Abstract
A wire gripping handle for attaching to and detaching from wires defines a first tubular member, and a second tubular member which receives the first tubular member in generally coaxial relation. Both tubular members define a longitudinal slot so that, when the slots are aligned, a wire may be placed into the bores of the joined tubular members in lateral fashion. Then, upon relative rotation of the tubular members, a portion of one of them may be radially collapsed into gripping relation with the wire.
Claims12
A wire-gripping handle for attaching to and detaching from catheter guidewires and the like, which handle comprises:
- a first tubular member having a first bore, and a first side wall which defines a longitudinal slot extending across at least one end of said first tubular member, to permit a wire to be laterally inserted through said slot to occupy at least part of said first bore and to extend from said first bore longitudinally out of said one end;
- a second tubular member having a second bore which receives a portion of said first tubular member including said one end, whereby a wire extending out of said one end also can extend from said second bore out of the end of said second tubular member which faces away from said first tubular member;
- said second tubular member having a second side wall that defines a longitudinal, wire-passing slot extending between its ends;
- threaded means to permit said first and second tubular members to be rotatably advanceable and retractable relative to each other, the first tubular member and second bore being proportioned to radially collapse a portion of said first tubular member adjacent said one end as the first and second members are rotatably advanced relative to each other, to grip a wire carried therein.
A wire-gripping handle.. for attaching to and detaching from catheter guidewires and the like, which handle comprises:
- a first tubular member having a first bore and a first side wall which defines a longitudinal slot extending along the entire length of and through both ends of said first tubular member, to permit a wire to be laterally inserted through said slot to occupy said first bore and to extend from said first bore longitudinally out of at least one end of said first tubular member;
- a second tubular member having a second bore which receives a portion of said first tubular member including said one end, whereby a wire extending out of said one end can also extend from said second bore out of the end of said second tubular member which faces away from said first tubular member, said second tubular member having a second side wall that defines a longitudinal, wire-passing slot extending between its ends;
- threaded means to permit said first and second tubular members to be rotatably advanceable and retractable relative to each other, the first tubular member and second bore being proportioned to radially collapse a portion of said first tubular member adjacent said one end as the first and second members are rotatably advanced relative to each other, to grip a wire carried therein, the one end of said first tubular member defining a plurality of radial slots to facilitate the radial collapse thereof.
