1. A floating wind turbine, comprising:

a barge capable of floating in a body of water;

a plurality of airfoils extending from the baige, the barge and the airfoils forming a rigid structure capable of 15 rotating together as a unit;

a generator housing located adjacent to the barge, the generator housing containing an electric generator secured therein;

anti-rotation means mounted on the generator housing to 20

limit rotation of the generator housing in the water;

a rigid shaft connected to a rotational shaft of the generator; and,

mechanical connecting means to connect the barge and airfoil unit to the rigid shaft such that rotation of the 25 barge and airfoil unit produces rotation of the generator shaft and therefore electric power.

Alternatively, tubing 45 can connect to a suction apparatus (not shown) to aspirate particles dislodged by the atherectomy bit 20 and aspirated through lumen 15 between the outer wall of the catheter 16 and inner wall of sheath 14 . Catheter 16 extends within housing 12 and through the outer sheath 14 , terminating distal of the distal end 21 of the outer sheath 14 . Rotational shaft 18 extends though the catheter 16 and terminates distal of the distal end 23 of the catheter 16 . The atherectomy bit 20 is exposed in both the retracted and extended positions of catheter 16 . This can be appreciated by comparing FIGS. 3 and 4.
