摘要： An implant delivery system, comprising: an implantable device comprising a plurality of supports extending between a proximal end and a distal end, the supports being moveable between a collapsed configuration and an expanded configuration, a proximal guide tube at the proximal end of the supports extending toward the distal end, and a distal guide tube at the distal end of the supports extending toward the proximal end, wherein the proximal and distal guide tubes are telescoping and become further engaged as the supports move from the collapsed to the expanded configuration.

摘要： Instrumentation for percutaneous delivery of blood filtration devices to atrial appendages includes a curved access sheath and a delivery tube. A compressed filter device attached to a tether wire is loaded in the delivery tube. The access sheath and the delivery tube can be mechanically locked and moved together to place the device in a suitable deployment position. The device is deployed by expelling it from the delivery tube either by retracting the delivery tube over the tether wire, or by moving the tether wire forward through the delivery tube. A filter membrane in the deployed device extends across the appendage ostium to filter blood flow through the ostium. The filter membrane is configured to present a flat surface to atrial blood flow past the ostium.

摘要： 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. The membranes may have anticoagulants to help prevent thrombosis. The membranes be porous such that endothelial cells cover the membrane presenting a living membrane wall to prevent thrombosis. The membranes may have means to center the membranes over the ostium. Sensors may be attached to the membrane to provide information about the patient.

摘要： A method of preventing ingress of material into the left atrium of a heart includes providing a delivery sheath, advancing the sheath distal end through an opening between the right atrium and the left atrium of the heart, providing an expandable cage, delivering the expandable cage to the left atrium, and expanding the expandable cage within the left atrium. The expandable cage includes a proximal end, a distal end, and a plurality of supports extending therebetween. The expandable cage also includes a first membrane provided at its proximal end and a second membrane provided at its distal end. The expandable cage has a collapsed configuration so that it can be received within the lumen of the delivery sheath, and an expanded configuration for deployment within the heart. When expanded, the first membrane is positioned at an opening between the left and right atria of the heart, and the second membrane is positioned at the ostium of the left atrial appendage. The first membrane substantially prevents passage of blood between the atria and the second membrane prevents passage of embolic material from the left atrial appendage into the left atrium of the heart.
