Medical device
First Claim
1. A medical device comprising:
- an elongated inner member having a lumen formed therein, an outer surface, and a distal end; and
an elongated tubular reinforcing member having a distal end, an inner surface, an outer surface and a wall therebetween, the wall defining a plurality of apertures;
wherein the distal end of the inner member is disposed distally of the distal end of the reinforcing member;
wherein the tubular reinforcing member is disposed about and spaced away from at least a portion of the inner member such that a space is defined between the outer surface of the inner member and the inner surface of the tubular reinforcing member;
wherein the space is substantially free of any other structures of the device; and
a coil disposed about a distal portion of the inner member, wherein the coil is disposed distal of the distal end of the tubular reinforcing member.

Abstract
A medical device including a shaft having an elongated inner member and an elongated tubular reinforcing member disposed over at least a portion of the inner member. In some embodiments, at least a portion of the outer surface of the inner member is spaced from the inner surface of the reinforcing member, defining a space substantially free of any other structures of the device. In some embodiments, the shaft can include a tip structure disposed on a distal portion of the inner member. In some such embodiments, the reinforcing member has a distal end, and the tip structure is disposed on the distal portion of the inner 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 or portions of the reinforcing member.
