US Patent:

6551303, Apr 22, 2003

Filed:

Oct 27, 1999

Appl. No.:

09/428008

Inventors:

Robert A. Van Tassel - Excelsior MN
Robert G. Hauser - Long Lake MN

Assignee:

Atritech, Inc. - Plymouth MN

International Classification:

A61M 3100

US Classification:

604508, 604104, 128898, 606200

Abstract:

A membrane applied to the ostium of an atrial appendage for blocking blood from entering the atrial appendage which can form blood clots therein is disclosed. The membrane also prevents blood clots in the atrial appendage from escaping therefrom and entering the blood stream which can result in a blocked blood vessel, leading to strokes and heart attacks. The membranes are percutaneously installed in patients experiencing atrial fibrillations and other heart conditions where thrombosis may form in the atrial appendages. A variety of means for securing the membranes in place are disclosed. The membranes may be held in place over the ostium of the atrial appendage or fill the inside of the atrial appendage. The means for holding the membranes in place over the ostium of the atrial appendages include prongs, stents, anchors with tethers or springs, disks with tethers or springs, umbrellas, spiral springs filling the atrial appendages, and adhesives. After the membrane is in place a filler substance may be added inside the atrial appendage to reduce the volume, help seal the membrane against the ostium or clot the blood in the atrial appendage.

US Classification:

606200, 606151, 623 237, 128898

Abstract:

A membrane applied to the ostium of an atrial appendage is disclosed. The membrane prevents blood clots in the atrial appendage from escaping therefrom and entering the blood stream which can result in a blocked blood vessel, leading to strokes and heart attacks. The membrane may be permeable or impermeable with respect to blood flow. The membrane is configured to extend over the ostium of the left atrial appendage. The membrane has an outer periphery with a dimension larger than a corresponding dimension of the ostium. Securement means is provided to secure the outer periphery of the membrane in direct engagement with the atrial wall surrounding the ostium. The securement means may located between the membrane and the atrial wall, or the securement means may extend distally from the membrane through the ostium.

International Classification:

A61M 2900

US Classification:

606200

Abstract:

Apparatus for permanent placement across an ostium of a left atrial appendage in a patient, which includes a filtering membrane configured to extend across the ostium of the left atrial appendage. The filtering membrane has a permeable structure which allows blood to flow through but substantially inhibits thrombus from passing therethrough. The apparatus also includes a support structure comprising a plurality of fingers which are radially outwardly expandable with respect to a longitudinal axis to permanently engage the interior wall of the left atrial appendage, wherein the filtering membrane is attached to the support structure extending across the ostium of the left atrial appendage.

Abstract:

Apparatus for permanent placement across an ostium of a left atrial appendage in a patient, which includes a filtering membrane configured to extend across the ostium of the left atrial appendage. The filtering membrane has a permeable structure which allows blood to flow through but substantially inhibits thrombus from passing therethrough. The apparatus also includes a support structure attached to the filtering membrane which retains the filtering membrane in position across the ostium of the left atrial appendage by permanently engaging a portion of the interior wall of the left atrial appendage. The support structure may be radially expandable from a first configuration to a second configuration which engages the ostium or the interior wall of the left atrial appendage. The filtering membrane may define an opening therethrough that is configured to expand from a first size which inhibits the passage of thrombus therethrough to a second size which allows an interventional device, e. g. , an expansion balloon, to pass therethrough, and wherein the opening is resiliently biased towards the first size.

Inventors:

Robert G. Hauser - Long Lake MN, US
Roger W. Dahl - Andover MN, US
Bruce H. KenKnight - Robbinsdale MN, US

Assignee:

Cardiac Pacemakers, Inc. - Saint Paul MN

International Classification:

A61N 1/39

US Classification:

607 5

Abstract:

A pulse generator housing for enclosing and containing pulse generator defibrillation circuitry. The housing is formed entirely of electrically conductive metal defining an electrically conductive outer surface which is connected to the pulse generator circuitry for delivering defibrillating energy to the heart. The pulse generator housing is implanted in the pectoral region proximate the heart with the conductive surface facing the heart. Regions of the conductive outer surface may be electrically isolated and dedicated for separately sensing and shocking. The outer surface may be coated with platinum. Additional coiled segment electrodes may extend from the housing and be electrically connected to the conductive outer surface so as to increase the effective conductive surface area. A sensor is provided to determine whether the housing is inside or outside a body of a patient to disconnect the pulse generator housing conductive surface from the pulse generator circuitry when the unit is outside the body of a patient.
