Patent ID: 7104981

Claim:
A system for locally delivering therapy to a renal system in a patient, comprising: an introducer sheath with an elongate tubular body with a proximal end portion, a distal end portion that is adapted to be placed percutaneously into a patient across a vascular access site when the proximal end portion extends externally from the patient, and a delivery lumen extending along a longitudinal axis between a proximal port along the proximal end portion and a distal port along the distal end portion; and a proximal coupler assembly with a proximal portion and a distal portion; wherein the distal portion comprises a distal lumen and is coupled to the proximal port with the distal lumen substantially aligned with the longitudinal axis of the delivery lumen; wherein the proximal portion comprises a first branch lumen and a second branch lumen extending proximally from the distal lumen and terminating proximally at first and second entry ports, respectively; the first entry port is adapted to receive a percutaneous translumenal interventional device therethrough into the first branch lumen; the second entry port is adapted to receive a bilateral renal delivery device assembly therethrough and into the second branch lumen; and wherein the first and second branch lumens are of sufficient orientation relative to the distal lumen, and the first and second branch lumens and distal and delivery lumens are of sufficient dimension, such that each of the percutaneous translumenal interventional device and the bilateral renal delivery device may be slideably engaged simultaneously within the distal lumen and further within the delivery lumen without substantial mutual interference therebetween.
