Abstract
Abstract An intravascular catheter is described which is capable of rapid exchange without dislodging of a guidewire and without the presence of side apertures in the catheter. The catheter comprises a plurality of segments which are secured together in end-to-end relation, but which are separable into separated segments by the user while the distal catheter end is inserted in the vascular system of a patient.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
75 words
A method for exchanging a catheter in the vascular system of a patient, which comprises the steps of: introducing a guidewire into said vascular system; introducing a catheter into said vascular system over said guidewire, said catheter having at least a distal section and a connected proximal section; withdrawing said catheter from said vascular system by first removing only said proximal section while restraining said guidewire; thereafter removing said distal section while restraining said guidewire.
Claim 2
Independent Claim
75 words
A method for exchanging a catheter in the vascular system of a patient, which comprises the steps of: introducing a guidewire into said vascular system; introducing a catheter into said vascular system over said guidewire, said catheter having at least a distal section and a connected proximal section; withdrawing said catheter from said vascular system by first removing only said proximal section while restraining said guidewire; thereafter removing said distal section while restraining said guidewire.
Claim 3
Dependent Claim
41 words
A method as defined by claim 1, in which the step of introducing includes first introducing only said distal section over the guidewire and thereafter introducing said proximal section over the guidewire and connecting said proximal section to said distal section.
Claim 4
Dependent Claim
42 words
A method as defined in claim 1, in which said proximal section comprises a plurality of connected sections and the step of removing said proximal section comprises the step of removing said plurality of sections, one by one while restraining said guidewire.
Claim 5
Dependent Claim
33 words
A method as defined by claim 1, in which said segments connect together with a screw threaded connection and said proximal section removing step comprises unscrewing said proximal section from said distal section.
Claim 6
Dependent Claim
32 words
A method as defined in claim 1, in which said segments connect together with a snap-fit connection and said proximal section removing step comprises unsnapping said proximal section from said distal section.
Claim 7
Dependent Claim
36 words
A method as defined by claim 1, in which said segments connect together with a twist locking slot-type connection and said proximal section removing step comprises twisting and unlocking said proximal section from said distal section.
Claim 8
Dependent Claim
32 words
A method as defined by claim 1, in which said segments connect together with a magnetic connection and said proximal section removing step comprises demagnetic-coupling said proximal section from said distal section.
Claim 9
Dependent Claim
84 words
A catheter for introduction into and withdrawal from the vascular system of a patient over a guidewire in said vascular system, which comprises: said catheter having a distal section and a proximal section; said distal section and said proximal section being alternatively connectable and separable; said catheter being adapted for introduction into said vascular system over said guidewire and for withdrawal from said vascular system by removing said proximal section while restraining said guidewire and thereafter removing said distal section while restraining said guidewire.
Claim 10
Dependent Claim
84 words
A catheter for introduction into and withdrawal from the vascular system of a patient over a guidewire in said vascular system, which comprises: said catheter having a distal section and a proximal section; said distal section and said proximal section being alternatively connectable and separable; said catheter being adapted for introduction into said vascular system over said guidewire and for withdrawal from said vascular system by removing said proximal section while restraining said guidewire and thereafter removing said distal section while restraining said guidewire.
Claim 11
Dependent Claim
20 words
A catheter as defined by claim 8, said proximal section comprising a plurality of sections that are connectable and separable.
Claim 12
Dependent Claim
16 words
A catheter as defined by claim 8, said sections being connectable together with a screw-threaded connection.
Claim 13
Dependent Claim
18 words
A catheter as defined by claim 8, in which said sections are connected together with a snap-fit connection.
Claim 14
Dependent Claim
19 words
A catheter as defined by claim 8, in which said sections are connected together with a twist-locking slot-type connection.
Claim 15
Dependent Claim
17 words
A catheter as defined by claim 8, in which said sections connect together with a magnetic connection.
Claim 16
Dependent Claim
22 words
A catheter as defined by claim 8, said distal section carrying an inflatable balloon and defining a lumen for inflating said balloon.
