  • Publication number: 20210330380
    Abstract: A method for the treatment of a patient for the purpose of lowering blood pressure and/or treating other medical conditions such as cardiac arrhythmias. A catheter having an ablation element is placed inside the body of a patient and is directed to a targeted location either on in the abdominal aorta where the right or left renal arteries branch from the aorta at or near the superior junction or ostia or on the inside of the inferior vena cava near the junction with the right renal vein or in the left renal vein at a position spatially near where the left renal artery branches from the abdominal aorta. Catheters designed for use in the method where these targeted locations are also disclosed and claimed.

  • Patent number: 9717555
    Abstract: A catheter includes an elongated body, a distal assembly with a shape-memory member defining a generally helical form, and a control handle. The control handle may be adapted to actuate a deflection puller wire for deflecting a portion of the elongated body and a contraction wire for contracting the generally helical form. The generally helical form carries irrigated ablation ring electrodes. A nitinol support member with shape memory extends through the distal assembly and into the elongated body to provide the helical form. The support member may have a varying stiffness along its length, for example, a decreasing stiffness toward a distal end of the support member. The support member can also be hollow so that it can receive a mandrel whose stiffness is greater than that of the support member.

  • Publication number: 20120197377
    Abstract: An apparatus for deployment and retrieval of a self-expanding intravascular stent includes an intravascular delivery wire and one or more rings of compliant material fixedly mounted over at least a portion of the intravascular delivery wire. The distal portion of the intravascular delivery wire can be stepped, having a smaller diameter than the proximal portion, and forming a hard stop. Distal and proximal bands can also be provided on the intravascular delivery wire to form hard stops. A self-expanding intravascular stent can releasably retained on the compliant material.
