  • Patent number: 5423331
    Abstract: A steering device (2) for directing passage of a remote portion of an elongated member (4) such as a catheter guidewire, fiber optic bundle or the like, preferably a guidewire for use in percutaneous transluminal angioplasty. The steering device (2) includes a releasable gripping mechanism for releasably gripping a proximate portion of the elongated member (4). The gripping mechanism includes opposing gripping surfaces (30a) and (30b) which cooperate to grip the proximate portion of the elongated member (4) therebetween when said gripping mechanism is manipulated by the exertion of force so that the device (2) is in a gripping position and the device (2) grips the elongated member (4). The elongated member (4) can be inserted laterally into the device (2). A preferred embodiment (2") includes a living hinge (68) which biases the preferred steering device (2") to a partially open position wherein the wire (4") can be laterally inserted or removed from the device (2").

  • Patent number: 4957117
    Abstract: A steering device for directing passage of a remote portion of a length of wire, preferably a guide wire for use in percutaneous transluminal angioplasty. The steering device includes a releasable gripping mechanism for releasably gripping a proximate portion of the length of wire. The gripping mechanism includes and opposing gripping surfaces which cooperate to grip the proximate portion of the length of wire therebetween when said gripping mechanism is manipulated by the exertion of a translational force so that it is in a gripping position and the device grips the length of wire.
