Intended Use

Nihon Kohden's TEC-7511A cardiolife and TEC-7521A cardiolife defibrillators are intended for medical purposes. The devices will deliver an electrical shock of a maximum of 360 joules of energy used for defibrillating (restoring normal heart mythm) the atria or ventricles of the heart or to terminate other cardiac arrhythmias. The devices deliver the electrical shock through paddles attached to the main unit. These devices will serve as a cardiac monitor, with the ability to measure heart rate and to sound an alarm when the falls outside preset upper and lower limits. The devices will also condition a physicilogical signal to be transmitted via radiofrequency from one location to another, e.g. a central monitoring station, and will recondition a physiological signal to the original format when received from another device, e.g. transmitter. The TEC-7511A cardiolife and TEC-7521A cardiolife will be available for use by a physician. or under the supervision of a physician, for adult and pediatric patients within a medical facility and in remote environment.

Regulatory Classification

Identification

Low-energy DC-defibrillator: A device that delivers into a 50 ohm test load an electrical shock of a maximum of 360 joules of energy used for defibrillating (restoring normal heart rhythm) the atria or ventricles of the heart or to terminate other cardiac arrhythmias. This generic type of device includes low energy defibrillators with a maximum electrical output of less than 360 joules of energy that are used in pediatric defibrillation or in cardiac surgery. The device may either synchronize the shock with the proper phase of the electrocardiogram or may operate asynchronously. The device delivers the electrical shock through paddles placed either directly across the heart or on the surface of the body. High-energy DC-defibrillator: A device that delivers into a 50 ohm test load an electrical shock of greater than 360 joules of energy used for defibrillating the atria or ventricles of the heart or to terminate other cardiac arrhythmias. The device may either synchronize the shock with the proper phase of the electrocardiogram or may operate asynchronously. The device delivers the electrical shock through paddles placed either directly across the heart or on the surface of the body.

The device is classified as Class II by the Division of Cardiovascular, Respiratory and Neurological Devices and the Cardiovascular Device Classification Panel under 21 CFR Part 870.5300 DC-Defibrillator, Low-energy (including paddles) as per Product Classification Code 74 LDD, under 21 CFR Part 870.2300 Cardiac Monitor (including Cardiotachometer and Rate Alam) as per Product Classification Code 74 DRT and under 21 CFR Part 870.2010 Radiofrequency Physiological Signal Transmitter and Receiver as per Product Classification Code 74 DRG.

Common names for the TEC-7511A cardiolife and the TEC-7521A cardiolife include Low-energy DC-defibrillator, Cardiac Monitor, Radiofrequency Physiological Signal Receiver and Radiofrequency Physiological Signal Transmitter.

The predicate devices are the Nihon Kohden TEC-7200A cardiolife Portable Defibrillator per 510(k) #K863405. commercial distribution cated October 31. 1986. the Nihon Kohden TEC-8250A cardiolife Portable Defibrillator per 510(k) #K914971, commercial distribution certification dated December 3, 1991, the Nihon Kohden BSM-8800A Life Scope 14 Bedside Monitor, per 510(k) #K920154, commercial distribution certification dated December 18, 1992 and the Nihon Kohden BSM-2101A Life Scope L Bedside Monitor per 510(k) #K914092, commercial distribution certification dated May 28, 1992.

Nihon Kohden's TEC-7511A and TEC-7521A cardiolife defibrillators are intended for medical purposes. These devices will deliver an electical shock of a maximum of 360 joules of energy used for defibiliating (restoring normal heart rhythm) the atria or ventricles of the heart or to terminate other cardiac arthythmias. The devices deliver the electrical shock through paddles attached to the main unit. The devices will serve as a cardiac monitor, with the ability to measure heart rate and to sound an alam when the heart rate falls outside preset upper and lower limits. The devices will also condition a physiological signal to be transmitted via radiofrequency from one location to another. e.o. a central monitoring station. and will recondition a physiological signal to the original format when received from another device, e.g. transmitter. The TEC-7511A and TEC-7521A cardiolife will be available for use by a physician, or under the supervision of a physician, within a medical facility and in remote environment.

To date, no performance standards or special controls are known or established for this device as required by Section 514 of the Food, Drug and Cosmetic Act and implemented by 21 CFR Part 861.

The TEC-7511A cardiolife and the TEC-7521A cardiolife were subject to electromagnetic, environmental, safety and performance testing procedures. These tests verified the operation of the device. Software validation tested the operation of the software functions of acquiring, processing, displaying and recording of the devices. The results confirmed that the devices performed within specifications.

Therefore based on the preceding information, Nihon Kohden believes that the TEC-7511A cardiolife Portable Defibrillator and the TEC-7521A cardiolife Portable Defibrillator are substantially equivalent to the predicate devices: the Nihon Kohden TEC-7200A cardiolife Portable Defibrillator, the Nihon Kohden TEC-8250A cardiolife Portable Defibrillator, the Nihon Kohden BSM-8800A Life Scope 14 Bedside Monitor and the Nihon Kohden BSM-2101A Life Scope L Bedside Monitor.
