摘要： Disclosed is an ostial stent positioner that has the form of a wire for most of its length and having a short cylinder with expandable legs situated at the positioner's distal end. The cylinder with its attached wire acts as an introducer sheath to introduce a stent delivery system with a stent into the artery that is to be stented. A second aspect of the present invention is a method for accurately placing a stent at the ostium of an artery that would have an ostial stenosis. Examples of such arteries that have ostial stenoses are the right and left main coronary arteries, a saphenous vein graft as used in coronary bypass surgery and the renal arteries. Also disclosed are designs for the short cylinder that have a variable diameter so as to fit snugly within guiding catheters having different inside diameters.

摘要： Disclosed is an ostial stent positioner that has the form of a wire for most of its length and having a short cylinder with a longitudinal slit and expandable legs situated at the positioner's distal end. The slit cylinder with its attached wire acts as an introducer sheath to introduce a stent delivery system with a stent into the artery that is to be stented. A second aspect of the present invention is a method for accurately placing a stent at the ostium of an artery that would have an ostial stenosis. Examples of such arteries that have ostial stenoses are the right and left main coronary arteries, a saphenous vein graft as used in coronary bypass surgery and the renal arteries. Also disclosed are designs for the slit cylinder that provides a variable diameter so as to fit snugly within guiding catheters having different inside diameters.

摘要： Disclosed is a system for the detection of cardiac events (a guardian system) 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 one or more detection 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 guardian system includes an internal alarm sub-system (internal alarm means) within the cardiosaver and/or an external alarm system (external alarm means). If the guardian system is put into a pacemaker, the algorithm can utilize a different analysis of the electrogram depending on whether or not the pacemaker is actually pacing the heart.

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.
摘要翻译：薄壁导丝管固定并密封地附接到球囊血管成形术导管的近端部分和远端部分。支架同轴地安装在球囊血管成形术导管的可充气球囊上。由于导丝管形成球囊血管成形术导管的内衬，导管的流体膨胀腔被密封，使得气囊加压的充气液体将不会像没有“内衬”那样泄漏，气球血管成形术导管附着于导丝本身。通过不具有传统导丝通过其传播的传统内轴，其上安装有支架的放气气球可以具有减小的直径。

摘要： The present invention is a system that utilizes optimized high pass or band pass filtering to provide accurate detection of changes in the ST segment of an electrogram as detected by an implanted cardiosaver system, which ST segment changes are indicative of coronary ischemia. To accurately detect changes in the ST segment of the electrogram, the cardiosaver system uses either analog or digital high pass filtering having an electrogram voltage reduction of 6 dB at some frequency between 0.05 Hz and 1.0 Hz with less than 6 dB of attenuation at frequencies above 1.0 Hz. and more than 6 dB of attenuation for frequencies below 0.05 Hz. The optimized filter would include attenuation of electric power generation frequencies of either 50 Hz or 60 Hz to reduce electromagnetic interference. The system also includes both implanted and external portions that provide a patient alarm if coronary ischemia is sensed.

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.
