Benefits of technology

[0011] In some embodiments, the first and second lumens are disposed side-by-side in a proximal portion of the introducer sheath, and the first lumen extends beyond the proximal portion. In some embodiments, the first lumen is configured to accept a bi

Problems solved by technology

In any event, these procedures often involve the use of radiocontrast agents known to have detrimental effects on renal function.
In patients with known risk factors, radiocontrast nephropathy (RCN) is a prevalent adverse effect of interventional procedures utilizing organically bound iodine-based

Embodiment Construction

[0026] Referring to FIG. 1, a vascular access system 10 in one embodiment suitably includes a dual lumen introducer sheath 12, a bifurcated renal catheter 14 and an additional vascular catheter device 16. As will be described in further detail below, in alternative embodiments, introducer sheath 12 may have only one lumen, with distal and proximal apertures. In the embodiment shown in FIG. 1, introducer sheath 12 includes a proximal hub 18 having two having first and second ports 24, 26, a first lumen 20 in fluid communication with first port 24 and a first distal aperture 28, and a second lumen 22 in fluid communication with second port 26 and a second distal aperture 30. Introducer sheath 12 is typically, though not necessarily, introduced into a patient through a femoral artery and advanced into an iliac artery, which in FIG. 1 is referred to as the ipsilateral iliac artery II. Upon positioning of sheath 12, first lumen 20 extends into the patients aorta A such that first distal ...

Abstract

A dual lumen introducer sheath provides access to at least one renal artery and at least one peripheral blood vessel of a patient. The introducer sheath includes a proximal hub comprising first and second ports, a first lumen, and a second lumen. The first lumen extends from the first port to a first distal aperture and has sufficient length such that when the first port is positioned outside the patient the first distal aperture is positionable in the abdominal aorta at or near origins of the patient's renal arteries. The second lumen extends from the second port to a second distal aperture, has a shorter length than the length of the first lumen, and is configured to allow passage of a catheter device through the second lumen and into or through an iliac artery contralateral to an insertion point of the introducer sheath into the patient.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS [0001] The present application claims priority to U.S. Provisional Patent Application Nos.: 60 / 550,632 (original attorney docket number FLO5360.56P1), filed Mar. 4, 2004, and 60 / 550,774, (original attorney docket number FLO5360.56P2), filed Mar. 5, 2004, the full disclosures of which are hereby incorporated by reference.BACKGROUND OF THE INVENTION [0002] The present invention is related to medical devices, methods and systems. More specifically, the invention is related to devices, methods and systems for accessing various blood vessels in a patient, such as one or both renal arteries and one or more peripheral vessels. [0003] In the setting of interventional radiology, numerous conditions exist that warrant placement of various intravascular devices into the lower limb arteries (iliac, femoral, popliteal, etc.). Such devices may include catheters and guidewires for diagnostic purposes, or systems for therapeutic or prophylactic applications ...
