Patent number: 8768434Abstract: An volume of a patient can be mapped with a system operable to identify a plurality of locations and save a plurality of locations of a mapping instrument. The mapping instrument can include one or more electrodes that can sense a voltage that can be correlated to a three dimensional location of the electrode at the time of the sensing or measurement. Therefore, a map of a volume can be determined based upon the sensing of the plurality of points without the use of other imaging devices. An implantable medical device can then be navigated relative to the mapping data.Type: GrantFiled: April 14, 2009Date of Patent: July 1, 2014Assignee: Medtronic, Inc.Inventors: H.

Publication number: 20130253346Abstract: In one example, this disclosure is directed to a kit for intravascular implantation of an implantable medical device, the kit comprising an outer sheath, the outer sheath sized to traverse a vasculature of the patient, and an elongated inner sheath with a tapered distal end. The inner sheath is slidable within the inner lumen of the outer sheath and is selectably removable from the inner lumen of the outer sheath by sliding the inner sheath out of the proximal opening of the outer sheath. The kit includes an elongated deployment receptacle including a deployment bay slidable within the inner lumen of the outer sheath when the inner sheath is not within the inner lumen of the outer sheath. The deployment bay carries an implantable medical device through the inner lumen of the outer sheath and facilitates deployment of the implantable medical device from the distal end of the outer sheath.Type: ApplicationFiled: May 29, 2012Publication date: September 26, 2013Applicant: MEDTRONIC, INC.Inventors: Erik C.

Publication number: 20130253343Abstract: In one example, this disclosure is directed to a kit for intravascular implantation of an implantable medical device within a patient, the kit comprising an elongated outer sheath forming a first inner lumen with a distal opening, the outer sheath sized to traverse a vasculature of the patient, and an elongated inner sheath forming a second inner lumen. An outer diameter of the inner sheath is smaller than the diameter of the first inner lumen such that the inner sheath fits within the first inner lumen, wherein the inner sheath is slidable within the first inner lumen. The second inner lumen at a distal end of the inner sheath is configured to carry an implantable medical device.

Patent number: 8486089Abstract: Devices and methods for implanting leads along a spinal cord include an introducer having a main body defining a lumen and one or more collapsible and expandable side sheaths attached to the main body. The side sheaths may be collapsed as the introducer is positioned in a desired location of a patient to maintain a low profile. Once the introducer is placed, the side sheaths may be expanded to receive a lead. A lead may also be inserted through a lumen of the main body. Once the leads are inserted, the introducer may be withdrawn over the leads, leaving the leads implanted in the desired region in a desired orientation.Type: GrantFiled: February 16, 2010Date of Patent: July 16, 2013Assignee: Medtronic, Inc.Inventors: Phillip C.

Patent number: 8135467Abstract: Bio-impedance may be used for navigation systems to chronically implant pacing and defibrillation leads in the heart using a non-fluoroscopic position sensing unit (PSU). Such a system requires that a conductive material, such as a retractable helical tip-electrode, be exposed during implantation. Since the tip is retracted during implantation, this disclosure provides a modified distal portion employing at least one aperture (or “window”) for fluid exposure of the helix-electrode and a deployable internal sleeve for covering the aperture(s) when the helix-electrode is extended.Type: GrantFiled: June 26, 2009Date of Patent: March 13, 2012Assignee: Medtronic, Inc.Inventors: H.

Publication number: 20110282289Abstract: Systems for gaining access into a body of a patient around an implanted body of an elongate medical device include a sheath having a deformable wall that allows insertion of the device body into a lumen surrounded by the sheath wall. The sheath wall may include first and second edges that extend from a proximal end to a distal end of the lumen, or just extend along a distal portion of the lumen. A tool, which includes a groove sized to grasp about a circumference of the device body, may facilitate insertion of the device body into the lumen of those sheath embodiments that include the first and second edges, by spreading at least one of the first and second edges of the wall apart from the other of the first and second edges while the device body is grasped within the tool.Type: ApplicationFiled: July 28, 2011Publication date: November 17, 2011Inventors: Randy A.
