Rapid exchange segmented catheter
First Claim
1. An intravascular catheter which comprises proximal and distal ends, said catheter comprising a plurality of segments having connectors which are secured together in end-to-end relation, but which connectors are separable by the user to form separated segments while the distal catheter end is in an inserted position in the vascular system of a patient, said catheter further defining a distal catheter segment connected to an inflation lumen, and said inflation lumen comprises a separate tube that is unconnected to said segments other than the distal catheter segment.

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.

9. An intravascular catheter which comprises proximal and distal ends;
- a balloon connected to an inflation lumen, said balloon being carried adjacent said distal end, said catheter comprising a plurality of segments having connectors which are secured together in end-to-end relation, but which are both separable into separated segments by the user, and said connectors also being connectable together by the user from a separate segment relation to form said catheter, while the distal catheter end is inserted into the vascular system of a patient.

15. The method of removing an intravascular catheter from the vascular system of a patient, which catheter resides in the vascular system of said patient surrounding a guidewire, which comprises:
- grasping said catheter and grasping said guidewire;
partially withdrawing said catheter out of the vascular system of the patient through the skin of the patient while restraining the guidewire from retracting movement;
removing a proximally mounted section of said catheter from the remainder of said catheter, and separately sliding said catheter section off of the guidewire while substantially continuously grasping the guidewire to prevent retracting movement thereof. - View Dependent Claims (16, 17, 18, 19)
