Patent number: 8886303Abstract: A pre-sutured anchor including a deformable anchor sleeve with a lumen sized to receive the therapy delivery element. An outer surface of the anchor sleeve including one or more annular compression grooves oriented generally co-axial to the lumen. At least one compression member is located in a compression groove in an open configuration. The compression member includes at least one stop. A suture material pre-tied in a self-locking compression knot extends around each compression member. The suture material includes distal ends adapted to receive a tension force that is transmitted as a radial compression force to deform the compression members and substantially engage the stop in a compressed configuration. The anchor sleeve compressively engages the therapy delivery element in the compressed configuration.Type: GrantFiled: April 5, 2013Date of Patent: November 11, 2014Assignee: Greatbatch, Ltd.Inventors: John Swoyer, Jesse Geroy, James Finley

Patent number: 8886340Abstract: The present application describes a retention device for anchoring a medical device within the vasculature. The device may include expandable member coupled to an intravascular medical device and proportioned for receipt within a vessel. At least a portion of the expandable member is expandable to radially engage a vessel wall and to thereby retain the medical device within the vessel. The system is suitable for a variety of intravascular devices, including but not limited to ICD's, pacemakers, and intravascular drug delivery systems.Type: GrantFiled: October 20, 2010Date of Patent: November 11, 2014Assignee: Interventional Autonomics CorporationInventors: Michael S. Williams, Terrance Ransbury, Richard A. Glenn, Kevin Holbrook

Patent number: 8868214Abstract: A cardiac electrode arrangement has one or several heart electrodes arranged on the exterior surface of a heart or attached to the heart from the outside and/or arranged with a pole in the cardiac tissue. The electrodes, which can be fixed in the operating position by an anchor, run to an implanted heart pacemaker. For positioning and affixing the anchor, a tool is used that is designed as a rod or stylet and acts on an attachment site of the anchor, whereby the anchor can be pushed into or through the myocardium. The anchor is, at the same time, attached to a tension element or thread, over which the electrode, which has an inner guide channel that accommodates the tension element or thread, can be moved in a fitted and controlled manner. In the operating position, the electrode can be connected to the tension element or thread located in the guide channel.Type: GrantFiled: July 14, 2006Date of Patent: October 21, 2014Assignee: Cardiac Pacemakers, Inc.Inventor: Peter Osypka

Patent number: 8801728Abstract: Leads having distal electrodes may be used in application of test stimulation for purposes of implanting a lead having a fixation element distal to an electrode array. The fixation element is proximal the distal electrode. Accordingly, the distal electrode may be advanced beyond a distal end of an introducer while the fixation element may be retained in a retracted configuration by the introducer. If the test signals applied by the distal electrode indicate that the distal electrode is in the desired location of the patient, a series of markings on the lead may be used to facilitate placement of the electrode array at the location previously occupied by the distal electrode; i.e. the desired location of the patient. The electrodes of the electrode array may then be used to provide therapy to the patient.Type: GrantFiled: January 21, 2011Date of Patent: August 12, 2014Assignee: Medtronic, Inc.Inventors: Martin T. Gerber, Michael D. Baudino

Patent number: 8792997Abstract: A peel-away lead implant tool is described. The peel away lead implant tool is adapted to be disposed over the terminal connector of a lead during an implantation procedure to protect the terminal connector. The peel-away lead implant tool includes a flexible polymer sheath including electrical contacts formed in a contact region of the sheath. The electrical contacts can be either metal foil contacts or conductive polymer contacts and extend from an outer surface to an inner surface of the sheath such that when the testing apparatus is coupled to the lead implant tool, the electrical contacts are pressed into electrical contact with the ring electrodes located on the terminal connector. The lead implant tool also includes various removal means facilitating the easy removal of the implant tool from the terminal connector when the implantation procedure is complete.Type: GrantFiled: January 16, 2014Date of Patent: July 29, 2014Assignee: Cardiac Pacemakers, Inc.Inventors: Bruce A.
