Claim 12

The device of claim 8 wherein said flush tube extends through and is fixed to said ratchet member of said ratchet means and comprise part of said moving means.

Claim 13

The device of claim 8 wherein said cylinder has a hole in the wall thereof, said ratchet means includes a ratchet pin resiliently mounted through said hole in said cylinder, said ratchet member having a saws tooth ratchet formation thereon, and said ratchet pin includes a spring biased tooth which is adapted to engage in said saw tooth ratchet formation on said ratchet member.

Claim 14

The device of claim 8 including indicia on said cylinder for indicating the extent of lateral expansion of said tubular mesh by reason of the position of one of said side rings relative to said indicia.

Claim 15

A mesh balloon catheter device comprising: a catheter having a distal end and a proximal end; a tube of woven interlaced filaments forming a tubular mesh and having a proximal end connected to the distal end of said catheter and a distal end; a flush tube extending through said catheter and said tubular mesh and fixed to the distal end of said tubular mesh; a fitting coupled to the proximal end of said catheter, said fitting including a tubular outlet that is coupled within said fitting to said flush tube; a drainage tubing extending proximally from said fitting and coupled within said fitting to said catheter for draining fluid from the area of the tubular wire; a control wire within said catheter connected to the distal end of said tubular mesh, said catheter and said fitting and out of an outlet tube of said fitting to a proximal end of said control wire; and said control wire being movable rearwardly to expand said tubular mesh into a mesh balloon.
