1. A medical catheter comprising:
- an elongate body having a proximal end and a distal end;
a therapy means mounted on the body generally adjacent to the distal end for providing medical treatment;
a first wire guiding means, mounted external to the body, for mounting over a guidewire, the first wire guiding means being a loop fixedly attached to the body and mounted proximal to the therapy means; and
a second wire guiding means mounted external to the body for mounting over a guidewire, the second wire guiding means being a loop fixedly attached to the body and mounted distal to the therapy means.

Abstract
A balloon catheter is disclosed having a catheter body and one or more loops external to the body and spaced from the balloon for insertion of a guidewire. A peelable sheath with a guidewiare lumen can instead be mounted exterior to the catheter body for holding the guidewire. The catheter body may optionally be reinforced with a stylet.

8. A method of inserting a catheter on a guidewire comprising:
-
providing a catheter with an angioplasty balloon having a first guidewire loop proximal to the balloon and a second guidewire loop proximal to the first guidewire loop; inserting the guidewire through the first and second guidewire loops; inserting the catheter and guidewire in a human body; removing the guidewire from the first guidewire loop; placing the guidewire external to the outside surface of the first guidewire loop; and allowing the catheter to be withdrawn over the second guidewire loop while maintaining access to a vessel being treated by keeping the guidewire in place in the vessel. - View Dependent Claims (9, 10, 11, 12)
