RELATED APPLICATION [0001] This application is a continuation of co-pending U.S. application Ser. No. 10/376,068, filed Feb. 26, 2003, which is incorporated herein by reference. FIELD OF TECHNOLOGY [0002] The invention generally pertains to intracorporal medical devices, such as guidewires, catheters, or the like. BACKGROUND [0003] A wide variety of medical devices have been developed for intracorporal use. Elongated medical devices are commonly used in to facilitate navigation through and/or treatment within the anatomy of a patient. Because the anatomy of a patient may be very tortuous, it is desirable to combine a number of performance features in such devices. For example, it is sometimes desirable that the device have a relatively high level of pushability and torqueability, particularly near its proximal end. It is also sometimes desirable that a device be relatively flexible, particularly near its distal end. A number of different elongated medical device structures and assemblies are known, each having certain advantages and disadvantages. However, there is an ongoing need to provide alternative elongated medical device structures and assemblies. SUMMARY OF SOME EMBODIMENTS [0004] The invention provides several alternative designs, materials and methods of manufacturing alternative elongated medical device structures and assemblies. BRIEF DESCRIPTION OF THE DRAWINGS [0005] The invention may be more completely understood in consideration of the following detailed description of various embodiments of the invention in connection with the accompanying drawings, in which: [0006] FIG. 1 is a partial cross sectional fragmentary view of a guidewire in accordance with one example embodiment; [0007] FIG. 2 is a cross sectional fragmentary view of another example embodiment of a guidewire; [0008] FIG. 3 is a cross sectional view of the ribbon of the guidewire of FIG. 1 which is attached to the distal section of the guidewire at a distal attachment point, for example, using solder and radiant heat energy to heat the solder, wherein the dotted lines indicate the area that might be heated using radiant heat energy; [0009] FIG. 4 is a cross sectional view of the ribbon of the guidewire of FIG. 1 which is attached to the distal section of the guidewire at a distal attachment point, for example, using solder and light source energy to heat the solder, wherein the dotted lines indicate the area that might be heated using light source energy; [0010] FIG. 5 is a cross sectional view of the ribbon of the guidewire of FIG. 1 which is attached to the distal section of the guidewire at a distal attachment point, for example, using solder and LASER energy to heat the solder, wherein the dotted lines indicate the area that might be heated using LASER energy; [0011] FIG. 6 is a cross sectional view of the proximal section of the ribbon of the guidewire of FIG. 1 prior to attachment to the distal section of the guidewire at a proximal attachment point, showing an attachment or centering ring, and solder material prior to heating; [0012] FIG. 7 is a cross sectional view of the ribbon of the guidewire of FIG. 6 during heating, showing the solder material flowing or wicking into the attachment points to attach the ribbon to the distal portion of the guidewire and to the attachment or centering ring; [0013] FIG. 8 is a cross sectional view of the ribbon of the guidewire of FIG. 7 after heating, showing the solder attachment points attaching the ribbon to the distal portion of the guidewire and to the attachment or centering ring, and also showing the coil attached to the centering ring; [0014] FIG. 9 is a cross sectional fragmentary view of an example coil construction that can be used in medical devices, the coil construction including an inner coil attached to an outer coil; [0015] FIG. 10 is a cross sectional fragmentary view of another example embodiment of a coil construction wherein an inner coil is connected to an outer coil via an intermediate member; [0016] FIG. 11 is a cross sectional fragmentary view of an another example coil construction that can be used in medical devices, the coil construction including a first coil attached to a second coil; [0017] FIG. 12 is a cross sectional fragmentary view of an example coil configuration that can be used in medical devices, the coil configuration including an inner portion and an outer portion; [0018] FIG. 13 is a cross sectional fragmentary view of a tip construction of a guidewire including the coil configuration of FIG. 12; [0019] FIG. 14 is a cross sectional fragmentary view of an example coil that can be used in medical devices, the coil including a wire including an inner portion made of a first material and an outer portion made of a second material; Continue reading...
