摘要： A method for allowing cardiac signals to be sensed and pacing pulse vectors to be delivered between two or more electrodes. In one embodiment, cardiac signals are sensed and pacing pulse vectors are delivered between least one of a first left ventricular electrode and a second left ventricular electrode. Alternatively, cardiac signals are sensed and pacing pulse vectors are delivered between different combinations of the first and second left ventricular electrodes and a first supraventricular electrode. 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： Methods facilitate inserting a cardiac lead into a patient's vasculature. A cardiac lead system includes a cardiac lead having a lumen, and a guide member displaceable within the lumen. The guide member includes a guide wire extension that extends distal to the elongated body of the guide member. The guide wire extension is dimensioned to pass through an external distal opening of the cardiac lead lumen. Engagement of stop features or a stop mechanism of the cardiac lead system provides a push point for advancing the cardiac lead system through the patient's anatomy.

摘要： A cardiac rhythm management system includes a lead assembly for intracardiac mapping, pacing, and drug delivery. The lead assembly includes an implantable endocardial lead having a proximal end for connection to an implantable cardiac rhythm management device and a distal end for disposal in an intracardiac region. The lead includes a pacing-sensing electrode and a drug delivery device, both located at or near the distal end. A lumen is within and extends throughout the lead, with an opening at or near the proximal end and another opening at or near the distal end. The lumen provides for access to the intracardiac region by a steerable stylet and a hollow needle, one at a time. The steerable stylet allows for electrophysiological mapping of the intracardiac region. The hollow needle allows for delivery of chemical, biochemical, and/or biological substance to the intracardiac region.

摘要： A seal adapted for use with medical devices is provided with a lead having a distal tip electrode. The distal tip of the lead is adapted for implantation on or about the heart and for connection to a system for monitoring or stimulating cardiac activity. The lead can include a fixation helix for securing the electrode to cardiac tissue. The lead assembly can alternatively include an open lumen lead tip. A seal is provided within the lead tip assembly such that the seal is expanded to prevent or limit further entry of fluids through the lead tip. The seal includes an expandable matrix, such as a hydrogel. The seal is formed on or within the lead when the lead and the seal comes into contact with a fluid and expands. The seal is also formed as a plug which is deployed through the medical device, and expands as the plug absorbs fluid. A housing incorporating the seal can also be attached to a portion of the medical device to provide the seal.

摘要： An improved guidewire for assisting in implantation of a cardiac lead includes three sections. The most distal zone is sufficiently floppy to prevent trauma to the vessel walls through which the guidewire and lead are inserted. An intermediate zone is generally stiffer and has a cross-section less than or equal to the cross-section of the distal zone. The third zone is stiffer yet and is joined to the intermediate zone by a shoulder. The shoulder cooperates with protrusions on the lead to transfer forces between the guidewire and lead. A finishing wire having temporary locking means to lock the finishing wire to the lead is employed to remove the guide catheter without moving the lead from its desired location. Lubricious coatings are also provided to reduce friction between the lead and guidewire.

摘要： A catheter assembly for cannulating a heart vessel includes a guide handle having proximal and distal ends, a lumen open at least at the distal end of the guide handle, and a stop member disposed within the lumen at a distal end of the guide handle. A catheter of the assembly has a proximal end disposed within the lumen of the guide handle and a preformed distal end. The catheter is longitudinally displaceable within the guide handle to adjust an exposed length of the distal end of the catheter. The stop member is engagable with the proximal end of the catheter to prevent the proximal end of the catheter from passing out of the guide handle. A locking mechanism within the guide handle to selectably prevents and permit axial rotation between the guide handle and catheter while permitting longitudinal displacement of the catheter within the guide handle.
摘要翻译：用于插入心脏血管的导管组件包括具有近端和远端的引导手柄，至少在引导手柄的远端处开口的内腔，以及设置在引导手柄的远端处的内腔内的止动构件。组件的导管具有设置在引导手柄的内腔内的近端和预成型的远端。导管可以在引导手柄内纵向移位，以调整导管远端的暴露长度。止动构件可与导管的近端接合，以防止导管的近端从引导手柄传出。引导手柄内的锁定机构可选择地防止和允许引导手柄和导管之间的轴向旋转，同时允许导管在引导手柄内的纵向移位。
