1. A catheter assembly comprising:
- an outer catheter member extending from a first distal end to a first proximal end, where the first distal end is flexible;
the outer catheter member having a first lumen therein, the first lumen extending from the first distal end to the first proximal end;
an inner catheter member movably disposed within the first lumen of the outer catheter member;
the inner catheter member extending from a second distal end to a second proximal end; and
the outer catheter is more flexible than the inner catheter member.

Abstract
A catheter assembly includes an outer catheter member having a distal flexible end. An inner catheter member is movably disposed within the outer catheter member. Optionally, a handle assembly is coupled with the outer catheter member and the inner catheter member, where the handle assembly is adapted to slide the inner catheter member relative to the outer catheter member.
