An electrical stimulation system to provide pulse stimulation to an area of a living body by way of one or more electrode leads applied to the area, the area including an associated resistance element and an associated capacitance element. The system may include a pulse generating circuit having a controllable output voltage to generate constant voltage pulses to the one or more electrode leads, wherein the corresponding current signal of each constant voltage pulse includes an exponential decay to a steady state current value. The system may include a controller configured to estimate the associated resistance element of the area, determine a specified target steady state current value to be applied to the area, and control the pulse generating circuit to generate a constant voltage pulse to the one or more electrode leads at a calculated voltage level which achieves the specified target steady state current value to the area.

Electrical stimulation system with pulse control

A signal management system is disclosed which integrates a patient switching box and an amplification unit into a single compact enclosure sufficiently small to reside by the patient table in an operating unit set up for electrophysiology procedures. The system includes a front panel designed to accept standard ECG leads, a plurality of intracardiac leads, including leads available for stimulation and/or lesion generation, and a plurality of pressure channels. The front panel also includes a touch screen display to allow quick assignments of labels to each of the ECG or intracardiac leads and the pressure channels. The system includes an onboard microprocessor which allows any operation performed on the System to be automatically updated on a remote computer processing unit if attached, and vice-versa. Digital signal processors are used in the system to perform switching operations on the electrical signals received, and to perform gain, limiting and/or filtering processes thereon. The digital signal processors are automatically calibrated to adjust for varying gain and phase performance of the inputting front-end amplifiers which deliver the electrical signals from the intracardiac leads.

Integrated electrical signal switching and amplifying system

A versatile electrophysiology system including an amplification system, an ablation machine, a filter box, a display monitor and a chart recorder as well as an optional data management and analysis system wherein the amplification system receives endocardial signals from an ablation catheter during both the electrophysiology study and the ablation procedure and wherein the amplification system, ablation machine and ablation catheter are interconnected with the filter box such that the endocardial signals and the high energy ablation signal pass therethrough and are filtered thereby.

Electrophysiology filtering system

A versatile electrophysiology study monitoring system including an amplification system, a real time display monitor and a chart recorder as well as an optional data management and analysis system wherein the display monitor and chart recorder are controllable directly from the amplification system which may be positioned at the bedside of the patient to provide a portable system which may be used at the bedside of the patient or in the electrophysiology laboratory and which also includes a 32 channel display of physiological data and user settable filter settings for high and low pass filters.

A system for determining the first dental occlusion prematurity is presented. A sensor adapted to be inserted in the mouth of a patient comprises two flexible strips with spaced electrical conductors connected to a liquid crystal display. Each of the strips has a layer of dilatant material on one side. When the patient bites, the upper and lower conductors complete an electrical circuit and from the resistance of this circuit the location of the first prematurity relative to the strip is determined. One edge of the strip is used as a reference point on the sensor and the distance from this edge to the location is displayed on the liquid crystal display. The dilatant layer also retains the impression of the teeth and the location identified by the visual display and the impression are compared to give the exact location of the first prematurity. The sensor is reusable on the same patient to determine subsequent prematurities by squeezing it to remove the impression of teeth on the original bite.
