Catheter systems and associated methods utilizing removable inner catheter or catheters

Abstract

A catheter system for use in a body of a patient is disclosed. The catheter system includes a guide catheter having a distal guide orifice, a proximal guide orifice, and a guide lumen extending therebetween. The catheter system further includes an original catheter positionable within the guide lumen of the guide catheter, wherein the original catheter has an original lumen and an original distal orifice. In addition, the catheter system includes a replacement catheter positionable within the guide lumen of the guide catheter, wherein the replacement catheter has a replacement lumen and a replacement distal orifice. The catheter system also includes a closure member securable to the guide catheter so as to cover the proximal guide orifice. The original distal orifice is positioned on an original distal segment of the original catheter which extends out of the distal guide orifice of the guide catheter when the original catheter is positioned within the guide lumen of the guide catheter. The replacement distal orifice is positioned on a replacement distal segment of the replacement catheter which extends out of the distal guide orifice of the guide catheter when the replacement catheter is positioned within the guide lumen of the guide catheter. A method of performing a medical procedure with a catheter system is also disclosed.
