Publication number: 20100130852Abstract: A catheter system for positioning of a medical instrument that includes a first elongate member having a first lumen. The catheter system also includes a second elongate member that includes a second lumen that receives the medical instrument. The second elongate member is coupled directly to the first elongate member, and the second elongate member is operable to be at least partially segmented generally along a second longitudinal axis thereof to allow movement of the medical instrument outside the second lumen. The second elongate member is selectively collapsible and expandable to change a size of the second lumen.Type: ApplicationFiled: November 21, 2008Publication date: May 27, 2010Applicant: Medtronic, Inc.Inventors: Michael R.

Publication number: 20100125194Abstract: 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: ApplicationFiled: July 15, 2009Publication date: May 20, 2010Applicant: MEDTRONIC, INC.Inventors: Matthew Bonner, Kenneth Gardeski, Bruce R. Mehdizadeh, Roger Christopherson, Michael R. Neidert

Publication number: 20100082000Abstract: A catheter system for positioning of a medical instrument within a body. The catheter system includes a hub defining a main lumen therethrough for passage of the medical instrument. The catheter system also includes an elongate tubular member defining a lumen therethrough. The lumen of the elongate tubular member is in communication with the main lumen of the hub for further passage of the medical instrument. The elongate tubular member defines a first portion and a second portion. The catheter system also includes a reinforcement member that is fixedly coupled to and reinforces the elongate tubular member, the reinforcement member includes a first part, a second part, and a partition defined between the first and second parts. The first and second parts are adapted to selectively move away from each other along the partition to thereby move the first and second portions away from each other and to uncover the medical instrument.Type: ApplicationFiled: September 30, 2008Publication date: April 1, 2010Applicant: Medtronic, Inc.Inventors: Jordon Honeck, Ronan Thornton, Michael R. Neidert, Daniel Vinup

Publication number: 20100036238Abstract: A medical instrument assembly is disclosed. The medical instrument has proximal and distal ends. A receiver coil being mounted proximate to a distal end of the medical instrument, the receiver coil being electrically connectable at a proximal end of the medical instrument. A deployable object being disposed and movable within the medical instrument. The deployable object bearing a high magnetic permeability material located proximate to the receiver coil. The high magnetic permeability material and the receiver coil combining to form an inductive element having an inductance that varies in a predetermined manner with the position of the deployable device relative to the receiver coil. A determination of the inductance being performed at the proximal end of the delivery catheter indicates the extension of the deployable device through the medical instrument.Type: ApplicationFiled: June 12, 2009Publication date: February 11, 2010Applicant: Medtronic, Inc.Inventors: Michael R. Neidert, Kenneth C. Gardeski, Claude A. Vidal, Russell J. Redmond, Laurent G. Verard

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: 20090264862Abstract: A delivery device includes an outer sidewall and an inner sidewall extending therein. An outer surface of the inner sidewall defines a plurality of longitudinally extending grooves, each of which interlock with a corresponding inward protruding member of a plurality of longitudinally extending inward protruding members defined by an inner surface of the outer sidewall. A longitudinally extending lumen of the device, which may accommodate delivery of an implantable medical device, is defined, at least in part, by the inner surface of the inner sidewall. A slitting zone of the device, for example, provided by one of the sidewalls extending less than 360 degrees about a longitudinal axis of the device, enables removal of the delivery device from around the delivered device.Type: ApplicationFiled: April 15, 2009Publication date: October 22, 2009Applicant: Medtronic, Inc.Inventors: Michael R.

Publication number: 20090198298Abstract: A method and system for use in selecting a cardiac pacing site includes sensors for tracking wall motion (e.g., sensors coupled to the right and left ventricular heart wall). The wall motion of one or more non-paced cardiac cycles is compared to the wall motion of one or more paced cardiac cycles to determine the effectiveness of one or more pacing sites.

Publication number: 20090125078Abstract: A method for selecting a cardiac pacing site includes steps of: securing first and second electromagnetic receiver coils at first and second positions, respectively, along a heart wall; collecting a set of non-paced heart wall motion data from each of the coils secured at the corresponding positions; applying cardiac pacing stimulation at at least one first pacing site; collecting a first set of paced heart wall motion data from each of the secured coils; comparing the non-paced heart wall motion data to the first set of paced heart wall motion data; and determining, based on the comparing, whether to maintain pacing at the at least one first cardiac pacing site or to apply pacing stimulation at a second pacing site for collection of a second set of paced heart wall motion data. The at least one first pacing site may include a right ventricular site and a left ventricular site.Type: ApplicationFiled: October 3, 2008Publication date: May 14, 2009Applicant: MEDTRONIC, INC.Inventors: Daniel R.
