Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
77 words
A wire guide having a flexible distal tip and adapted for guiding a catheter within a body blood vessel, comprising: a helically wound wire having a longitudinal opening; a mandril positioned within said opening and longitudinally movable therein relative to said wire for varying the flexibility of said distal tip of said wire guide and, a coating of lubricating material coating the outer surface of said mandril and facilitating smooth movement of said mandril within said opening.
Claim 2
Dependent Claim
77 words
A wire guide having a flexible distal tip and adapted for guiding a catheter within a body blood vessel, comprising: a helically wound wire having a longitudinal opening; a mandril positioned within said opening and longitudinally movable therein relative to said wire for varying the flexibility of said distal tip of said wire guide and, a coating of lubricating material coating the outer surface of said mandril and facilitating smooth movement of said mandril within said opening.
Claim 3
Dependent Claim
22 words
The apparatus of claim 1 wherein the distal portion of said mandril is tapered inwardly towards the distal end of said mandril.
Claim 4
Dependent Claim
48 words
The apparatus of claim 2 wherein said mandril includes an enlarged bulb at the distal end, said bulb permitting said wire to be curved and said mandril to be advanced relative to the distal end of said wire without said mandril protruding through the coils of said wire.
Claim 5
Dependent Claim
33 words
The apparatus of claim 3 wherein said bulb has a diameter approximately equal to the diameter of the untapered portion of said wire and a length which is 2-5 times said wire diameter.
Claim 6
Dependent Claim
34 words
The apparatus of claim 4 wherein said helically wound wire is coated on its outer surface with a lubricating material, said lubricating material facilitating smooth movement of said wire guide through said blood vessel.
Claim 7
Dependent Claim
11 words
The apparatus of claim 5 wherein said lubricating material is Teflon.
