COAXIAL BI-DIRECTIONAL CATHETER
First Claim
1. A deflectable catheter comprisingan outer member having a proximal portion and a distal portion;
- an elongated column member extending distally from the outer member;
an inner member positioned coaxial with the outer member and attached to the column member, the inner member extending distally of the outer member and having a distal tip portion; and
a reinforcement member positioned over the column member to restrict axial movement of the column member such that when one of the inner member or outer member is moved with respect to the other, axial compression of the column member is restricted by the reinforcement member causing the distal tip portion of the inner member to deflect laterally.

Abstract
A deflectable catheter including an outer member having a proximal portion and a distal portion, an elongated column member extending distally from the outer member and an inner member positioned coaxial with the outer member and attached to the column member. The inner member extends distally of the outer member and has a distal tip portion. A reinforcement member is positioned over the column member to restrict axial movement of the column member such that when one of the inner member or outer member is moved with respect to the other, axial compression of the column member is restricted by the reinforcement member causing the distal tip portion of the inner member to deflect laterally.

- 13. A deflectable catheter comprising a proximal portion, an intermediate portion and a deflectable distal tip portion, a first movable member axially movable from a first position to a second position, wherein the distal tip portion is deflectable by an axial movement of the first member in which the distal tip portion cannot fail axially in compression so it fails laterally causing deflection of the distal tip portion in a first direction.

18. A deflectable catheter having a deflectable distal tip portion, the catheter comprising:
-
an outer catheter having a lumen, a proximal portion and a distal portion; an inner catheter positioned coaxially within the inner lumen of the outer catheter and having a distal tip portion extending distally of a distal end of the outer catheter; and a column member attached to the inner catheter, wherein axial movement of one of the outer member and inner member acts on the column member to cause the distal tip portion of the inner catheter to deflect laterally. - View Dependent Claims (19, 20)
