Medical device
First Claim
1. A medical device, comprising:
- an elongate shaft having a distal end;
wherein the shaft has a plurality of slots formed therein;
a liner disposed within the shaft, the liner having a distal region disposed distally of the distal end of the shaft;
a tip member coupled to the distal region of the liner;
a hub coupled to the shaft and to the liner;
wherein the hub is coupled to the shaft at a first attachment region; and
wherein the hub is coupled to the liner at a second attachment region radially spaced from the first attachment region so that the shaft and the liner are radially spaced adjacent to the hub;
wherein the first attachment region and the second attachment region are both disposed distal to any structure of the hub that is designed to be connectable to another medical device.

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.

17. A medical device, comprising:
-
an elongate shaft having a proximal region and a distal slotted region; a liner disposed within the shaft; wherein the liner has a distal section extending distally of the distal slotted region and a proximal section extending proximally of the distal slotted region; a tip member coupled to the distal section of the liner; a hub coupled to the shaft and to the liner; wherein the hub is coupled to the shaft at a first attachment region at a distal end of the hub; and wherein the hub is coupled to the liner at a second attachment region at the distal end of the hub radially spaced from the first attachment region so that a gap is defined between the shaft and the liner. - View Dependent Claims (18, 19, 20)
