Medical device
First Claim
1. A medical device comprising:
- an elongated inner tubular member including a proximal portion and a distal portion and defining an outer surface and a lumen;
an elongated tubular reinforcing member having an inner surface, the reinforcing member being disposed about the proximal portion of the inner tubular member such that the distal portion of the inner tubular member is free of the reinforcing member, and such that at least a portion of the outer surface of the inner tubular member along the proximal portion faces and is spaced apart from the inner surface of the reinforcing member;
wherein the reinforcing member comprises a wall defining a plurality of apertures; and
wherein the spacing between the outer surface of the inner tubular member and the inner surface of the reinforcing member forms a space that is unfilled by any other structure of the device.

Abstract
An medical device include a shaft having an elongated inner tubular member and an elongated tubular reinforcing member disposed over a portion of the inner tubular member. In some embodiments, the reinforcing member is disposed about a proximal portion of the inner tubular member such that a distal portion of the inner tubular member is free of the reinforcing member. In some embodiments, the at least a portion of an outer surface of the inner tubular member is spaced from an inner surface of the reinforcing member. In some embodiments, the shaft can include a tip structure disposed on the distal portion of the inner tubular member. In some such embodiments, reinforcing member has a distal end, and the tip structure is disposed on the distal portion of the inner tubular member adjacent the distal end of the reinforcing member. Additionally, in some embodiments, the reinforcing member can include a plurality of apertures defined therein, for example, to enhance the flexibility or other such characteristics of all of portions of the reinforcing member.
