9 . As in claim 1 , wherein said flexible pilot wire comprises a hollow tube with an inflatable chamber attached to its distal end section, said chamber being inflatable through said hollow tube.
Claim 11
Dependent Claim
31 words
10 . As in claim 1 , wherein the flexible guidewire system is disposed in a sleeve with a biasing means to deflect the position of said casing in said vessel.
Claim 12
Dependent Claim
20 words
11 . As in claim 10 , wherein said biasing means comprises a sleeve with a curved distal end section.
Claim 13
Dependent Claim
28 words
12 . As in claim 10 , wherein said biasing means comprises a sleeve with a selectively inflatable chamber attached to said distal end section of said sleeve.
Claim 14
Dependent Claim
81 words
13 . A process for crossing an obstruction in a patient's vessel comprising the following steps: inserting through the vessel, to an obstruction, a flexible pilot wire, advancing through the vessel, over the pilot wire, a flexible tubular casing with at least a distal portion being a helical wire having a gated distal end and a coupling means for connecting said casing to a drive means, threading the casing through the obstruction by advancing and rotating it over the pilot wire.
Claim 15
Dependent Claim
81 words
13 . A process for crossing an obstruction in a patient's vessel comprising the following steps: inserting through the vessel, to an obstruction, a flexible pilot wire, advancing through the vessel, over the pilot wire, a flexible tubular casing with at least a distal portion being a helical wire having a gated distal end and a coupling means for connecting said casing to a drive means, threading the casing through the obstruction by advancing and rotating it over the pilot wire.
