Patent number: 8375553Abstract: In one illustrative example, a device for sealing an opening in a vessel wall and/or tissue tract may include an anchor, a filament, a plug, and a knot. The anchor may be configured to be disposed adjacent to an interior surface of the vessel wall adjacent the opening in the vessel wall. The filament may have a distal end coupled to the anchor and may be configured to extend proximally through the vessel opening and/or tissue tract. The plug may be disposed about at least a portion of the filament member. The knot may be disposed about the filament proximal of the plug and may be configured to move over the filament and secure the plug relative to the anchor. The knot may be independent of the filament member.Type: GrantFiled: July 22, 2010Date of Patent: February 19, 2013Assignee: Boston Scientific Scimed, Inc.Inventors: Michael Pikus, Leonard B. Richardson, Joe Groff, James G. Hansen

Publication number: 20120065554Abstract: A balloon arrangement provided at a distal end of the catheter is configured for deployment within a vessel and comprises a distal balloon and a proximal balloon spaced apart from the distal balloon. An ablation arrangement is provided at the distal end of the catheter and configured to ablate target tissue proximate the vessel. A vessel deformation arrangement comprises at least a portion of the balloon arrangement and is configured to draw a wall segment of the vessel and the target tissue inwardly towards the ablation arrangement. The vessel deformation arrangement may include a port provided in a section of the shaft between the distal and proximal balloons. The port and balloon arrangement are configured to cooperatively draw the wall segment of the vessel and the target tissue inwardly towards the ablation arrangement in response to a negative pressure developed at the port.Type: ApplicationFiled: September 8, 2011Publication date: March 15, 2012Inventor: Michael Pikus

Publication number: 20080045892Abstract: An advancer system is described for moving an elongate medical device within a body. The system includes a drive unit having a motor. The drive unit is configured to translate movement of the motor to the device so as to alternately advance and retract the device relative to the body. The advancer system also includes a user-operable control system configured to control the drive unit. The control system can interface with a magnetic navigation system. The above-described system allows an operating physician to control catheter advancement and retraction while remaining outside an x-ray imaging field. Thus the physician is freed from repeated x-ray exposure.Type: ApplicationFiled: June 28, 2007Publication date: February 21, 2008Inventors: Steven Ferry, Jennifer Finney, Cam Habeger, Vincent Hackenmueller, Andrew Hall, Reed Houge, Scott Klimek, Michael Pikus
