Patent number: 9642555Abstract: An apparatus for subcutaneous lead guidance includes a flexible guide strap, a navigation catheter and a tunneling tool. The guide strap includes an upper layer having a plurality of retainer formations and a substrate attachable on a patient's skin extending between an incision and a target site. The navigation catheter is coupled to the upper layer via the retainer formations from a first end to a second end of the guide strap. The navigation catheter includes a plurality of position sensors for generating a subcutaneous navigation volume between the incision and the target site when the navigation catheter is coupled to a navigation system. The tunneling tool has a distal portion with a leading end and at least one position sensor on the distal portion for viewing digital representation of the distal portion in relation to the navigation volume on a display coupled to the navigation system.Type: GrantFiled: July 15, 2009Date of Patent: May 9, 2017Assignee: Medtronic, Inc.Inventors: Matthew Bonner, Kenneth Gardeski, Bruce R.

Publication number: 20100030061Abstract: An image guided navigation system for navigating a region of a patient which is gated using ECG signals to confirm diastole. The navigation system includes an imaging device, a tracking device, a controller, and a display. The imaging device generates images of the region of a patient. The tracking device tracks the location of the instrument in a region of the patient. The controller superimposes an icon representative of the instrument onto the images generated from the imaging device based upon the location of the instrument. The display displays the image with the superimposed instrument. The images and a registration process may be synchronized to a physiological event.Type: ApplicationFiled: July 31, 2008Publication date: February 4, 2010Inventors: Monte R. Canfield, Michael R.

Publication number: 20050165466Abstract: Methods and systems for transvenously accessing the pericardial space via the vascular system and atrial wall, particularly through the superior vena cava and right atrial wall, to deliver treatment in the pericardial space are disclosed. A steerable instrument is advanced transvenously into the right atrium of the heart, and a distal segment is deflected into the right atrial appendage. A fixation catheter is advanced employing the steerable instrument to affix a distal fixation mechanism to the atrial wall. A distal segment of an elongated medical device, e.g., a therapeutic catheter or an electrical medical lead, is advanced through the fixation catheter lumen, through the atrial wall, and into the pericardial space. The steerable guide catheter is removed, and the elongated medical device is coupled to an implantable medical device subcutaneously implanted in the thoracic region. The fixation catheter may be left in place.Type: ApplicationFiled: December 1, 2004Publication date: July 28, 2005Inventors: Mary Morris, Kenneth Gardeski, Michael Ujhelyi, Michael Leckrone
