摘要： Intracardiac lead for compliant fixation of a distal end of the lead to cardiac tissue. A fixation helix is disposed at the distal end of the lead. The fixation helix has a first end rigidly attached to the compliant fixation device and a second end that is sharpened to facilitate insertion of the fixation helix into cardiac tissue. The fixation helix can be designed to provide for either electrically active or inactive fixation. Once the lead is implanted in the cardiac tissue, the compliant fixation device, connecting the lead with the fixation helix, reduces the amount of lead movement that is transferred to the patient's tissue at the site of implantation of the fixation helix and reduces those forces from lead movement that could cause dislodgment of the fixation helix. The compliant fixation device thereby decreases the amount of irritation to the cardiac tissue, lessens the possibility of fibrous tissue growth around the area of the fixation helix, decreases the chance of dislodgment of the fixation helix, and reduces the possibility of perforation of the cardiac wall or tamponade of the pericardial sac.

摘要： The present invention is directed toward providing a composite lead body design for pacing and defibrillation leads. This lead body design improves the lead crush resistance in the lead segment that is implanted in the patient's clavicular region, while maintaining good fatigue resistance in the lead segment implanted in the heart. The clavicular segment has a generally flat profile. By flattening the clavicular segment proximal to the venous entry site, the lead will have a lower profile. Also, by substantially co-aligning the conductors within the clavicular segment, the crush resistance of the lead is significantly improved.

摘要： A defibrillation insulating device prevents current from directly shunting through the blood pool from the right ventricular defibrillation electrode to a superior vena cava electrode and vice versa. This forces current to flow through the heart muscle, thus increasing the current density throughout the heart, to depolarize the majority of the cardiac tissue with a minimum of energy.

摘要： A system is disclosed, for administering a therapeutic agent locally and to a depth within cardiac tissue. An elongate, flexible catheter contains a flexible electric conductor and supports at its distal end an implantable electrode incorporating a penetrating element, typically a fixation helix or a linear needle that penetrates cardiac tissue as the electrode is implanted. A therapeutic agent is delivered through the electrode, to the cardiac tissue surrounding the penetrating element. The electrode can act as a sensor, to monitor an electrical condition of the surrounding cardiac tissue, and to control delivery of the agent responsive to the sensed electrical condition. Several embodiments feature a distal reservoir adjacent the electrode for effecting transient deliveries of the therapeutic agent in minute quantities. Other embodiments are disclosed for providing sustained deliveries of the agents.

摘要： A system and method for delivering a drug to a target site within a patient's body. The system and method include a steerable guide catheter and a drug delivery catheter. The steerable guide catheter has a first extension tube and a second extension tube that are joined together and form a shoulder. The delivery catheter has a distal docking segment and a proximal docking segment. The guide catheter is inserted into the patient's body, then the delivery catheter is inserted into the guide catheter. The distal docking segment engages the first extension tube, the proximal docking segment engages the second extension tube, and the shoulder limits the distance the delivery catheter can be inserted into the guide catheter. Also, once the delivery catheter is inserted it can be rotated to attach the helical tip to the target site. The guide catheter also includes a steering mechanism as well as a friction mechanism which controls the tension on the steering mechanism. The delivery catheter also includes two luer fittings, each having its own lumen.

摘要： An implantable devices for the effective elimination of an arrhythmogenic site from the myocardium is presented. By inserting small biocompatible conductors and/or insulators into the heart tissue at the arrhythmogenic site, it is possible to effectively eliminate a portion of the tissue from the electric field and current paths within the heart. The device would act as an alternative to the standard techniques for the removal of tissue from the effective contribution to the hearts electrical action which require the destruction of tissue via energy transfer (RF, microwave, cryogenic, etc.). This device is a significant improvement in the state of the art in that it does not require tissue necrosis. In one preferred embodiment the device is a non conductive helix that is permanently implanted into the heart wall around the arrhythmogenic site. In variations on the embodiment, the structure is wholly or partially conductive, the structure is used as an implantable substrate for anti arrhythmic, inflammatory, or angiogenic pharmacological agents, and the structure is deliverable by a catheter with a disengaging stylet. In other preferred embodiments that may incorporate the same variations, the device is a straight or curved stake, or a group of such stakes that are inserted simultaneously.
