A method for assembling a liner (10) in a tube (12) includes placing a liner (10) in a tube (12), and heating a portion of the liner (10), called a heated portion (18), with a local heat source (16). The heated portion (18) is not more than a third of a total length of the liner. The heated portion (18) is expanded radially outwards so that the heated portion (18) abuts against an inner wall of the tube (12). The local heat source is repeatedly advanced longitudinally along a desired length of the liner to expand the heated portion (18) radially outwards so that the heated portion (18) abuts against the inner wall of the tube (12) for the desired length.

A steering tool includes an internal tube disposed inside an external tube. The internal and external tubes are arranged for longitudinal axial movement relative to one another. A distal end of the internal tube is fixedly joined to a distal end of the external tube. At least one of the internal and external tubes is slotted near the distal end thereof, and the longitudinal axial movement causes bending of the distal ends of the tubes.
A steering tool includes an internal tube (32) disposed inside an external tube (34). The internal and external tubes (32, 34) are arranged for longitudinal axial movement relative to one another. A distal portion of the internal tube (32) is fixedly joined to a distal portion of the external tube (34). Either or both of the tubes are formed with patterns of cuts made along adjacent longitudinal stations along a length of the cut tube (10). The cutting pattern at one longitudinal station (12, 14, 16) is shifted with respect to a cutting pattern at a previous longitudinal station, so that a shift from one longitudinal station of cuts to the next adjacent longitudinal station of cuts is not repeated.

A method of changing a catheter into a distal steering tool catheter includes adding to an existing catheter a tube assembly that passes through the catheter, the tube assembly including an internal tube and an external tube whose distal ends are coupled to each other and which are arranged for longitudinal axial movement relative to one another, and providing a tube manipulator coupled to the tube assembly, which is operative to cause relative axial movement of the internal and external tubes and bending of a distal portion of at least one of the internal and external tubes.

A steering tool includes an internal tube disposed inside an external tube. The internal and external tubes are arranged for longitudinal axial movement relative to one another. A distal portion of the internal tube is fixedly joined to a distal portion of the external tube. Either or both of the tubes are formed with patterns of cuts made along adjacent longitudinal stations along a length of the cut tube. The cutting pattern at a first longitudinal station is shifted with respect to a cutting pattern at a second longitudinal station and a cutting pattern at the second longitudinal station is shifted with respect to a cutting pattern at a third longitudinal station but at a different shift defined between the first and second longitudinal stations, so that a shift from one longitudinal station of cuts to the next adjacent longitudinal station of cuts is not repeated.
A method of changing a catheter (1) into a distal steering tool (10) catheter includes adding to an existing catheter a tube assembly that passes through the catheter, the tube assembly including an internal tube (12) and an external tube (14) whose distal ends are coupled to each other and which are arranged for longitudinal axial movement relative to one another, and providing a tube manipulator (18) coupled to the tube assembly, which is operative to cause relative axial movement of the internal and external tubes and bending of a distal portion of at least one of the internal and external tubes.
A steering tool includes an internal tube disposed inside an external tube. The internal and external tubes are arranged for longitudinal axial movement relative to one another. A distal portion of the internal tube is fixedly joined to a distal portion of the external tube. At least one of the tubes may include, over at least some of its length, two continuous, longitudinal zones of solid material separated from each other by a longitudinal gap. At least one of the tubes may include a flexible distal portion distal to the joining zone, the flexible distal portion being more flexible than other portions of that tube.

A steering tool (70) includes an internal tube (12) disposed inside an external tube (14). The internal and external tubes (12,14) are arranged for longitudinal axial movement relative to one another. A distal end of the internal tube (12) is fixedly joined to a distal end of the external tube (14). A tube manipulator (70) can cause relative axial movement and distal bending of the internal and external tubes (12,14). A locking mechanism (72) can switch between a locked position in which the internal and external tubes (12,14) are locked at a particular longitudinal axial position relative to one another, and an unlocked position in which there is uninhibited free movement of the internal and external tubes (12,14) relative to one another. The locking mechanism (72) also includes an intermediate locked position in which there is partially inhibited movement of the internal and external tubes (12,14) relative to one another.
