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： A thin-walled guide wire tube is fixedly and sealably attached to both a proximal section and a distal section of a balloon angioplasty catheter. A stent is co-axially mounted onto the inflatable balloon of the balloon angioplasty catheter. Because the guide wire tube forms an inner liner for the balloon angioplasty catheter, the fluid inflation lumen of the catheter is sealed so the inflation liquid that pressurizes the balloon will not leak as it would be if there were no “inner liner” and the balloon angioplasty catheter were attached to the guide wire itself. By not having a traditional inner shaft through which a conventional guide wire slides, the deflated balloon on which the stent is mounted can have a reduced diameter.

摘要： This invention is an anti-proliferative drug placed onto or within a sterile sheet or mesh 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 mesh or gauze 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 Rapamycin or Taxol, the biodegradable, drug impregnated mesh would act as a barrier to cell proliferation and hence be a deterrent to the formation of adhesions. Another embodiment of this invention is an anti-proliferative drug attached to a bandage that is placed onto a cut in the skin to decrease scar tissue formation. Still another embodiment of the invention is an anti-proliferative drug that is attached to a surgical suture or coated onto a surgical staple both of which are used for connecting human tissues. The suture or staple then being more capable for decreasing cellular proliferation where the suture or staple material passes through the human tissue.

摘要： A thin-walled introducer sheath is described. In some embodiments, the introducer sheath includes structural support components, such as wires, used in connection with a polymeric inner coating, a polymeric outer coating, or both. Further, in some embodiments, the wire components are annealed to reduce cold-work-related stresses and hardness. Use of annealed components may enable a reduction in the thickness of the polymeric outer coating in some applications.

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 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.
