Catheters having a reusable proximal body
First Claim
1. An elongated intravascular catheter comprising:
- a generally tubular distal catheter shaft section having a proximal end, a distal end, and a single lumen extending therein to a port in the distal end, said distal shaft section having no more than one lumen and being configured for advancement through a patient'"'"'s blood vessel;
an elongated proximal catheter shaft section having a proximal end, a distal end, and a single lumen extending therein to a port in the distal end, said proximal shaft section having no more than one lumen and being releasably connected to the distal shaft section so that the lumen of the distal shaft section is in fluid communication with the lumen in the proximal shaft section; and
a balloon on the distal shaft section having an interior in fluid communication with the lumen of the distal shaft section and the lumen of the proximal shaft section.

Abstract
Catheters including a rugged, reusable proximal body and a disposable distal body attached by a releasable connection are provided. The reusable proximal body is constructed from resterilizable materials such as glass, metal alloys and engineering plastics. The disposable distal body, designed for one-time use, is made from reliable but inexpensive materials. The catheters may be dilatation catheters and may be manufactured in any configuration, including rapid exchange, balloon-on-a-wire, and over-the-wire designs with single or multiple lumens. The modular construction of the catheter and releasable connection provides for rapid and easy changes in the configuration and balloon size depending on the needs of the medical procedure.

13. A distal catheter shaft section which is configured to be releasably engaged with a proximal catheter shaft section and to be inserted within a body lumen, said distal catheter shaft section comprising;
-
an elongated, body having a proximal end, a distal end and a single lumen extending therein to a port in the distal end of the distal shaft section, said proximal end configured to releasably engage a proximal catheter shaft section; and
a balloon on the distal shaft section having an interior in fluid communication with the lumen of the distal shaft section.

14. A method for performing medical procedures using a catheter comprising the steps of:
-
providing a catheter with a generally tubular distal catheter shaft section having a proximal end, a distal end and no more than one lumen extending therein to a port in the distal end, a proximal catheter shaft section having a proximal end, a distal end and no more than one lumen extending therein, and a releasable connection sealingly connecting said distal end of said proximal catheter shaft section and said proximal end of said distal catheter shaft section in fluid communication, and a balloon on the distal shaft section having an interior in fluid communication with the lumen of the distal shaft section and the lumen of the proximal shaft section;
inserting at least a distal portion of said proximal catheter shaft section into a patient;
pulling the proximal end of the proximal shaft section to withdraw said distal catheter shaft section from said patient and disengaging said distal catheter shaft section from said proximal catheter shaft section. - View Dependent Claims (15, 16)
