1. A shapable medical apparatus comprising, in combination:

  • a core wire having a distal portion with a predetermined non-linear shape; and

    a catheter having a lumen proportioned to slidably receive the core wire, the catheter including a proximal section and a distal section, the distal section having greater flexibility than the proximal section, the core wire slidably receivable within the lumen such that when the core wire is introduced into the proximal section of the catheter, said distal portion is substantially straightened by the proximal section of the catheter, and when said core wire is advanced so that at least a portion of the distal portion is within the distal section of the catheter, the catheter is deformed to approximate the non-linear shape of the portion of the distal portion of the core wire that is within the distal section.
