AbstractA fully exchangeable low-profile single-lumen dual-balloon catheter for embolectomy, dilatation, occlusion, and infusion of treatment fluid, and having an integrated guide wire, includes a flexible small diameter guide wire provided with an distal end valving portion of comparatively enlarged diameter and a flexible elongated tubular shaft with a pair of expandable balloons spaced apart on opposite sides of a waist portion which waist portion includes an infusion section with a perforation in fluid communication with the lumen. The fluid conducting lumen is adapted to perform multiple functions in conjunction with movements of the guide wire converting the catheter to one of several modes of operation by sealing cooperation of the guide wire valving portion with seal portions of the catheter shaft.
