Patent number: 10285797Abstract: A permeable plug may be temporarily deployed in a patient to protect blood vessels from blockage by various debris. The plug includes a body formed from a filtering material. The body is collapsible for delivery to a location in a blood vessel and expandable to a filtering configuration in which the body occupies a cross-section of the blood vessel and is held in place by its own expansive force. At least one stud is connected to the body for use in deployment of the plug within the blood vessel and retrieval of the plug from the blood vessel.Type: GrantFiled: January 22, 2013Date of Patent: May 14, 2019Assignee: St. Jude Medical, LLCInventor: Steven S.

Publication number: 20150151081Abstract: A wire control catheter for aligning and guiding a guide wire through a lesion in a vessel is provided. The wire control catheter includes a shaft having a guide wire lumen and a control wire lumen. A control wire passes through the control wire lumen and is used in combination with an articulation structure to deflect or curve a distal tip portion of the catheter. The distal catheter shaft may include a centering device for centering the catheter within the vessel. The distal catheter shaft may also include a pre-dilation balloon for dilating the lesion prior to performing angioplasty or other treatment on the lesion. A method of treatment of a blood vessel includes inserting a guide wire into the blood vessel and advancing a control wire over the guide wire until the distal tip of the catheter is near the occlusion in the blood vessel. The tip of the catheter then is deflected via a control wire and an articulation structure. The guide wire is then advanced across the occlusion.Type: ApplicationFiled: February 11, 2015Publication date: June 4, 2015Inventors: Peter T. Keith, Dennis W. Wahr, Thomas V. Ressemann, David J. Blaeser, Timothy B. Petrick, Steven S. Hackett

Patent number: 7976564Abstract: Devices and methods for sealing a passageway formed by a patent foramen ovale (PFO track) in the heart are provided. One method includes providing an abrading device to the PFO track and abrading the tissue within the PFO track. The abraded tissue forming the PFO track is then held together under pressure, either via lowering right atrial pressure or via applying suction to the septum primum to pull it into apposition against the septum secundum. After a sufficient period of time, the pressure is released and the abraded tissue heals to form a robust seal over the PFO track. Additionally, several devices are provided which can be placed into the PFO track to apply adhesive to the walls of the PFO track. The devices may or may not be left within the PFO track. If the devices are not left within the PFO track, the walls of the PFO track, covered with adhesive, are brought into apposition with one another and adhered together.Type: GrantFiled: May 6, 2002Date of Patent: July 12, 2011Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: David J. Blaeser, Peter T. Keith, Jerome K. Grudem, Jr., Scott A. Olson, Steven S. Hackett, Thomas V. Ressemann, Joel D. Phillips, Mark R. Christianson, Dennis W. Wahr
