Patent number: 9468751Abstract: Methods and apparatus for anchoring an implanted elongate medical device in a body portal, for example, a stimulation lead in a cranial burr hole, employ a securing element attached to an upper surface of a plate member, and moveable relative thereto, from an open position, at which the device may be inserted into a slot of the plate member, and a closed position, at which an engagement surface of the securing element anchors the inserted device. The securing element may extend at angle, with respect to a plane of the plate member, in the open position, and rotating the securing element lifts the engagement surface into the closed position. A locking member preferably extends from an upper surface of the plate member, and, when a latching portion of the securing element moves into engagement with the locking member, the element is moved into the closed position and secured thereat.Type: GrantFiled: March 12, 2013Date of Patent: October 18, 2016Assignee: Medtronic, Inc.Inventor: Eric H.

Patent number: 9468754Abstract: Selective sensing implantable medical leads include pulsing and sensing portions and pulsing and not sensing portion. Leads and electrodes may be used in defibrillation and as integrated bipolar defibrillation electrodes. An entire electrode can pass charge while a valve metal or valve metal oxide portion of the electrode prevents the entire electrode from sensing, effectively rejecting unwanted signals. Differential conduction pathways, due to the valve metal and/or oxides thereof, cause the portions of the electrodes to conduct differently when used anodically and cathodically. Complex intracardiac electrical gradient can be formed along with a number of virtual electrodes within the tissue. Reentrant loops can thereby be pinned following defibrillation shock.Type: GrantFiled: May 29, 2009Date of Patent: October 18, 2016Assignee: Medtronic, Inc.Inventors: Gonzalo Martinez, Timothy G. Laske, Mark T. Marshall

Patent number: 9468773Abstract: A tethering feature includes an elongate break-away member and a base, and forms a proximal end of an implantable medical device housing. A tether attachment zone of the break-away member extends between break-away member ends, and the base includes a pair of supports, wherein each end of the break-away member is wrapped around a corresponding support. A delivery catheter tether may be attached to the device tethering feature by passing a looped portion of the tether around the tether attachment zone. The device may be untethered from the catheter by applying a pull force through the attached tether, while a distal end of a shaft of the catheter, which abuts the device proximal end, provides a back-up force, the pull force unwrapping each end of break-away member from the corresponding base support.Type: GrantFiled: May 7, 2015Date of Patent: October 18, 2016Assignee: Medtronic, Inc.Inventors: Thomas A Anderson, Vladimir Grubac, Michael C Jacobs

Patent number: 9468392Abstract: Techniques for determining paced cardiac depolarization waveform morphological templates are described. For example, an implantable medical device (IMD) may sense a cardiac electrogram of a heart, identify cardiac depolarizations within the cardiac electrogram, and determine that the cardiac depolarizations are paced cardiac depolarizations resulting from delivery of a pacing pulse to the heart by another IMD without detecting the pacing pulse and without communicating with the other IMD. The IMD may identify paced cardiac depolarization waveforms of the paced cardiac depolarizations, determine a paced cardiac depolarization waveform morphological template based on the identified paced cardiac depolarization waveforms, determine a normal cardiac depolarization waveform morphological template based on the paced cardiac depolarization waveform morphological template, and compare the normal cardiac depolarization waveform morphological template to subsequent cardiac depolarization waveforms.Type: GrantFiled: February 6, 2015Date of Patent: October 18, 2016Assignee: Medtronic, Inc.Inventor: Troy E.
