Patent number: 10842998Abstract: Devices and methods for single therapy pulse (STP) therapy for tacharrythmia are disclosed. The STP therapy can be delivered from a far-field position to allow a “global” capture approach to pacing. Due to the global capture in STP, a series of pulses, which is indicative of conventional anti-tachycardia pacing (ATP) delivered by transvenous systems, becomes unnecessary. One to four pulses at most are needed for STP, and after delivery of the one to four pulses, therapy delivery can be interrupted to determine whether the previously delivered therapy has been successful.Type: GrantFiled: April 25, 2019Date of Patent: November 24, 2020Assignee: CAMERON HEALTH, INC.Inventors: James M. Keefe, Rick Sanghera

Patent number: 9380955Abstract: Tools and devices are provided for determining whether a patient is well suited to receiving an implantable cardiac stimulation device by analyzing cardiac signals captured using external or cutaneous electrodes. Some of the illustrative tools include shapes for visual comparison to printed ECG strips. Kits for use of illustrative tools are also shown. Automatic devices are also disclosed which perform at least some analytical functions electronically for a user. In an example, a printed ECG strip is visually compared to a shape in order to ensure a patient is well suited to receiving a cardiac stimulation device having a particular implant location and/or cardiac signal analysis method implementation.Type: GrantFiled: March 6, 2015Date of Patent: July 5, 2016Assignee: CAMERON HEALTH, INC.Inventors: Rick Sanghera, Alan F. Marcovecchio, James M. Keefe

Patent number: 8548573Abstract: Methods and implantable devices that detect cardiac events using dynamic filtering. Illustratively, default filtering is performed except for a predefined period of time following detection of cardiac events, during which post-beat filtering is performed instead. The example post-beat filtering applies a narrower pass-band to the signal than the default filtering in order to attenuate T-waves more greatly than the default filtering during a time period after a detected event that is expected to correspond to occurrence of T-waves.Type: GrantFiled: January 18, 2010Date of Patent: October 1, 2013Assignee: Cameron Health, Inc.Inventor: James M.
