Claim:
A bifurcated balloon for in vivo use, comprising: i) a proximal hollow tubular element; ii) two bifurcating hollow tubular elements extending distally from a distal end of said proximal hollow tubular element, said two elements comprising: a) a first distal tubular element guidable into a first distal main branch of a vessel bifurcation; and b) a second distal tubular element having a proximal end and a distal end and being guidable into a second, side, branch of said vessel bifurcation; iii) a longitudinal central chamber extending from a distal end of said first distal tubular element into said proximal hollow tubular element, said second distal tubular element having an extension member extending from the distal end of said second distal tubular element, said extension member comprising a first guidewire channel, said first guidewire channel comprising a distal tip and a proximal tip and a distal end opening at said distal tip and a side opening at said proximal tip, said side opening at said proximal tip being adjacent to a distal end of said second distal tubular element; and iv) a second substantially longitudinal guidewire channel passing through said proximal hollow tubular element and said first distal tubular element, said second guidewire channel having two ends of which a first end passes through a proximal portion of said longitudinal chamber, and said second end of said second substantially longitudinal guidewire channel passes through said first distal tubular element, said second guidewire channel having an opening at a distal end of said first distal tubular element and a further opening at a proximal end of said proximal tubular element.
