First Claim
1. A medical catheter comprising:
- an elongated shaft defining a lumen extending along a longitudinal axis, the shaft including a proximal portion having a proximal end and a distal portion having a distal end;
the proximal portion of the shaft including a flared section disposed adjacent the proximal end, the flared section being flared outwardly at an angle relative to the longitudinal axis of the shaft.

Abstract
A medical device including an alternative shaft configuration, structure, assembly, and method for making. For example, some shaft configurations relate to the use of an inner and an outer tubular member. Additionally, some alternative distal tip structures, assemblies, and methods for elongated medical devices are disclosed. Additionally, some alternative structures, assemblies, and methods for proximal shaft constructions and for connecting manifolds to medical devices are disclosed. For example, the shaft of a medical device may be provided with a flared proximal portion that is adapted to mate with structure on a manifold assembly. Additionally, the manifold assembly may include structures, for example, protrusions and/or recessed portions, which are adapted to mate with the flared section of the shaft.
