    摘要: The system of the preferred embodiments includes a first rotational element, a second rotational element, and a therapeutic source coupled to the rotational elements. The system permits simultaneous attachment to and movement around a surface of tissue, preferably during an ablation procedure (either during lesion creation or between lesion creation events), or during any other suitable procedure. The therapeutic source functions to translate along the path of tissue and deliver therapy as the first and second rotational elements rotate and roll along the path of tissue. The therapeutic source preferably delivers contiguous doses of therapy along the path of tissue. The system is preferably designed for delivering therapy to tissue and, more specifically, for delivering therapy to cardiac tissue. The system, however, may be alternatively used in any suitable environment and for any suitable reason.

    摘要: A medical device, and related method, use epicardial ablators and detectors for intraoperative epicardial approaches to ablation therapy of cardiac conduction pathways. An epicardial gripper is sized to grasp the cardiac circumference or smaller structures on the epicardial surface of the heart. Ablators are disposed on the arms of the gripper for epicardial ablation of cardiac conduction tissue. In another embodiment of the invention, an electrode system includes a flexible, adjustable probe forming a loop for epicardial ablation. Ablators are provided on one or multiple surfaces of the probe for epicardial ablation of cardiac conduction tissue. In yet another embodiment of the invention, an endocardial ablator detection system provides an indicator adjacent an ablator on an endocardial catheter, and a detector on an epicardial probe. The epicardial probe detects signals transmitted by the indicator on the endocardial catheter to localize the position of the endocardial ablator relative to the epicardial surface. The surgeon uses this information for guidance in adjusting the position of the endocardial ablator according to therapeutic objectives of cardiac ablation.

    摘要: The invention is a flexible plate, suitable for use as a flexographic printing plate, comprising a flexible substrate primed with an aziridine functional material, and, contacting a primed surface of said substrate, a photosensitive layer which comprises a substantially polar acrylate compound, an elastomeric block copolymer, and a photoinitiator. The adhesion between the substrate and the photosensitive layer is strengthened by use of the aziridine functional primer in combination with a substantially polar acrylate compound. In contrast, when acrylate compounds with large nonpolar portions are used, the adhesion tends to be poor. The adhesion is further improved by exposure of the plate to radiation.

    摘要: Techniques for discrimination of heart rhythms in cardiac rhythm management devices include determining a current covariance matrix of multiple electrograms measuring each current heart beat, determining a distance measure between the current covariance matrix and a predetermined covariance matrix of the multiple electrograms measuring at least one different heart beat; and determining whether the heart beat represents ventricular tachycardia based on the distance measure.

    摘要: A method and system for lysing a patient's heart tissue causing or involved with arrhythmia which includes an intravascular catheter with a relatively inelastic occlusion balloon on the distal end of the catheter which is inflated to block an artery or vein of the patient's heart so than when lysing fluid such as an ethanol solution is discharged from the distal port in the catheter the inflated balloon prevents the proximal refluxing of lysing medium into undesirable areas of the patient's heart. The inelastic balloon is configured to be inflated to a diameter of about 0.7 to about 1.3, preferably about 0.8 to about 1.2, times the diameter of the blood vessel in which the balloon is to be inflated so as to effectively occlude the passageway without damaging the wall of the blood vessel. The working length of the balloon is less than about 1.5 cm, preferably less than 0.75 cm.
