Sheath for use in peripheral interventions
First Claim
1. A single lumen introducer sheath for accessing at least one renal artery and at least one peripheral blood vessel of a patient, the introducer sheath comprising:
- a proximal hub comprising first and second ports;
a lumen extending from the first and second ports and having sufficient length such that when the ports are positioned outside the patient a distal end of the lumen is positionable in an abdominal aorta at or near origins of the patient'"'"'s renal arteries;
a proximal aperture in the lumen, configured to allow passage of a vascular catheter device through the proximal aperture and into or through an iliac artery contralateral to an insertion point of the introducer sheath into the patient; and
a distal aperture at the distal end of the lumen, configured to allow passage of a bifurcated renal catheter device out of the distal aperture to enter at least one of the renal arteries.

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.

7. A method for advancing at least two catheter devices into vasculature of a patient, the method comprising:
-
positioning a single lumen introducer sheath in the patient such that the sheath extends from a proximal, two-port hub outside the patient into one of the patient'"'"'s iliac arteries, and thus to a distal end in an abdominal aorta at or near origins of renal arteries of the patient;
advancing a bifurcated renal artery catheter device through the distal end of the sheath'"'"'s lumen to extend into the renal arteries; and
advancing a vascular catheter device through a proximal aperture in the lumen into at least one peripheral vessel of the patient on a contralateral side of the patient relative to an insertion point of the sheath. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A method for advancing at least two catheter devices into vasculature of a patient, the method comprising:
-
positioning a dual lumen introducer sheath in the patient such that the sheath extends from a proximal hub outside the patient into one of the patient'"'"'s iliac arteries, and thus to a first distal aperture of a first lumen in an abdominal aorta at or near origins of renal arteries of the patient and to a second distal aperture of a second lumen in or near the iliac artery in which the sheath is positioned;
advancing a bifurcated renal artery catheter device through the first lumen and first distal aperture to extend into the renal arteries; and
advancing a vascular catheter device through the second lumen and second distal aperture into at least one peripheral vessel of the patient on a contralateral side of the patient relative to an insertion point of the sheath. - View Dependent Claims (15, 16, 17, 18, 19, 20)
