Benefits of technology

[0005] The invention comprises a conduit (such as an introducer sheath or a guide catheter) for use in an interventional procedure comprising: a main body having a length; at least one disruptable barrier within the main body extending along at least a portion of the length of the main body, defining at least two lumens within the main body; and wherein the barrier is adapted to be disrupted before or during the procedure to reduce the number of lumens within the main body. In an aspect of the invention the at least two lumens are adapted to receive separate elongated members (such as guide wires) and prevent the elongated members from tangling with each other.
[0006] An aspect of the invention comprises an introducer sheath that incorporates at least two separate lumens to prevent the entanglement of at least two guidewires. The lumens are separated by disruptable barrier(s) that allows multiple lumens to be converted into fewer lumens. Th

Problems solved by technology

A common problem associated with the use of multiple guidewires is the “crossing” or entanglement of the guidewires in the vasculature proximal to the treatment site.
Crossed and entangled guidewires prohibit or severely restrict the ability to advance a device with multiple gui

Embodiment Construction

[0037] A better understanding of the present invention may be had with reference to the several figures.

[0038] Shown in FIG. 1 is a schematic representation of the abdominal part of the aorta and its principal branches. The abdominal aorta 20 is characterized by a right renal artery 22 and left renal artery 24. The large terminal branches of the aorta are the right and left common iliac arteries 26 and 28. Each common iliac artery branches into internal 30 and external 32 iliac arteries. An external iliac artery 32 becomes the femoral artery below the inguinal ligament. Internal iliac artery 30 is also known as the hypogastric artery. Additional vessels (e.g., second lumbar, testicular, inferior mesenteric, middle sacral) have been omitted for simplification. The infrarenal aorta is that portion of the aorta disposed between the renal arteries and the common iliac arteries. Throughout this application the term “distal” refers to the direction that is furthest away from the clinicia...

Abstract

A conduit, such as an introducer sheath, catheter, or guide catheter, incorporating two or more separate lumens to prevent the entanglement of guidewires located at least partially within the conduit. The lumens are separated by at least one disruptable barrier that allows multiple lumens to be converted into fewer lumens prior to or as a device is advanced through the introducer sheath.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] Novel conduits, such as guide catheters and catheter introducer sheaths, for use in interventional procedures, particularly introducer sheaths adapted for use with multiple guidewires. [0003] 2. Description of Related Art [0004] It is often desirable to use multiple guidewires in various endovascular procedures. For example when deploying stent graft aneurismal repair devices within branched vasculature, a first guidewire would be used to access the main artery while second and / or third guidewires would access the side branched arteries. Stent grafts with multiple guidewire ports would then be advanced along the respective guidewires and deployed at the desired sites. A common problem associated with the use of multiple guidewires is the “crossing” or entanglement of the guidewires in the vasculature proximal to the treatment site. Crossed and entangled guidewires prohibit or severely restrict the ability to advance...
