Patent number: 7169164Abstract: The invention provides a delivery system for placing devices in atrial appendages. The system includes a catheterization apparatus having a tubular structure with one or more nested tubes, wires, and shafts. The tubes establish a passageway for moving a device through a body's vasculature and heart into an atrial appendage. An expandable positioning guide is disposed on the distal end of a tube passing through the apparatus. The positioning guide is expanded in situ to engage atrial wall surfaces proximate to the atrial appendage for mechanical support. The deployed positioning guide mechanically stabilizes the device delivery passageway. A shaft passing through the tubes transports the device through the passageway to the atrial appendage. The system includes catheterization apparatus for transseptal delivery of the devices. An outer tube or sheath in the apparatus is used to penetrate and traverse the septum. An expandable securement device is disposed toward an end of the sheath.Type: GrantFiled: September 21, 2001Date of Patent: January 30, 2007Assignee: Atritech, Inc.Inventors: Thomas E Borillo, Gregg S Sutton

Publication number: 20030181942Abstract: Instrumentation for percutaneous delivery of blood filtration devices to atrial appendages includes a curved access sheath and a delivery tube. The curved access sheath is coursed through the patient's vasculature to gain transseptal access to a left atrial appendage. A compressed filter device attached to a tether wire is loaded in the delivery tube. The loaded delivery tube is advanced through the pre-positioned access sheath to place the device in a deployment position. 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. The expelled device, which is not constrained by the delivery tube walls, self expands to its useful size in the subject atrial appendage.Type: ApplicationFiled: January 24, 2003Publication date: September 25, 2003Inventors: Gregg S.

Publication number: 20030023266Abstract: Implant devices for modifying blood flow between an atrial appendage and its associated atrium, are customized for use in subject atrial appendages. The implant devices are tailored to uniquely match individual anatomical characteristics. Cardiac imaging techniques are used to obtain data on the size, shape and orientation of the subject atrial appendage. The raw imaging data is electronically processed using computer modeling to obtain multi-dimensional anatomical images of the subject atrial appendages.
