DUAL RAPID EXCHANGE CATHETERS, SYSTEMS, AND METHODS

摘要

In one instance, a catheter for replacing or adding a guide wire into a patient is provided. The catheter includes a first rapid exchange lumen, a second rapid exchange lumen, and a releasable wire-securing device. A second guide wire is placed in the second rapid exchange lumen and secured into position. The catheter is then advanced along the first guide wire until in position, and then the second guide wire is released from the wire-securing device and advanced into the desired position. The catheter is then removed. Other catheters and methods are also disclosed.

主权项

1. A catheter for introducing a second guide wire into a patient, the catheter comprising:
a longitudinal catheter body having a distal end with a catheter tip and a proximal end, wherein the longitudinal catheter body has a first portion and a second portion that is proximal to the first portion; a first rapid exchange lumen formed in the first portion of the longitudinal catheter body, the first rapid exchange lumen having a first port proximate the catheter tip and a second port on a medial portion of the longitudinal catheter body; a second rapid exchange lumen formed in the first portion of the longitudinal catheter body, the second rapid exchange lumen having a first port proximate the distal end of the longitudinal catheter body that is proximal to the first port of the first rapid exchange lumen, and wherein the second rapid exchange lumen has a second port on a medial portion of the longitudinal catheter body; and a releaseable wire-securing device coupled to a portion of the second portion of the longitudinal catheter body for releasably securing at least one guide wire relative to the longitudinal catheter body.
