Catheter with biased shaft
First Claim
1. A balloon catheter, comprisinga) an elongated shaft having a proximal end, a distal end, an inflation lumen, and at least a section with a major transverse dimension and a minor transverse dimension, such that the shaft preferentially bends in a direction of the minor transverse dimension;
- b) a balloon on a distal shaft section having an interior in fluid communication with the inflation lumen; and
c) a prosthesis having a first end, and a truncated second end, the prosthesis being mounted on the balloon such that the truncated second end tapers in the direction of the minor transverse dimension of the shaft.

Abstract
A catheter including an elongated shaft having a proximal end, a distal end, at least one lumen, and at least a section with a major transverse dimension and a minor transverse dimension, such that the shaft preferentially bends in the direction of the minor transverse dimension. In one embodiment, the catheter is a balloon catheter having a balloon on a distal shaft section, and having a prosthesis mounted on the balloon. In a presently preferred embodiment the prosthesis has a first end and a truncated second end, and is mounted on the balloon such that the truncated second end tapers in the direction of the minor transverse dimension of the shaft. In another embodiment, the catheter has an operative member, such as a drug delivery balloon or an atherectomy member or a radiation, sonic, or light emitter, disposed on or within a distal shaft section, the operative member having an operative surface facing in a direction substantially aligned with the minor transverse dimension of the shaft. The shaft preferentially bends in the direction of the minor transverse dimension, to thereby provide improved ability to position a prosthesis or the operative surface of a catheter operative member in a desired orientation within a patient'"'"'s body lumen.

18. A method of performing a medical procedure, comprising
a) positioning within a body lumen a balloon catheter, comprising i) an elongated shaft having a proximal end, a distal end, an inflation lumen, and at least a section with a major transverse dimension and a minor transverse dimension, such that the shaft preferentially bends in a direction of the minor transverse dimension; -
ii) a balloon on a distal shaft section having an interior in fluid communication with the inflation lumen; and
