摘要： An improved medical lead assembly and method of use is provided. The lead assembly includes a lead body, and a spring member positioned adjacent to the lead body. The spring member may be deployed a selectable amount to maintain the lead body in a fixed location within a patient's body. The spring member may be an expandable coil, a mesh structure that is similar to a stent, or any other similar device that may be positioned in a low-profile state during a lead implant procedure. After the lead is positioned at a target destination, the spring member may be deployed an amount that is selected based on the characteristics of the surrounding tissue, including vessel size. According to one aspect of the invention, the lead assembly may provide means for facilitating chronic lead extraction.

摘要： A transvenous lead specifically designed for multi-chamber electrical stimulation or sensing. In a first embodiment the lead features one or more electrodes for communication with the right atrium as well as one or more electrodes for communication with either or both of the left chambers of the heart. The lead further features structures to simultaneously bring the first electrode into contact with a first chamber, such as the right atrial wall and the second electrode into contact with a particular portion of the coronary sinus wall, to electrically access the left atrium or ventricle. In the preferred embodiment the lead body has varying flex or stiffness characteristics along its length between each of the electrodes. The relation of the varying flex or stiffness characteristics along the lead body length as well as the various linear placements of the electrodes along the lead body length function to simultaneously bring the first electrode into contact with a first desired portion of the heart, such as the right atrial wall, and the second electrode into contact with a second desired portion of the heart, such as a portion of the coronary sinus wall.

摘要： The present invention provides a method and apparatus for assessing ventricular function on a chronic basis using a plurality of electrodes disposed on or about a left ventricle and/or a right ventricle—and optionally, at least one mechanical or metabolic sensor—all operatively electrically coupled to an implantable medical device. The plurality of electrodes are preferably spaced-apart so that at least one electrode is disposed electrical communication with a discrete volume of ventricular tissue. In one embodiment, the discrete volume of tissue is defined by multiple longitudinal and axial planes as known and used in the medical arts. Thus, according to the present invention, at least one electrode couples to appropriate sensing circuitry and essentially provides a localized electrogram (EGM) that, when compared to other EGMs, provides for configurable, localized delivery of therapeutic pacing stimulus, diverse impedance-sensing vectors, various diagnostic information regarding myocardial function and/or anti-tachycardia pacing.

摘要： A lead stabilization and extension wire that enables the withdrawal of a guide catheter over an electrical medical lead body without dislodging an electrode or sensor from an implantation site or detaching the fixation mechanism and methods of use and a kit are disclosed. The lead stabilizer and retraction wire comprises a wire sheath and an elongated core wire insertable within a sheath lumen. The sheath is insertable within a lead body lumen and includes a movable lead clamp that can engage with a lead connector element and a friction element frictionally engaging the core wire to maintain the extension wire length. The lead stabilizer and retraction wire is insertable into the lead body lumen enabling retraction of the guide catheter over the lead stabilization and extension wire while force is applied through the lead stabilization and extension wire to maintain the distal electrode at the implantation site.

The flexible anode has a length less than approximately 10 millimeters and is spaced apart from and proximal to the first pacing cathode and spaced apart from and distal to the second pacing cathode. The spacing between the anode and the first pacing cathode is approximately equal to the spacing between the anode and the second pacing cathode.
