Apparatus and method are disclosed for facilitating balloon catheter exchange in the vascular system of a patient. The apparatus and method concern means for holding a guidewire longitudinally fixed with respect to a guiding catheter while a balloon catheter is moved over the guidewire. Specifically, the guidewire is held longitudinally fixed with respect to the guiding catheter by way of magnetic coupling. A first magnetic element constitutes a portion of the guide wire or is attached to the guide wire to move with it. A second magnetic element is located proximate the balloon catheter but is not fixed to the balloon catheter. When the guidewire is moved within the guiding catheter to a location at which the first magnetic element reaches its point of closest approach to the second magnetic element, magnetic force holds the guidewire against movement relative to the guiding catheter even while a balloon catheter is being moved over the guidewire.

A biopsy forceps device includes a handle assembly having a handle portion and a hub portion. An elongated flexible hollow body portion preferably in the form of a coiled spring guide wire extends from the hub portion to a forceps assembly. A control wire extends through a lumen in the guide wire as well as a lumen in the hub portion and is coupled at one end to the handle portion and at the other end to the forceps assembly. A flexible coupling interconnects the hub portion with the handle portion so that the hub portion may be angularly displaced with respect to the distal end of the handle portion. The flexible coupling takes the form of a ball and socket arrangement with the ball being carried by the hub portion and the socket being carried by the handle portion.

A fracture fixation system is provided for the insertion of a fixation pin into the medullary canal of a fractured metacarpal, metatarsal, or phalangeal bone for stable bone fixation. The system includes a pin and an instrument for implanting the pin. According to one embodiment of the invention, the instrument includes a main handle and a pin handle movable relative to the main handle. The main handle includes a distal end, a drill coupled to the distal end, and a longitudinal slot which receives the pin handle. The drill includes a shaft having a distal boring tip and a groove proximal the boring tip for guiding the fixation pin. The pin handle is shaped and sized to slidably move within the longitudinal slot. The pin includes a curved, distal end. The distal end rests within the groove of the drill shaft.

An intravascular catheter is described which is capable of rapid exchange without dislodging of a guidewire and without the presence of side apertures in the catheter. The catheter comprises a plurality of segments which are secured together in end-to-end relation, but which are separable into separated segments by the user while the distal catheter end is inserted in the vascular system of a patient.
