ABSTRACT:
A remote controlled catheter with micro-balloon, having a head constituted by a cylindrical coil spring (2) having separated coils covered by a micro-balloon (10) and mounted coaxially at the end of a tube (1). The spring can be bent at will in order to facilitate its introduction along arteries. The user pulls on the rear of a flexible pulling member (5) the forward end of which is fastened to the upper part of the head eccentrically of the axis of the head, this element (5) passing within the tube (1). To inflate the balloon (10), fluid is introduced through a channel (11), through the tube (1), the base of the balloon (10) being fixed to the tube (1) in a sealed manner. To inject a contrast liquid within the arterial channel, this liquid is introduced by a channel (12) communicating with the space between the tube (1) and the covering (9) and is expelled through two openings (13 and 14), this latter operation being possible thanks to the fact that one of the ends of the covering (9) is sealed to the frame member (6), whereas the other end is also sealed but on the tube (1).
