    摘要: Disclosed is a cytostatic drug attached to a sterile sheet that is designed to be placed between internal body tissues to prevent the formation of post-operative adhesions, which adhesions are really scar tissue formation. This sheet onto or into which the drug is placed may be either a permanent implant or it may be biodegradable. By impregnating an existing product such as the Johnson & Johnson SURGICEL™ absorbable hemostat gauze-like sheet with an anti-proliferative drug such as sirolimus, the biodegradable, drug impregnated mesh would act as a barrier to cell proliferation and hence be a deterrent to the formation of adhesions or scar tissue. Another embodiment of this invention is a cytostatic drug attached to a sheet that is placed at the site of an anastomosis to decrease scar tissue formation from within the vessel at the site of the anastomosis.

    摘要: Disclosed is a “tracker system” that includes implanted electrical leads which are part of an implanted cardiotracker plus external equipment that includes external alarm means and a physician's programmer. The tracker system is designed to monitor the degradation of a patient's cardiovascular condition from one or more causes. These causes include the rejection of a transplanted heart and/or the progression of a stenosis in a coronary artery. As one or more stenoses in a coronary artery become progressively more narrow thereby causing reduced blood flow to the heart muscle coronary circulation, the tracker system can alert the patient by either or both internal and/or external alarm means to take the appropriate medical action. The physician's programmer can be used to display histograms of key heart signal parameters that are indicative of the patient's cardiovascular condition.

    摘要: The present invention is a stent delivery system that uses short section of guidewire fixedly attached to the distal section of a balloon angioplasty catheter onto which a stent is co-axially mounted. By not having a guidewire that slides through the balloon of the balloon angioplasty catheter, the deflated balloon on which the stent is mounted can have a reduced diameter. Therefore, the outer diameter of the pre-deployed stent mounted onto that balloon is also minimized. This provides a smaller profile, i.e., a smaller outer diameter, for the stent. The time to perform a stent delivery procedure is reduced; a separate guidewire does not have to be placed prior to using the stent delivery system to place the stent at the site of a stenosis. Another embodiment of the present invention has a core wire that extends for nearly the entire length of the stent delivery system, the guidewire having different levels of stiffness for different portions of the core wire's length.

    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. 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 also provided by an audio alarm or an electrical tickle within the human body indicating that a myocardial infarction has been detected. An externally located part of the system, in the form of a patient operated initiator, can be used to trigger the release of medication as soon as a first sign of a stroke has been detected in order to prevent damage to brain tissue that would be caused by that stroke. Thus the system can be used to prevent trissue damage from either a myocardial infarction or a stroke. 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 a myocardial infarction or a stroke.

    摘要: Disclosed is a multiple electrode, closed-loop, responsive system for the treatment of certain neurological diseases such as epilepsy, migraine headaches and Parkinson's disease. Brain electrodes would be placed in close proximity to the brain or deep within brain tissue. When a neurological event such as the onset of an epileptic seizure occurs, EEG signals from the electrodes are processed by signal conditioning means in a control module that can be placed beneath the patient's scalp, within the patient's chest, or situated externally on the patient. Neurological event detection means in the control module will then cause a response to be generated for stopping the neurological event. The response could be an electrical signal to brain electrodes or to electrodes located remotely in the patient's body. The response could also be the release of medication or the application of a sensory input such as sound, light or mechanical vibration or electrical stimulation of the skin. The response to the neurological event can originate from devices either internal or external to the patient. The system also has the capability for multi-channel recording of EEG related signals that occur both before and after the detection of a neurological event. Programmability of many different operating parameters of the system by means of external equipment provides adaptability for treating patients who manifest different symptoms and who respond differently to the response generated by the system.
