The Cadwell EasyNet Nasal Pressure Module collects respiratory airflow data for adult and pediatric patients. The data is transmitted to a Cadwell EasyNet enabled system where it is displayed. The module may be used in a hospital, clinical or ambulatory setting for EEG studies, sleep disorder studies and other neuromonitoring and neurodiagnostic studies.

The Cadwell EasyNet® Nasal Pressure Module provides respiratory airflow data to Cadwell EasyNet® enabled systems. It outputs a digital representation of the data using the Cadwell proprietary EasyNet® communications protocol. The module measures 2 x 1.4 x .8 inches. It weighs about an ounce and is attached to the patient's chest or shoulder with elastic straps. An oral/nasal cannula is attached from the module to a patient's nose and mouth. A single small cable connects the device to the EasyNet® enabled system. The module requires no routine calibration or maintenance. The Nasal Pressure module determines functional respiratory airflow by recording pressure changes at the nose and mouth.

The Cadwell TES-1 constant voltage electrical stimulator is intended for cortical stimulation. The TES-1 is intended for intraoperative diagnosis of acute dysfunction in corticospinal axonal conduction brought about by mechanical trauma (traction, shearing, laceration, or compression) or vascular insufficiency. The Cadwell TES-1 Constant Voltage Stimulator is an accessory to the Cadwell Cascade Intra-operative monitoring system only. It is not a stand-alone device nor is it compatible with other systems.

The Cadwell Easy Body Position Module is intended for use to detect body positions during physiological recording. It provides output data that corresponds to five body positions (supine, prone, left side, right side and sitting up). It may be used in a clinical or ambulatory setting for both EEG and sleep disorder studies.

Kilowin is an electroneurodiagnostic device designed to measure and display the electrical signals generated by peripheral nerve, muscle and central nervous system. It will acquire the data necessary for electroencephalography (EEG), system. It will dequiry (ENG), electrocardiography (ECG), electromyography (EMG), nerve conduction velocity (NCV, F wave, and H reflex), evoked potentials (EP, brainstem, visual, somatosensory), repetitive nerve stimulation and sleep assessment. The Kilowin instrument is designed for use during the duration of the procedure only. Use of the proposed device is to be administered under the direction of a trained physician, surgeon, neurologist, or electrophysiologist in an operating room or clinic. The Kilowin device(s) are intended for use during electroencephalography (EEG), electronystagmography (ENG), electromyography (EMG), nerve conduction velocity (NCV, F wave, and H reflex), evoked potentials (brainstem, visual, somatosensory), repetitive nerve stimulation testing and sleep assessment.

to perform the measurements needed for electromyography (EMG), nerve conduction velocity (NCV, F wave, and H reflex), and evoked potentials (brainstem, visual, and somatosensory), and repetitive nerve stimulation. The purpose of the proposed device is to allow compatibility with high-impedance electrodes. The proposed device allows electrode inouts to be made closer to the source of the signal for reduced signal noise during procedures requiring high-impedance electrodes.

The proposed device consists of the existing four-channel preamplifier and a buffered electrode input box with extension cable. These components provide electrode inputs that are closer to the source of the signal during electromyographic (EMG) testing. The intent of this design is to reduce signal noise during procedures requiring high-impedance electrodes. The proposed device is for use with the Cadwell Sierra (K924723) and 6200A (K931428) EMG instruments. All device components are reusable and supplied non-sterile. The extension cable with electrode input box is compatible with EtO sterilization guidelines for procedures requiring a sterile field. The input box is available with separate active and reference input connectors or a single phono jack connector. The attached extension cable connects the input box to the preamplifier by way of a cable adapter. The existing preamplifier will be fitted with three pin DIN connectors to accept the cable adapter. The extension cable with buffered electrode input box allows electrode inputs to be made closer to the source of the signal for reduced signal noise during procedures requiring high-impedance electrodes. The electrode input box is available with separate active (labeled .) and reference connectors or a single phono jack connector to accommodate recording electrodes with these connector types. The input box is enclosed in a white polyethylene foam sheath. The sheath houses a circuit board consisting of a buffer circuit, two electrostatic discharge (ESD) networks (one on each side of the buffer circuit), and a separate circuit designed to limit fault currents. The circuit board is attached to a polyvinyl chloride extension cable terminated in an eight-pin DIN connector. The input box and extension cable are connected to the preamplifier by way of a polyvinyl chloride cable adapter terminated in a three-pin DIN connector. The adapter cable does not qualify as a class II device.
