Abstract
Abstract A catheter system includes a guide wire, a working catheter and a torque device for removably coupling the working catheter to the guide wire while enabling rotation of the guide wire to the working catheter. Advancement of the guide wire in a vascular system is enabled by rotating the guide wire while the working catheter is coupled thereto. A procedure for use of the catheter system includes the simultaneous insertion of the guide wire and working catheter into a vascular system and independent rotation of the guide wire for steering the guide wire, with working catheter coupled thereto, through the vascular system.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
95 words
A catheter system for use with a guide wire having a proximal and a distal end, said catheter system comprising: a working catheter adapted for sliding over said guide wire within a vascular system; a torquing device including means, removably coupling said torquing device to the guide wire, for rotating the guide wire within the working catheter and for sliding the guide wire within the working catheter; and coupling means for removably coupling said torquing device with the working catheter to prevent sliding therebetween without limiting rotatability of the guide wire within the working catheter.
Claim 2
Dependent Claim
95 words
A catheter system for use with a guide wire having a proximal and a distal end, said catheter system comprising: a working catheter adapted for sliding over said guide wire within a vascular system; a torquing device including means, removably coupling said torquing device to the guide wire, for rotating the guide wire within the working catheter and for sliding the guide wire within the working catheter; and coupling means for removably coupling said torquing device with the working catheter to prevent sliding therebetween without limiting rotatability of the guide wire within the working catheter.
Claim 3
Dependent Claim
22 words
The catheter system according to claim 1 wherein said torquing device and coupling means are disposed near the guide wire proximal end.
Claim 4
Dependent Claim
41 words
The catheter system according to claim 2 wherein said torquing device includes a compressible member having means, defining an opening, for enabling passage of said guide wire and fluid therethrough when said compressible member is not compressed onto the guide wire.
Claim 5
Dependent Claim
112 words
A catheter system comprising: a guide wire having a proximal and a distal end, said distal end including means for enabling steering of said guide wire through a vascular system by rotation of the guide wire therein; a working catheter adapted for sliding over said guide wire within the vascular system; a torquing device including means, removably coupling said torquing device to the guide wire, for rotating the guide wire within the working catheter and for sliding the guide wire within the working catheter; and coupling means for removably coupling said torquing device with the working catheter to prevent sliding therebetween without limiting rotatability of the guide wire within the working catheter.
Claim 6
Dependent Claim
112 words
A catheter system comprising: a guide wire having a proximal and a distal end, said distal end including means for enabling steering of said guide wire through a vascular system by rotation of the guide wire therein; a working catheter adapted for sliding over said guide wire within the vascular system; a torquing device including means, removably coupling said torquing device to the guide wire, for rotating the guide wire within the working catheter and for sliding the guide wire within the working catheter; and coupling means for removably coupling said torquing device with the working catheter to prevent sliding therebetween without limiting rotatability of the guide wire within the working catheter.
Claim 7
Dependent Claim
22 words
The catheter system according to claim 4 wherein said torquing device and coupling means are disposed near the guide wire proximal end.
Claim 8
Dependent Claim
41 words
The catheter system according to claim 5 wherein said torquing device includes a compressible member having means, defining an opening, for enabling passage of said guide wire and fluid therethrough when said compressible member is not compressed onto the guide wire.
