US Patent:

6669692, Dec 30, 2003

Filed:

Aug 21, 2000

Appl. No.:

09/642202

Inventors:

Dale Nelson - Minneapolis MN
Steven D. Savage - Paynesville MN
William Penny - Arden Hill MN
Jeffrey Santer - Spring Lake Park MN

Assignee:

Biosense Webster, Inc. - Diamond Bar CA

International Classification:

A61B 1818

US Classification:

606 41, 606 47, 606129

Abstract:

The ablation catheter is comprised of a guiding catheter and an inner catheter. The guiding catheter is comprised of a shaft section which is attached to an articulating section at its distal end and a first handle at its proximal end. The inner catheter is comprised of an elongated central shaft, an electrode assembly attached to the distal end of the central shaft, and a second handle attached to the proximal end of the central shaft. The electrode assembly is comprised of a flexible plastic catheter tube having an outer surface, a porous tip electrode, and at least one linear electrode carried on the outer surface of the catheter tube. The electrode assembly is articulated to better align the electrode assembly to the generally arcuate shape of the inner chambers of the heart.

International Classification:

A61M 2900

US Classification:

606200

Abstract:

A distal protection device for use in a body lumen. The device includes a functional element which may be a filter or an occlusive element. The device includes means for controlling the movement and placement of the functional element along a guidewire. Motion of the guidewire can be independent of the motion of the functional element.

Assignee:

AGA Medical Corporation - Golden Valley MN

International Classification:

A61B 17/08

US Classification:

606213000

Abstract:

A method and apparatus for providing safe and efficient transcatheter correction of the shape of heart chambers, valves, or other body members. The apparatus generally performs this correction by securing a tether to body surfaces. The attachment device includes an anchor comprising a wire braid and at least one clamp affixed to and constraining a portion of the wire braid, the clamp having threading for temporarily coupling the anchor to a delivery member and an internal lumen through which the tether can pass. The device also includes a locking member cooperating with the lumen to lock the tether to the clamp at a preselected position along the length of the tether.
