Patent number: 10350423Abstract: A device configured to deliver and deploy an implantable medical device (IMD) includes a handle assembly and a shaft extending distally therefrom. A device containment housing configured to accommodate the IMD is coupled to the distal region of the shaft. At least one of the shaft and device containment housing includes a compressible region that is configured to compress by an amount that is related to an applied force. The device may include a first position indicator and a second position indicator. An applied force causes the compressible region to compress by an amount that is related to the applied force, causing a change in distance between the first position indicator and the second position indicator and thus providing an indication of the applied force.Type: GrantFiled: February 2, 2017Date of Patent: July 16, 2019Assignee: CARDIAC PACEMAKERS, INC.Inventors: Allan Charles Shuros, Shibaji Shome, Brian Soltis, Brian L. Schmidt, Kevin John Stalsberg

Patent number: 9008771Abstract: Cardiac devices and methods discriminate non-captured intrinsic beats during evoked response detection and classification by comparing the features of a post-pace cardiac signal with expected features associated with a non-captured response with intrinsic activation. Detection of a non-captured response with intrinsic activation may be based on the peak amplitude and timing of the cardiac signal. The methods may be used to discriminate between a fusion or capture beat and a non-captured intrinsic beat. Discriminating between possible cardiac responses to the pacing pulse may be useful, for example, during automatic capture verification and/or a capture threshold test.Type: GrantFiled: March 5, 2012Date of Patent: April 14, 2015Assignee: Cardiac Pacemakers, Inc.Inventors: Yanting Dong, Scott A. Meyer, Kevin John Stalsberg

Patent number: 8923966Abstract: An apparatus comprises a cardiac signal sensing circuit, a pacing therapy circuit, and a controller circuit. The controller circuit includes a safety margin calculation circuit. The controller circuit initiates delivery of pacing stimulation energy to the heart using a first energy level, changes the energy level by at least one of: a) increasing the energy from the first energy level until detecting that the pacing stimulation energy induces stable capture, or b) reducing the energy from the first energy level until detecting that the stimulation energy fails to induce capture, and continues changing the stimulation energy level until confirming stable capture or the failure of capture. The safety margin calculation circuit calculates a safety margin of pacing stimulation energy using at least one of a determined stability of a parameter associated with evoked response and a determined range of energy levels corresponding to stable capture or intermittent failure of capture.Type: GrantFiled: September 19, 2013Date of Patent: December 30, 2014Assignee: Cardiac Pacemakers, Inc.Inventors: Amy Jean Brisben, Shibaji Shome, Kenneth N.

Patent number: 8831727Abstract: Methods and systems for detecting noise in cardiac pacing response classification processes involve determining that a cardiac response classification is possibly erroneous if unexpected signal content is detected. The unexpected signal content may comprise signal peaks that have polarity opposite to the polarity of peaks used to determine the cardiac response to pacing. Fusion/noise management processes include pacing at a relatively high energy level until capture is detected after a fusion, indeterminate, or possibly erroneous pacing response classification is made. The relatively high energy pacing pulses may be delivered until capture is detected or until a predetermined number of paces are delivered.Type: GrantFiled: September 14, 2012Date of Patent: September 9, 2014Assignee: Cardiac Pacemakers, Inc.Inventors: Kevin John Stalsberg, Yanting Dong, Scott A.

Patent number: 8521285Abstract: Methods and devices are described that allow estimation of an electrostimulation capture threshold, such as a dedicated bipolar pacing vector threshold. In an example, an equal-energy assumption between first and second pacing vectors can be used to estimate an electrostimulation capture threshold of a second pacing vector from a measured electrostimulation capture threshold of the first pacing vector and impedances of the first and second pacing vectors. In an example, a relationship between first and second pacing vectors can be determined from measured data, and a parameter of the relationship can be used with a measurement of an electrostimulation capture threshold of the first pacing vector to estimate an electrostimulation capture threshold of the second pacing vector.Type: GrantFiled: October 18, 2010Date of Patent: August 27, 2013Assignee: Cardiac Pacemakers, Inc.Inventors: Amy Jean Brisben, Aaron R.

Patent number: 8452405Abstract: Noncaptured atrial paces can result in long-short cardiac cycles which are proarrhythmic for ventricular tachyarrhythmia. Approaches are described which are directed to avoiding proarrhythmic long-short cycles. For cardiac cycles in which the atrial pace captures the atrium, a first post ventricular refractory period (PVARP) and a first A-A interval are used. For cardiac cycles in which the atrial pace does not capture the atrium, both an extended PVARP and an extended A-A interval are used. The A-A interval following a noncaptured atrial pace is extended from an atrial depolarization sensed during the extended PVARP.Type: GrantFiled: May 3, 2010Date of Patent: May 28, 2013Assignee: Cardiac Pacemakers, Inc.Inventors: Eric Enrooth, Yanting Dong, Kenneth N.
