Abstract:
1. A system for advancing a medical device over multiple guidewires, the system comprising: a first guidewire; a second guidewire; a guiderail having a length and including a guiderail housing, the guiderail housing defining a first guidewire lumen and a second guidewire lumen, both the first guidewire lumen and the second guidewire lumen extending the entire length of the guiderail, wherein the guiderail housing defines a first longitudinal opening extending from the first guidewire lumen to an exterior of the guiderail along the entire length of the first guidewire lumen and a second longitudinal opening extending from the second guidewire lumen to the exterior of the guiderail along the entire length of the second guidewire lumen, wherein the guiderail is configured to be advanced over at least one of the first guidewire and the second guidewire in a vessel; and a catheter having a first guidewire lumen configured to receive the first guidewire and a second guidewire lumen configured to receive the second guidewire, wherein the catheter is configured to be advanced over the first guidewire and the second guidewire to a target region in the vessel, wherein the advancement of the catheter over the first guidewire and the second guidewire pulls the first guidewire completely out of the first guidewire lumen through the first longitudinal opening and pulls the second guidewire completely out of the second guidewire lumen through the second longitudinal opening.
