A method, system and device for implanting an electrode assembly of an implantable medical device in a patient's heart. Positioning one or more radiopaque markers in a coronary sinus of the patient's heart. Positioning, by using the one or more positioned radiopaque markers as a fluoroscopic visual reference, a distal tip of a delivery catheter within a right atrium of the patient's heart so that a distal opening of a lumen of the catheter is against a septal wall of the heart at a location between the ostium of the coronary sinus and the A-V nodal area of the right atrium, and so that the tip of the catheter is generally directed toward a left ventricle of the patient's heart. Advancing the electrode assembly through the lumen of the catheter and into the septal wall.

Implantable medical electrode assemblies, devices, systems, kits, and methods

VfA cardiac therapy uses an implantable medical device or system. The implantable medical device includes a tissue-piercing electrode implanted in the basal and/or septal region of the left ventricular myocardium of the patient's heart from the triangle of Koch region of the right atrium through the right atrial endocardium and central fibrous body. The device may include a right atrial electrode, a right atrial motion detector, or both. The device may be implanted completely within the patient's heart or may use one or more leads to implant electrodes in the patient's heart. The device may be used to provide cardiac therapy, including single or multiple chamber pacing, atrioventricular synchronous pacing, asynchronous pacing, triggered pacing, cardiac resynchronization pacing, or tachycardia-related therapy. A separate medical device may be used to provide some functionality for cardiac therapy, such as sensing, pacing, or shock therapy.

VfA cardiac resynchronization therapy

AV synchronous VfA cardiac therapy

In some examples, an implantable medical device (IMD) that includes a pulse generator comprising a housing, electrodes, and circuitry configured to deliver cardiac pacing via the electrodes. The IMD may further include a lead including at least one of the electrodes, an elongate body, a fixation helix, and a connector segment. A width of the helix transverse to a longitudinal axis of the lead is greatest at a distal end of the helix. A proximal end of the elongate body may be connected to a distal end of the pulse generator, and the helix may be attached to a distal end of the elongate body. The pulse generator may include a first connector tab. A distal end of the connector segment may be configured to receive the proximal end of the elongate body and a proximal end of the connector segment may include at least one second connector member configured to engage the first connector tab.

Leaded electrical stimulation system

VFA cardiac resynchronization therapy

A method and system for employing a medical device is disclosed. The medical device includes a housing, a processor disposed within the housing, a connector module, and a medical electrical epicardial lead connected to the processor through the connector module. The epicardial lead is used to sense a cardiac signal from tissue of a patient. The lead comprises an insulative lead body that includes a proximal end and a distal end, at least one conductor disposed in the lead body, and a side helical fixation member, disposed a distance from the distal end, the side helical fixation member. The side helical fixation member comprises a set of windings configured to wrap around the lead body circumference. The side helical fixation member includes a distal tip comprising a sharpened elongated flat free end that is perpendicular to the lead body and angled toward an inside of the set of windings.

Epicardial defibrilation lead with side helix fixation and placement thereof

Temporary touch-proof connectors are disclosed that include an insulating body defining a passageway having an open leading end configured to receive a connector element of a medical lead and an enclosed trailing end shielding the connector element.

Temporary touch-proof connector for heartwires

The present invention provides a pacing system with a lead having a fixation element for providing stable fixation relative to the junction of the left and right brachiocephalic veins of the patient. In a first embodiment, a short tine element is provided for engaging the brachiocephalic junction. The present invention also provides a pacing system with a lead having a fixation element for providing stable fixation relative to the atrium and the SVC of the patient. In another embodiment, a three-pronged tine is provided for engaging the portion of the atrium adjacent the SVC.

Pacing leads having a brachiocephalic tine or star tine

The present invention provides a pacing system with a lead having a fixation element for providing stable fixation relative to the patient's SVC, preferably providing for positioning of the atrial electrodes near the sinus node. In a first embodiment, an adjustable loop is provided for engaging the inside wall of the SVC so as to obtain fixation of the lead just above the sinus node. Other embodiments utilize tine arrangements for providing the fixation relative to the SVC.

Perpendicular atrial fixation/stimulation loop

The present invention provides a cardiac pacing system with a DDD lead with pre-stressed curvilinear portions, the lead being able to adapt to heart movement and size so as to provide more stable positioning with respect to the atrium. The lead has at least three such pre-stressed curvilinear portions positioned to adapt to the patient's heart and to absorb movement due to contractions so as to maintain atrial electrodes in a stable position with respect to the atrial wall.

Flexible and adjustable DDD lead
