Catheter with disruptable guidewire channel
First Claim
1. A balloon and catheter assembly comprising an enlargeable balloon, having a length, mounted on a catheter shaft;
- a sleeve attached to the balloon forming a guidewire channel along at least a portion of the balloon;
wherein the sleeve is disruptable to cause a guidewire placed within the sleeve to free from the balloon when the sleeve is disrupted.

Abstract
The present invention is a catheter device that includes a disruptable guidewire channel. The guidewire channel is configured to provide necessary trackability of the catheter along the guidewire during introduction of the catheter to a treatment site. Once treatment is completed, the guidewire channel can then be disrupted so as to free the guidewire from the catheter in situ. The apparatus of the present invention provides distinct advantages over existing over-the-wire and rapid exchange catheter introduction methods, including the ability to achieve much faster treatment implement exchanges, the ability to rapidly deliver multiple treatment implements in series, and the ability to maintain multiple treatment implements simultaneously at a treatment site using a single guidewire.

25. A medical device comprising
a balloon configured for insertion within a patient'"'"'s body directed along a guidewire; -
a guidewire channel exterior to the balloon;
the guidewire channel formed from a material that maintains the guidewire close to the balloon during insertion and alters upon inflation of the balloon to separate the guidewire from the balloon upon subsequent deflation of the balloon. - View Dependent Claims (26, 27, 28, 29)
