Intravascular catheter with sleeve and method for use thereof
First Claim
1. A method of performing an intravascular procedure with an guide wire and intravascular catheter having an elongate shaft, an implement located at a distal portion thereof, and a close-fitting sleeve located around the shaft and movable therealong, and further in which the intravascular catheter has a lumen shorter than a length of the catheter and having a proximal opening located at the distal portion of the elongate shaft communicating with the shorter lumen, and further in which said sleeve is located around the elongate shaft proximally of the proximal opening, the method comprising the steps of:
- advancing the guide wire intravascularly;
positioning the intravascular catheter over the guide wire in an introducer device having a hemostatic valve located at a proximal end thereof;
positioning the close fitting sleeve at the hemostatic valve;
positioning a proximal portion of the guide wire between the sleeve and the hemostatic valve;
tightening the hemostatic valve on the sleeve to form a seal between the sleeve, the guide wire and the hemostatic valve; and
advancing the intravascular catheter along the guide wire.

Abstract
An improved intravascular catheter, such as a balloon catheter, and a method for use thereof. The catheter includes an elongate shaft and the improvement includes a close fitting sleeve located around the shaft and movable therealong. The intravascular catheter is adapted to be used with an introducer device, such as a guide catheter, having a hemostatic valve located at a proximal end thereof. The close fitting sleeve is adapted to be positioned at the hemostatic valve so that the hemostatic valve can be sealed upon the sleeve allowing the intravascular catheter shaft to be readily advanced in relation to the hemostatic valve and introducer device while limiting bleeding between the sleeve and the shaft of the intravascular catheter.
