    摘要: A medical device allows movement control of a distal end portion of the medical device and is adapted for one-handed operation. The medical device is capable of omni-directional control of the distal end portion of the device. The device has an elongated member including a deflectable portion at a distal end portion of the elongated member. The device also has a control portion disposed on the elongated member. This control portion can be a handle for one-handed use by an operator of the medical device. The control portion comprises an elastic element and a flexible element. Angular movement of a first portion of the control portion with respect to a second portion of the control portion results in amplification of that angular movement in the deflectable portion of the device.

    摘要: A guidewire and catheter are adapted for advancement through tight or tortuous vascular anatomy by providing detachably connectible threaded elements at the distal ends of each of the catheter and guidewire. When threaded together, the combined catheter and guidewire provide enhanced column strength to facilitate pushing the two together through the vascular anatomy. Alternately, the guidewire may be rotated in a manner that draws the catheter in screw-like fashion in a distal direction.
