Abstract
Abstract A balloon dilatation catheter defines an inflation lumen communicating with its balloon, and a guidewire lumen extending along the catheter. An aperture portion is defined in the catheter shaft between the guidewire lumen and the catheter exterior, the aperture portion being covered by a frangible wall that is typically thinner than the rest of the tubular catheter shaft wall. The catheter may be used in either the conventional over-the-wire technique or the "rapid exchange" technique of balloon angioplasty.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
111 words
A method of inserting a balloon dilatation catheter into the vascular system of a patient along a guidewire previously emplaced in the patient, which comprises: passing the proximal end of the guidewire into the distal end of a guidewire lumen of the catheter, and advancing the catheter distally along the guidewire; puncturing a side opening in said catheter through a catheter wall portion that is thinner than most of the catheter wall, said punctured side opening extending between the guidewire lumen and the exterior of the catheter; and causing the guidewire proximal end to pass through said side opening from the guidewire lumen to the exterior as the catheter is advanced.
Claim 2
Independent Claim
111 words
A method of inserting a balloon dilatation catheter into the vascular system of a patient along a guidewire previously emplaced in the patient, which comprises: passing the proximal end of the guidewire into the distal end of a guidewire lumen of the catheter, and advancing the catheter distally along the guidewire; puncturing a side opening in said catheter through a catheter wall portion that is thinner than most of the catheter wall, said punctured side opening extending between the guidewire lumen and the exterior of the catheter; and causing the guidewire proximal end to pass through said side opening from the guidewire lumen to the exterior as the catheter is advanced.
Claim 3
Dependent Claim
37 words
The method of claim 1 in which a portion of said guidewire passes through said side opening as the catheter is advanced, and said portion extends proximally from said side opening and generally parallel to said catheter.
Claim 4
Dependent Claim
23 words
The method of claim 2 in which said side opening is punctured at a position spaced proximally of the balloon of said catheter.
Claim 5
Dependent Claim
25 words
The method of claim 3 in which a support mandrel is placed in a proximal portion of said guidewire lumen spaced from said side opening.
Claim 6
Dependent Claim
19 words
The method of claim 1 in which said side opening is punctured by the proximal end of said guidewire.
Claim 7
Dependent Claim
71 words
The method of claim 1 in which a portion of said guidewire passes through said side opening as the catheter is advanced, and said portion extends proximally from said side opening and generally parallel to said catheter while a support mandrel is positioned in a proximal portion of said guidewire lumen spaced from said side opening, said opening being punctured at a position spaced proximally of a balloon of said catheter.
Claim 8
Dependent Claim
20 words
The method of claim 6 including the step of puncturing said side opening with the proximal end of said guidewire.
Claim 9
Independent Claim
156 words
A method of inserting a balloon dilatation catheter into the vascular system of a patient along a guidewire previously emplaced in the patient, which comprises: passing the proximal end of the guidewire into the distal end of a guidewire lumen of the catheter, and advancing the catheter distally along the guidewire; puncturing a side opening in said catheter between the guidewire lumen and the exterior of the catheter; and causing the guidewire proximal end to pass through said side opening from the guidewire lumen to the exterior as the catheter is advanced, in which a portion of said guidewire which passes through said side opening as the catheter is advanced extends proximally from said side opening and generally parallel to said catheter while a support mandrel is positioned in a proximal portion of said guidewire lumen spaced from said side opening, said opening being punctured at a position spaced proximally of a balloon of said catheter.
Claim 10
Independent Claim
156 words
A method of inserting a balloon dilatation catheter into the vascular system of a patient along a guidewire previously emplaced in the patient, which comprises: passing the proximal end of the guidewire into the distal end of a guidewire lumen of the catheter, and advancing the catheter distally along the guidewire; puncturing a side opening in said catheter between the guidewire lumen and the exterior of the catheter; and causing the guidewire proximal end to pass through said side opening from the guidewire lumen to the exterior as the catheter is advanced, in which a portion of said guidewire which passes through said side opening as the catheter is advanced extends proximally from said side opening and generally parallel to said catheter while a support mandrel is positioned in a proximal portion of said guidewire lumen spaced from said side opening, said opening being punctured at a position spaced proximally of a balloon of said catheter.
Claim 11
Dependent Claim
20 words
The method of claim 8 including the step of puncturing said side opening with a proximal end of said guidewire.
Claim 12
Dependent Claim
41 words
The method of claim 3 in which said support mandrel has a tapered distal tip, said support mandrel distal tip being positioned to urge the guidewire proximal end out of said side opening as the catheter is advanced over the guidewire.
Claim 13
Independent Claim
99 words
The method of inserting a balloon dilation catheter into the vascular system of a patient along a guidewire previously emplaced in the patient, which comprises: passing the proximal end of the guidewire into the distal end of a guidewire lumen of the catheter, and advancing the catheter distally along the guidewire; puncturing a side opening in said catheter between the guidewire lumen and the exterior of the catheter, using the proximal end of said catheter; and causing the guidewire proximal end to pass through said side opening from the guidewire lumen to the exterior as the catheter is advanced.
Claim 14
Independent Claim
99 words
The method of inserting a balloon dilation catheter into the vascular system of a patient along a guidewire previously emplaced in the patient, which comprises: passing the proximal end of the guidewire into the distal end of a guidewire lumen of the catheter, and advancing the catheter distally along the guidewire; puncturing a side opening in said catheter between the guidewire lumen and the exterior of the catheter, using the proximal end of said catheter; and causing the guidewire proximal end to pass through said side opening from the guidewire lumen to the exterior as the catheter is advanced.
Claim 15
Dependent Claim
23 words
The method of claim 11 in which said side opening is punctured at a position spaced proximally of the balloon of said catheter.
Claim 16
Dependent Claim
38 words
The method of claim 12 in which a support mandrel is positioned in a proximal portion of said guidewire lumen spaced from said side opening as said side opening is punctured by the proximal end of said guidewire.
Claim 17
Dependent Claim
41 words
The method of claim 13 in which said support mandrel has a tapered distal tip, said support mandrel distal tip being positioned to urge the guidewire proximal end out of said side opening as the catheter is advanced over the guidewire.
Claim 18
Dependent Claim
25 words
The method of claim 1 in which a support mandrel is placed in a proximal portion of said guidewire lumen spaced from said side opening.
Claim 19
Dependent Claim
41 words
The method of claim 1 in which said support mandrel has a tapered distal tip, said support mandrel distal tip being positioned to urge the guidewire proximal end out of said side opening as the catheter is advanced over the guidewire.
