    摘要: A delivery system and method for delivering a right ventricular lead into a right ventricle includes a delivery device having an inflatable balloon at a distal end. The device is inserted into the venous system, the balloon is inflated and the device is floated along a blood flow path within the venous system through the heart and into the pulmonary artery. The lead is delivered into the right ventricle using the device. In one embodiment, the device is a catheter that facilitates placement of a guide wire into the right ventricle for delivery of the lead. The catheter is then removed and the lead is inserted into the right ventricle over the guide wire.

    摘要: Implantable cardiac monitoring and stimulation methods and devices with epicardial leads having sensor feedback. A fixed or extendable/retractable sensor may be displaceable within the lead's lumen and configured to sense the presence of an anatomical feature or physiological parameter of cardiac tissue in proximity with the lead body's distal end. The sensor may include an ultrasonic sensing element, a perfusion sensor, a photoplethysmographic sensor, or a blood oximetry sensor. Methods of determining suitability for implanting a lead involve the steps of accessing an epicardial surface of the heart, and moving the cardiac lead to an implant site at the epicardial surface. A transmitted signal is directed at the implant site. A reflected signal is received, indicative of the presence of a blood vessel at the implant site. A determination may be made to determine whether the implant site is suitable or unsuitable based on the reflected signal.

    摘要: A system and method for navigating coronary vasculature involves use of a guide catheter system which includes a guide catheter, a navigator catheter longitudinally displaceable within the guide catheter, and a deflection arrangement provided at a distal end of the navigator catheter. The guide catheter is advanced to at least a patient's coronary sinus ostium, and the navigator catheter is extended from the guide catheter to a location proximate or within an angled vein distal to the coronary sinus ostium. Using the deflection arrangement, a guide wire passing through the navigation catheter is directed into the angled vein. A lead having an open lumen is advanced over the guide wire to direct the lead to an implant site within the angled vein.

    摘要: A lead for sensing and pacing a left ventricle of the heart includes a lead body having a proximal portion and a distal portion, a lumen extending through the lead body, a conductor extending through the lead body from the proximal end to the distal end and an electrode disposed on the distal portion of the lead body and electrically coupled to the conductor. A distal tip of the lead body is continuously deflectable upon advancement and withdrawal of a stylet through the lumen at the distal portion to access a selected branch of the coronary sinus. The distal tip of the lead body may be offset before or after continuously deflecting the distal tip.

In addition, cardiac signals are sensed and pacing pulse vectors are delivered between different combinations of the first and second left ventricular electrode, the first supraventricular electrode and a conductive housing. In an additional embodiment, a first right ventricular electrode is used to sense cardiac signals and provide pacing pulses with different combinations of the first and second left ventricular electrodes, the first supraventricular electrode and the housing.

    摘要: A guiding catheter for use in medical procedures includes a flexible shaft with one or more audio transducers and a distal tip. An audio signal may be sent to one or more of the transducers and a reflected signal is received at one or more transducers. The reflected signal is used to detect the presence of an anatomical structure to assist in navigating the catheter to its destination. In another arrangement, the transducer can be used passively to detect physical characteristics of the heart such as sound, subsonic energy or temperature, that indicate relative proximity of a destination vessel.

    摘要: A method of manipulating a catheter assembly involves providing an inner catheter member movably disposed within an outer catheter member. At least a distal end portion of the inner catheter member has a stiffness greater than that of at least a distal end portion of the outer catheter member. The distal end portion of the outer catheter member includes a deflectable distal end. The method further involves advancing the inner catheter member through the outer catheter member toward the deflectable distal end of the outer catheter member, and longitudinally displacing the distal end portion of the inner catheter member relative to the deflectable distal end of the outer catheter member to alter a shape of the deflectable distal end.
