Abstract
Abstract The present invention is a device and method for controlling longitudinal movement of a tube relative to a shaft slidably disposed within the tube, especially in the catheterization of a patient. An operative segment on the shaft cooperates with an ancillary tool to create a coupling force field between the shaft and the tool. The tube can then be moved over the shaft while the coupling force field operates through the tube to restrict the movement of the shaft. In preferred embodiment, the shaft is a guide wire and the tube is a catheter with a lumen for slidably receiving the guide wire, while the coupling force field is created magnetically. In one embodiment, the operative segment is borne on a short guide wire extension which is selectively securable to a standard guide wire.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
113 words
An apparatus for cooperating with a catheter assembly, the assembly including a catheter having a longitudinal lumen and a shaft insertable in the lumen, comprising: a. a housing for holding a proximal end of the catheter assembly against lateral motion, the housing having a longitudinal catheter receiving groove therein, the groove having a proximal end and a distal end and a longitudinally extending side opening therebetween through which the proximal end of the catheter can be placed into the groove; and b. be a device for generating a differential holding force within the housing capable of preventing longitudinal motion of the shaft of the catheter assembly while allowing longitudinal motion of the catheter.
Claim 2
Independent Claim
113 words
An apparatus for cooperating with a catheter assembly, the assembly including a catheter having a longitudinal lumen and a shaft insertable in the lumen, comprising: a. a housing for holding a proximal end of the catheter assembly against lateral motion, the housing having a longitudinal catheter receiving groove therein, the groove having a proximal end and a distal end and a longitudinally extending side opening therebetween through which the proximal end of the catheter can be placed into the groove; and b. be a device for generating a differential holding force within the housing capable of preventing longitudinal motion of the shaft of the catheter assembly while allowing longitudinal motion of the catheter.
Claim 3
Dependent Claim
16 words
An apparatus according to claim 1 further comprising an operator handle fixedly attached to the housing.
Claim 4
Dependent Claim
21 words
An apparatus according to claim 2 wherein the operator handle further comprises a coupler for slidable attachment to the catheter assembly.
Claim 5
Dependent Claim
23 words
An apparatus according to claim 1 wherein the shaft is a guide wire and the catheter is slidably located over said guide wire.
Claim 6
Dependent Claim
40 words
An apparatus according to claim 4 wherein the guide wire has a distal end and a proximal end and wherein the proximal end of the guide wire includes an active area which is prevented from longitudinal motion by the device.
Claim 7
Dependent Claim
79 words
A tool, comprising: a housing including an elongated block having a longitudinal channel therein; an elongated second block held in the channel, and having a groove configured to receive a catheter having a longitudinal lumen with a guide wire having an operable portion slidably placed in the lumen; and a permanent magnet retained between the first and second blocks so that the operable portion of the guide wire can be held by a magnetic field created by the magnet.
Claim 8
Dependent Claim
79 words
A tool, comprising: a housing including an elongated block having a longitudinal channel therein; an elongated second block held in the channel, and having a groove configured to receive a catheter having a longitudinal lumen with a guide wire having an operable portion slidably placed in the lumen; and a permanent magnet retained between the first and second blocks so that the operable portion of the guide wire can be held by a magnetic field created by the magnet.
Claim 9
Dependent Claim
14 words
A tool in accordance with claim 6, wherein the magnet is a permanent magnet.
Claim 10
Dependent Claim
35 words
A tool in accordance with claim 7, comprising a plurality of spaced apart permanent magnets configured to correspond with a plurality of spaced apart magnetically permeable portions of the operable portion of the guide wire.
Claim 11
Dependent Claim
17 words
A tool in accordance with claim 7, wherein the magnets are spaced apart by a uniform distance.
Claim 12
Dependent Claim
16 words
A tool in accordance with claim 7, wherein the polarity of every other magnet is reversed.
Claim 13
Dependent Claim
30 words
The tool in accordance with claim 6, further comprising a handle operably connected to the housing at a first end and including a catheter receiving element at a second end.
Claim 14
Dependent Claim
24 words
The tool in accordance with claim 11, wherein the catheter receiving element is configured to engage with a Y-adaptor operably connected to the catheter.
Claim 15
Dependent Claim
34 words
A catheter in accordance with claim 12, wherein the handle extends generally parallel to the groove and the adaptor is configured to hold the Y-adaptor in an approximately longitudinal axial alignment with the groove.
Claim 16
Dependent Claim
18 words
A tool in accordance with claim 13, wherein the first block, second block and handle are molded polycarbonate.
