    摘要: Disclosed are methods for detecting an acute myocardial infarction (i.e., a heart attack) at the earliest possible time and promptly warning the patient that he should immediately seek medical care. The present invention includes an implantable electronic system that can sense a change in the patient's electrogram that is indicative of a heart attack. If a heart attack is sensed, the device would then cause an implantable and/or externally located alarm to be actuated to warn the patient of his condition and a medical practitioner at a remote diagnostic center would receive the patient's electrogram for analysis. The patient or a caretaker would then be informed to self-inject medication through a subcutaneous, pass-through drug port that can be a separate device or integrated into the implanted device that is designed for the early detection of a heart attack. The methods of the present invention include determining if a human patient is likely to have a heart attack and, if he is, then implanting within that patient a device that can sense when a heart attack occurs and alarm the patient to take appropriate actions if a heart attack does occur.

    摘要: Disclosed is a system for the detection of cardiac events that includes an implanted device called a cardiosaver, a physician's programmer and an external alarm system. The system is designed to provide early detection of cardiac events such as acute myocardial infarction or exercise induced myocardial ischemia caused by an increased heart rate or exertion. The system can also alert the patient with a less urgent alarm if a heart arrhythmia is detected. Using different algorithms, the cardiosaver can detect a change in the patient's electrogram that is indicative of a cardiac event within five minutes after it occurs and then automatically warn the patient that the event is occurring. To provide this warning, the system includes an internal alarm sub-system (internal alarm means) within the cardiosaver and/or an external alarm system (external alarm means) which are activated after the ST segment of the electrogram exceeds a preset threshold.

    摘要: A method for implanting a balloon expandable stent at a site within a passageway of a curved coronary article. The stent includes at least two longitudinally spaced apart circumferential rings. At least one longitudinally extending connector extends between adjacent rings. The connector has at least one turn back portion that can expand or contract in length while being passed through a curved passageway. The stent is disposed on a stent delivery catheter having an inflatable balloon. The stent delivery catheter and the stent is delivered through the passageway to the site of implementation with the connector member expanding or contracting in length to facilitate delivery and placement of the stent. The stent is expanded at the site of implantation by inflating the balloon to force the stent radially outward against the wall of the coronary artery.

    摘要: Disclosed is a system and method for treating headaches. The system employs a self-contained, battery operated, readily portable and easy-to-operate head-mounted magnetic depolarizer to generate a transient or time-varying high-intensity magnetic field into and around the user's head or neck. The magnetic depolarizer system can be used to depolarize the neurons of the brain and/or the trigeminal nerve. This type of neuronal depolarization has the capability for terminating migraine or other types of headaches.

    摘要: Disclosed is a means and method for placing an implantable neurostimulator control module into a place in the cranium where cranial bone has been removed. The method for accomplishing this cranial implantation is by first removing a patient's hair over the site of the implant, then cutting the scalp at that site and pulling it back to expose the cranium. A neurosurgeon would then remove a portion of the cranial bone to accept a control module to be implanted within that hole. The control module would then be placed into that hole. It is also conceived that the control module would be fixed in place by the use of one or more attachment devices such as a multiplicity of bone screws placed through holes in one or more flanges that extend over the cranium beyond the control module. The implantation could also include a fairing placed around the control module to provide a smooth contour under the patient's scalp. Also described is a spacer shim placed under the flange(s) to adjust the position of the control module so that its bottom surface does not put pressure on the dura mater lying directly over the brain tissue at the bottom of the hole. It is also envisioned that a resorbable disk could be placed under the bottom surface of the control module to further protect the brain and/or to elute an anti-biotic or anti-inflammatory substance to reduce the possibility of infection and/or inflammation.

    摘要: Disclosed is a completely implantable system that can detect the occurrence of a myocardial infarction, i.e., a heart attack, and automatically inject a thrombolytic and/or anti-thrombogenic agent into the bloodstream to promptly dissolve the thrombus that caused the myocardial infarction and prevent the formation of additional thrombi. It is well known that a myocardial infarction can be detected from a patient's electrocardiogram by noting an ST segment voltage deviation as compared to the voltage of the patient's TP or PQ segments. Upon detection of a myocardial infarction, an ST segment deviation electronic detection circuit within the implanted device can produce an output signal that can cause a thrombolytic and/or anti-thrombogenic agent contained within an implanted, pressurized reservoir to immediately and automatically release medications into the patient's bloodstream. A patient warning system is provided by an audio alarm or an electrical tickle within the human body indicating that a myocardial infarction has been detected. The implanted system can also send a radio message to an externally located receiver that automatically dials an emergency rescue team to take the patient to a hospital for continuing treatment of his myocardial infarction. An implantable defibrillator or pacemaker that includes the capability for informing the patient that myocardial infarction has been detected is also disclosed. Still further, this invention could also be used without a defibrillator or pacemaker but as an implanted system (without medications) whose only function would be the detection and warning of myocardial infarction at the earliest possible time.

    摘要: Disclosed herein is a multiple electrode, closed-loop system for the treatment of certain neurological disorders such as epilepsy, migraine headaches and Parkinson's disease. Specifically, the present invention combines a multi-electrode array with sophisticated signal processing techniques to achieve reliable detection of the onset of a neurological event (such as an epileptic seizure or migraine headache) typically originating from a focus of limited spatial extent within the brain. It is highly desirable to detect an epileptic seizure at least 5 seconds before the onset of clinical symptoms. Since there is often a d-c shift in the EEG voltage more than 5 seconds before the seizure, disclosed herein is a means for utilizing the d-c shift of the EEG for early detection of the seizure.
