catheter, and

said means for dispensing includes a second lumen in said first catheter.

40. The apparatus according to claim 39, wherein:

said first lumen and said second lumen are coaxial.

41. The apparatus according to claim 39, wherein:

said means for dispensing includes said second lumen and a third lumen in said catheter, said second and third lumena being coupled at their distal ends.

42. The apparatus according to claim 39, wherein:

said first lumen is longer than said second lumen.

43. The apparatus according to claim 31, wherein:

said perforations each have substantially the same diameter.

44. The apparatus according to claim 31, wherein:

at least some of said perforations have different diameters.

45. The apparatus according to claim 31, wherein:

said perforations are evenly spaced.

46. The apparatus according to claim 31, wherein:

at least some of said perforations are variably spaced.

47. The apparatus according to claim 31, wherein;

at least some of said perforations are provided in spaced apart groups.

48. The apparatus according to claim 47, wherein:

said groups are evenly spaced.

49. The apparatus according to claim 47, wherein:

at least some of said groups are variably spaced.

50. The apparatus according to claim 47, wherein:

each of said groups contains the same number of perforations.

51. The apparatus according to claim 47, wherein:

at least some of said groups contain different numbers of perforations.

52. A method for treating the interior of a blood vessel, said method comprising:

delivering an apparatus into the blood vessel, the apparatus having

a first catheter having a proximal end and a distal end with a plurality of spaced apart perforations therebetween,

an occlusion device coupled to the distal end of the first catheter, and

deployment means for deploying said occlusion device;

deploying the occlusion device; and

dispensing a treating agent through the perforations in the first catheter proximal the occlusion device while maintaining the first catheter stationary.

53. The method according to claim 52, wherein:

the apparatus includes

a second catheter movable within the first catheter, the second catheter having at least one perforation adapted to align sequentially with the plurality of spaced apart perforations as the second catheter is moved through the first catheter, the second catheter adapted to receive a treating agent and dispense the treating agent through the at least one perforation, and said method further comprises

withdrawing the second catheter through the first catheter while dispensing treating fluid and maintaining the first catheter stationary.
