Medical device
First Claim
1. A medical device, comprising:
- a hub designed to be attachable to another medical device;
an elongate shaft coupled to the hub at a first attachment region, the elongate shaft having a plurality of slits formed within the elongate shaft;
a tubular liner disposed within the shaft, disposed along an inner surface of the shaft, and extending distally from a distal end of the shaft, the liner coupled to the hub at a second attachment region that is radially spaced from the first attachment region; and
a tip member coupled to a distal region of the liner that extends distally from the distal end of the shaft;
wherein the hub is configured such that any connection of the hub to another medical device is proximal of the first attachment region and the second attachment region.

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.
