Disclosed is an improved pointed instrument for insertion into blood vessels where an occlusion arises or terminates too closely to the insertion site for proper sheath placement. The pointed instrument exhibits supportive characteristics that allow for a sheath to be placed in an otherwise inaccessible insertion site. One embodiment of the present disclosure features a pointed instrument having a flexible portion, which is generally straight outside the body, but agglomerates once inside a blood vessel.
