1. A tool for manipulating a guidewire, comprising:
- an elongated body having a bore extending therethrough and a longitudinal slot extending radially from said bore through the surface of said elongated body, said slot and said bore being adapted to receive the guidewire;
one end of said elongated body including a collet portion, said collet portion having a plurality of radial, longitudinally extending slots extending from said elongated bore through the surface of said collet portion, a portion of said surface of said collet portion being threaded; and
a nut threadably mounted to said collet portion and having a bore extending therethrough, said nut having a radial, longitudinally extending slot extending radially from said nut bore through the surface of said nut, said radial, longitudinally extending slot in said nut being registerable with said radial, longitudinally extending slot in said elongated body to form a continuous elongated slot along the length of said tool, said continuous elongated slot being adapted to receive the guidewire.

Abstract
A laterally attachable and detachable tool for manipulating a guidewire includes a cylindrical body that terminates in a collet. A nut is threaded to the collet and can be tightened to draw the collet arms inwardly. The body and the nut each include a lateral slot of a width to receive the guidewire. The slot in the nut is registrable with the slot in the body to form a continuous slot, receptive to the guidewire, along the length of the tool.

11. A tool for manipulating a guidewire comprising:
-
an elongated body having a bore extending axially therethrough, said elongated body having an opening laterally extending from said elongated bore through the surface of said elongated body, said laterally extending opening in said body being adapted to receive the guidewire; said elongated body including a collet portion having a plurality of spaced slots radially extending from said elongated bore through the surface of said collet portion, one of said plurality of spaced radially extending slots including said laterally extending opening extending through said collet portion and having a width larger than the width of the other of said plurality of spaced radially extending slots, a portion of said surface of said collet portion being threaded; and a nut threadably mounted to said collet portion and having a bore extending axially therethrough, said nut having a slot laterally extending from said bore through the surface of said nut, said laterally extending slot in said nut being alignable with said laterally extending opening in said elongated body to form a continuous elongated slot along the length of said tool, said continuous elongated slot being adapted to receive the guidewire.
