Cameron Health is a medical device developer based in San Clemente, California, USA. Cameron Health has its European office, Cameron Health BV, in Arnhem, The Netherlands. The privately held company's focus is on a new generation of minimally invasive implantable cardioverter-defibrillator which they call a Subcutaneous Implantable Defibrillator . Cameron Health's approach avoids implanting transvenous leads into the heart, which has been the usual procedure for cardiac devices. Instead, the Cameron ICD is entirely implanted outside the thoracic wall. Wikipedia.

Source Type

In a subcutaneous implantable cardioverter/defibrillator, cardiac arrhythmias are detected to determine necessary therapeutic action. Cardiac signal information is sensed from far field electrodes implanted in a patient. The sensed cardiac signal information is then amplified and filtered. Parameters such as rate, QRS pulse width, cardiac QRS slew rate, amplitude and stability measures of these parameters from the filtered cardiac signal information are measured, processed and integrated to determine if the cardioverter/defibrillator needs to initiate therapeutic action.


The present invention is directed toward a detection architecture for use in implantable cardiac rhythm devices. The detection architecture of the present invention provides methods and devices for discriminating between arrhythmias. Moreover, by exploiting the enhanced specificity in the origin of the identified arrhythmia, the detection architecture can better discriminate between rhythms appropriate for device therapy and those that are not.

Implantable medical device systems and methods configured to use a detection profile selected from among a plurality of detection profiles to define a detection threshold for identifying cardiac events, in which a close call definition is used to determine which of the plurality of detection profiles is to be chosen. Upon identifying a close call, in which an overdetection nearly occurred but did not actually take place, a relatively less sensitive detection profile is chosen.

New methods for implanting a cardiac therapy system include implanting a lead of the system substernally anterior of the heart without attaching to the myocardium or pericardium. An illustration includes placement of an anchor beneath the sternum in the vicinity of one of the sternal angle, a location superior of the ventricles, the area bounded by the 2nd or 3rd ribs, and level with the aortic arch. A tension element or tether is attached to the anchor and a lead is introduced over the tension element or tether and secured in a desired position relative to the anchor. Other examples also include implantation, substernally, of a lead without the use of a pre-tunneling tool or sheath over the lead itself, for example by using an advancing tool for pushing the lead into position.

Methods and tool kits for implanting a lead subcutaneously. Examples include tool kits and methods for establishing first and second subcutaneous tunnels at an angle relative to one another to facilitate introduction of a lead to the subcutaneous space. In an example, a first insertion tool is used to establish a first subcutaneous tunnel, and a second insertion tool, with or without the use of a blunt dissector, sheath, guidewire, or steering mechanism, is used to initiate or form the second subcutaneous tunnel. Such methods and tool kits may reduce the number of incisions needed to implant a subcutaneous lead along a subcutaneous path having a curve therein.


Methods, implantable medical devices and systems configured to perform analysis of captured signals from implanted electrodes to identify cardiac arrhythmias. In an illustrative embodiment, signals captured from two or more sensing vectors are analyzed, where the signals are captured with a patient in at least first and second body positions. Analysis is performed to identify primary or default sensing vectors and/or templates for event detection.

Self-correlation enhancements and implementations are described. In particular, certain examples demonstrate the use of a tracking mechanism to identify and/or confirm cardiac rate using data from iterative self-correlation performed at intervals over time. This may enable the interpolation of cardiac rate in an implantable medical device when data is insufficient, and may provide confidence in cardiac rate analyses.

Electrical circuit componentry is switchable into a defibrillator circuit to deliver a constant pacing current to a patient. The circuitry may include a constant current source inserted in a leg of the defibrillator circuit or a resistor of selected value inserted between a high voltage source and the high side of a defibrillator circuit.
