Benefits of technology

"The present invention provides a method and apparatus for treating breathing disorders by sensing and stimulating the diaphragm to control movement of the diaphragm and thus manage respiration. The method and apparatus can detect and elicit diaphragm movement to cause respiration when respiratory parameters fall below a threshold level. The invention can programmed to match the patient's normal respiratory function and can also use position sensors to determine the patient's reclining or standing position to adjust treatment accordingly. The invention can be implanted and can deliver stimulating pulses to the diaphragm through electrodes placed on the phrenic nerve or on the diaphragm muscle. The invention can be programmed for different breathing disorders and can allow slow or fast inspiration and expiration."

Problems solved by technology

Hyperventilation may occur due to pulmonary edema or excess fluid built up in the lungs and may ultimately result in apnea episodes.
However, this treatment does not lead to an optimum therapy since excessive use of diuretics leads to renal complications and patient discomfort.
The method and apparatus do not provide a satisfactory treatment or central sleep apnea.
However, this device was not adapted for situations where patients would breath spontaneously.

Embodiment Construction

[0038]FIG. 1 illustrates a stimulator 20 comprising electrode assemblies 21, 22, each comprising a plurality of electrodes 21a-d and 22a-d respectively. The electrode assemblies 21, 22 are implanted in the diaphragm muscle so that one or more of electrodes 21a-d and to electrodes 22a-d are approximately adjacent to one or more junctions of the phrenic nerves 15, 16, respectively, with the diaphragm 18 muscle. The electrode assemblies 21, 22 sense and pace at the diaphragm muscle. They are implanted laparoscopically through the abdomen and into the muscle of the diaphragm 18 with needles or other similar devices. The electrode assemblies 21, 22 may be anchored with sutures, staples, or other anchoring mechanisms typically used with implantable EMG electrodes. The leads 23, 24 coupling the electrode assemblies 21, 22 to the control unit 100 are then routed subcutaneously to the side of the abdomen where a subcutaneous pocket is created for the control unit 100. The electrode assemblie...

Abstract

A device and method are provided for managing the treatment of a patient with respiratory disorders or symptoms. Respiratory parameters are sensed and recorded and communicated to an external device to provide information to a patient and / or provider for further treatment or diagnosis. Also respiratory disorders such as apnea or hypoventilation may be treated by electrically stimulating the diaphragm muscle or phrenic nerve in response to a sensed respiratory parameter or characteristic.

Description

FIELD OF THE INVENTION [0001] The invention relates to a device and method for detection, diagnosis and treatment of breathing insufficiencies or irregularities and to the management of pulmonary rhythm. Such irregularities may include, for example, hyperventilation, hypoventilation and apnea. The invention also relates to stimulating respiration in response to detecting hypoventilation or apnea. BACKGROUND OF THE INVENTION [0002] Breathing insufficiencies and irregularities may occur in conjunction with or as a result of a variety health related disorders and may further cause or exacerbate health disorders. Such breathing insufficiencies and irregularities may include, for example, hyperventilation, hypoventilation, apnea, and other related breathing disorders. Hyperventilation, which results in hyperoxia, is a condition in which the respiratory rate is pathologically high or is above a desired rate. Hyperventilation may occur due to pulmonary edema or excess fluid built up in the...
