    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 endocardial lead comprising an elongate body having a first defibrillation coil electrode, a second defibrillation coil electrode and a first pacing/sensing electrode. The first defibrillation coil electrode has a first end and a second end, where the first end is at or near the distal end of the elongate body and the second end spaced longitudinally from the distal end. The first pacing/sensing electrode is spaced longitudinally along the peripheral surface from the second end of the first defibrillation coil electrode. The second defibrillation coil electrode is spaced longitudinally along the peripheral surface from the first pacing/sensing electrode to afford positioning the first defibrillation coil longitudinally adjacent an apical location of the right ventricle of a heart with the first pacing/sensing electrode within the right ventricle of the heart and the second defibrillation coil within the right atrial chamber or a major vein leading to the right atrial chamber of the heart. The elongate body further includes a curved portion on which the first pacing/sensing electrode is positioned such that the first pacing/sensing electrode extends beyond the peripheral surface of the elongate body to engage the tissue of the heart. The first pacing/sensing electrode further includes a retaining element, where the retaining element is adapted to be embedded in the right ventricle of the heart to secure the first pacing/sensing electrode and the elongate body of the endocardial lead to the right ventricle of the heart.

    摘要: An implantable system for ambulatory monitoring of a high-risk heart failure patient includes a first pressure sensor implantable within an abdomen of the patient for sensing and generating an output representative of a baseline intra-abdominal pressure value of the patient and for chronically sensing and generating an output representative of an intra-abdominal pressure value of the patient at periodic intervals. At least one second implantable sensor is provided for sensing and generating an output representative of a second physiological parameter of the patient. Additionally, the system includes a processor for correlating the output of the first pressure sensor and the second physiologic sensor, and for comparing differences between the baseline intra-abdominal pressure value and subsequent intra-abdominal pressure values. The processor can reside in another implantable device or in an external device/system.

    摘要: A data logging system and method in which an implantable medical device transmits logged data to an external data logging device with low energy potential signals. The implantable device generates potential signals modulated with digitally encoded data by operating a current source to cause corresponding electrical potentials that can be sensed at the skin surface by the external data logging device. The data logging device then demodulates the sensed potentials to derive the digital data and stores the data in a data logging storage medium.

The cardiac device may be, for example, an implantable cardioverter/defibrillator, cardiac pacemaker, or combination device that communicates via a radio frequency link with a drug delivery device. The drug delivery device is preferably an electrically modulated transdermal drug delivery device for delivering the drug transdermally in accordance with a signal received from the cardiac device.
