9 . The method of claim 1 , wherein associating the rigidifying agent with the distal end portion of the elongated member includes maintaining the rigidifying agent in the distal end portion of the elongated member at up to 20% of the weight of the elongated member.
10 . The method of claim 1 , wherein associating the rigidifying agent with the distal end portion of the elongated member includes associating a biocompatible thermoplastic polymer with the distal end portion of the elongated member.
11 . The method of claim 10 , wherein associating the rigidifying agent with the distal end portion of the elongated member includes associating a polymer with the distal end portion of the elongated member that is selected from the group consisting of cyanoacrylate monomers, isocyanates, silicones, and ultraviolet polymerizable polyacrylates.
12 . The method of claim 1 , wherein applying energy to the distal end portion of the elongated member and mechanically reconfiguring the distal end portion of the elongated member include compression molding the distal end portion of the elongated member.
13 . The method of claim 12 , wherein compression molding the distal end portion of the elongated member includes placing the distal end portion of the elongated member into a first cavity defined by a first mold portion, and bringing a second mold portion defining a second cavity into juxtaposition with the first mold portion, wherein the first and second cavities are substantially similar in configuration.
14 . The method of claim 12 , wherein compression molding the distal end portion of the elongated member includes placing the distal end portion of the elongated member into a first cavity defined by a first mold portion, and bringing a second mold portion defining a second cavity into juxtaposition with the first mold portion, wherein the first and second cavities are dissimilar in configuration.
15 . The method of claim 12 , wherein compression molding the distal end portion of the elongated member includes reconfiguring the distal end portion of the elongated member so as to define a tapered configuration.
