Publication number: 20120157927Abstract: Some embodiments of a medical anchor device include an elongate body coupled with deployable subcutaneous anchors to secure a catheter instrument (or other medical instrument) in place relative to a skin penetration point. In some circumstances, the elongate body may be in the form of catheter hub body, and the subcutaneous anchors can be deployed from the hub body by adjustment of a movable actuator. A locking member can interact with the actuator so as to retain the actuator in the deployed orientation during the medical procedure.Type: ApplicationFiled: March 2, 2012Publication date: June 21, 2012Inventors: Michael S. Rosenberg, Mark R. Christianson, Kyle P. Taylor, Andrew T. Forsberg, Edward A. Barlow

Patent number: 8147459Abstract: Some embodiments of a medical device anchor system include an anchor sleeve that receives a catheter (or other medical instrument) though a working channel of the anchor sleeve. The anchor sleeve may include a first actuator that controls the extension of one or more subcutaneous tines into the subcutaneous region under the skin. The anchor sleeve can also include a second actuator that can cause the anchor sleeve to lock onto an outer portion of the catheter (or other medical instrument) arrange in the working channel.Type: GrantFiled: October 1, 2008Date of Patent: April 3, 2012Assignee: Interrad Medical, Inc.Inventors: Michael S. Rosenberg, Mark R. Christianson

Publication number: 20120078191Abstract: Some embodiments of a medical device anchor system include an anchor device that secures a medical instrument (such as a catheter or the like) in place relative to a skin penetration point using subcutaneous anchors. In some implementations, the anchor device can be installed using a technique in which the subcutaneous anchors undergo relatively little or no flexing when being inserted through the skin into the subcutaneous region between the skin and underlying muscle tissue which may be occupied by fatty tissue.Type: ApplicationFiled: September 29, 2010Publication date: March 29, 2012Applicant: INTERRAD Medical, Inc.Inventors: Michael S.

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

Publication number: 20100204656Abstract: Some embodiments of a medical device anchor system include an anchor device that receives a catheter (or other medical instrument) and secures the catheter in place relative to a skin penetration point. In some embodiments, the anchor device can secure the catheter in an operative position relative to the skin without the use of sutures or skin tapes. In particular embodiments, the anchor device can be adjusted to a folded condition so that subcutaneous anchors are partially rotated prior to removal from the skin penetration point.Type: ApplicationFiled: February 6, 2009Publication date: August 12, 2010Applicant: INTERRAD MEDICAL, INC.Inventors: MICHAEL S.
