Medical guide wire doubling as a catheter
First Claim
1. (Amended) A medical guide wire serving also as a catheter to be inserted into the vasculature of a human or animal body comprising a guide wire body, and a bulge body attached to the guide wire body close to its distal tip end, the guide wire enclosing a pipe passing through its interior to be connected to the bulge body and the bulge body having one, or two or more medicinal outlets in the form of slit- or pore-like openings communicating with the pipe, whereby it is possible to produce an ablation at a specified part on the inner wall of a vessel or to dilate a stenotic lesion developed on the part by vibrating or moving the bulge body placed in contact with the lesion, as well as to allow a therapeutic agent passing through the guide wire body to flow out from the medicinal outlets of the bulge body to be applied to the lesion.

Abstract
This application is to provide a medical guide wire serving also as a catheter which requires only single insertion operation, and nevertheless by which it is possible to apply a pressure to a specified part on the internal wall of a vessel, to thereby expand the narrowed lumen, or to cut the part for removal, as well as to apply a therapeutic agent to the part.
The medical guide wire is inserted into the vasculature of a human or animal body comprising a guide wire body, and a bulge body attached to the distal tip end of the guide wire body, with the guide wire body enclosing a pipe connected to the bulge body and the bulge body including one, or two or more medicinal outlets connected to the pipe, whereby it is possible to ablate or to dilate a stenotic lesion on a specified part of the inner wall of a vessel, as well as to allow a therapeutic agent to flow out through the medicinal outlets to be applied to the lesion, by placing the bulge body close to the specified part and by vibrating or moving the bulge body in contact with the lesion.

17. (Amended) A medical guide wire serving also as a catheter to be inserted into the vasculature of a human or animal body comprising a guide wire body, and a bulge body attached to the guide wire body close to its distal tip end, the guide wire body enclosing a pipe passing through its interior to be connected to the bulge body, and the bulge body being constituted of a first and second bulge bodies with a bulge body segment placed between the first and second bulge bodies carrying one, or two or more medicinal outlets communicating with the pipe,
wherein a first potential source is connected to a first bulge body and/or a second potential source to a second bulge body; - production of an ablation at a specified part on the inner wall of a vessel or dilatation of a stenotic lesion developed on the part is achieved by vibrating or moving the bulge body placed in contact with the lesion; and
a voltage or ultrasonic vibration is applied to one of the two bulge bodies, or between the first and second bulge bodies, while a therapeutic agent is allowed to flow out from the medicinal outlets to be applied to the lesion. - View Dependent Claims (18, 19, 20, 21)
