BALLOON CATHETER FOR TREATMENT OF A VESSEL AT A BIFURCATION

摘要

A balloon catheter having a balloon with a shape for treating a vessel at a bifurcation, includes an oblique proximal end of the balloon, and a catheter shaft which is at least partially eccentric to a central axis of the balloon. Markers used for longitudinal and rotational alignment are included on the catheter shaft. A torque transmission element may be used for transmitting torque from the stiff proximal segment of the catheter to the distal flexible balloon segment of the catheter.

1. A balloon catheter, the balloon catheter comprising:
a shaft having a shaft distal end and a shaft proximal end along a longitudinal axis; and a balloon positioned on said shaft, said balloon having a balloon distal end and a balloon proximal end along said longitudinal axis, wherein said balloon proximal end has a long wall portion and a short wall portion opposite said long wall portion wherein said long wall portion extends past said short wall portion in a proximal direction along said longitudinal axis, such that said balloon proximal end is substantially at an oblique angle to a plane which is perpendicular to said longitudinal axis when said balloon is in an expanded state.
