    • An implantable atrial defibrillator provides a pulse of defibrillating electrical energy to the atria of the heart in synchronism with sensed R waves in response to non-coincident sensing of an R wave at first and second areas of the heart. The defibrillating pulse is provided after a predetermined number of consecutive R waves are non-coincidently sensed to assure reliable synchronization. The atrial defibrillator is also operational in a marker mode wherein a number of synchronization marker pulses are delivered to the heart for detection on an externally generated electrocardiogram. The atrial fibrillation detector of the defibrillator is normally disabled and is activated when the sensed ventricular activity indicates a probability of atrial fibrillation to conserve a depletable power source. An endocardial lead is also described which ensures that the delivered atrial defibrillating electrical energy is substantially confined to the atria of the heart.

    • An assembly and method for effecting the condition of a mitral valve annulus of a heart includes a guide wire configured to be fed into the coronary sinus of the heart, and a mitral valve annulus therapy device configured to be slidingly received on the guide wire and advanced into the coronary sinus of the heart on the guide wire. A guide tube may further be employed for guiding the device into the coronary sinus. An introducer which may be employed for pushing the device into or pulling device out of the heart has a mechanism for releasably locking to the device. This enables substitution of the device if needed. Also, the crossover point of the circumflex artery and coronary sinus may be determined and avoided when the device is deployed.

    • A device and method facilitates the forming of a skin fold during deployment of a cannula. The device may be a disposable infusion device and the method comprises adhering, to a skin surface, a base member having a port for receiving a cannula, forming a skin fold having skin surfaces sloping away from opposite sides of the base member, driving a cannula through the port of the base member while maintaining the skin fold, and releasing the skin fold. To facilitate the forming of the skin fold, the device comprises a base having a base surface and a flexible layer member. The flexible layer member has a first surface adjacent the base surface and a second surface adapted to be adhered to a patient's skin. The first surface has a first portion adhered to a portion of the base surface and a second portion adherable to the base surface.
