Abstract
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.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
103 words
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.
Claim 2
Dependent Claim
103 words
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.
Claim 3
Dependent Claim
94 words
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 proximal to the therapy means, wherein the loop is a peelable sheath; wherein the catheter is reinforced with a stiffening means mounted to the body; and wherein the stiffening means is a stylet.
Claim 4
Dependent Claim
94 words
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 proximal to the therapy means, wherein the loop is a peelable sheath; wherein the catheter is reinforced with a stiffening means mounted to the body; and wherein the stiffening means is a stylet.
Claim 5
Dependent Claim
90 words
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 with an occluded distal end fixedly attached to the body and mounted proximal to the therapy means; a second wire guiding means being a peelable sheath and mounted proximal to the first wire guiding means.
Claim 6
Dependent Claim
90 words
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 with an occluded distal end fixedly attached to the body and mounted proximal to the therapy means; a second wire guiding means being a peelable sheath and mounted proximal to the first wire guiding means.
Claim 7
Independent Claim
62 words
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 distal to the balloon; inserting a guidewire through the first loop and the second loop; wrapping the balloon around the guidewire; and inserting the catheter and guidewire in the human body.
Claim 8
Independent Claim
62 words
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 distal to the balloon; inserting a guidewire through the first loop and the second loop; wrapping the balloon around the guidewire; and inserting the catheter and guidewire in the human body.
Claim 9
Dependent Claim
27 words
The method of claim 4, further comprising: withdrawing the guidewire in the proximal direction so that the guidewire is proximal to the balloon; and inflating the balloon.
Claim 10
Dependent Claim
17 words
The method of claim 5, further comprising: deflating the balloon; and withdrawing the catheter over the guidewire.
Claim 11
Dependent Claim
39 words
The method of claim 6 further comprising; positioning the guidewire over the stenosis, inserting a different catheter with an angioplasty balloon over the guidewire into the body, inflating the balloon, deflating the balloon, withdrawing the catheter over the guidewire.
Claim 12
Independent Claim
106 words
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.
Claim 13
Independent Claim
106 words
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.
Claim 14
Dependent Claim
21 words
The method of claim 8 wherein the step of removing the guidewire from the first guidewire loop includes withdrawing the guidewire.
Claim 15
Dependent Claim
21 words
