1. A balloon catheter comprising:
- an elongate hollow, thin wall, tube having a lumen extending therethrough from a proximal end to a distal end;
a hollow, flexible torque transmitting shaft having a first end connected to the distal end of the tube and having a flow lumen therethrough which is in communication with the lumen of the tube;
an elongate core member extending distally from a second end of the shaft; and
an inflatable balloon surrounding the core member and having a proximal end bonded to the second end of the shaft and a distal end bonded to the core member, an interior of the balloon being in communication with the flow lumen.

Abstract
A balloon catheter for use in angioplasty that includes a main shaft which is a flexible thin walled metal tube and a hollow, flexible torque transmitting shaft mounted at the distal end of the main shaft. A core member is connected to the torque transmitting shaft, and an inflatable balloon is mounted over the core and is attached to the distal end of the flexible torque transmitting shaft.

15. A balloon catheter comprising:
-
a main shaft having a first inflation lumen extending therethrough from a proximal end to a distal end; a secondary shaft having a proximal end connected to the distal end of the main shaft and having a second inflation lumen extending therethrough from the proximal end to a distal end;
the second inflation lumen being connected to the first inflation lumen, the secondary shaft having greater flexibility than and substantially similar torque transmitting characteristics to the main shaft;an elongate core member extending distally from the distal end of the secondary shaft; and an inflatable balloon surrounding the core member and having a proximal end connected to the distal end of the secondary shaft, a distal end connected to the core member, and an interior in communication with the second inflation lumen. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
