    摘要： An apparatus for and method of measuring pressure through a septum in a patient's heart is disclosed. A lead inserted into the right side of a heart is routed through the septum to gain access to the left side of the heart. The lead includes an attachment structure that secures the lead to one or both of the septal walls. The attachment structure may include at least one protruding tine, membrane, inflatable balloon, involuted spiral or J-lead that engage one or more sides of the septum. The lead also includes one or more sensors for measuring cardiac pressure on the left side of the heart and, as necessary, the right side of the heart.

    摘要： A body fluid pressure sensor module according to the invention comprises a housing having a first end and a second end and enclosing a pressure sensor. The pressure sensor is electrically coupled to a plurality of electrical conductors extending into the housing through a feedthrough disposed within, and hermetically sealing, the first end of the housing. The housing defines a chamber disposed between the feedthrough and the second end of the housing. The chamber contains a material in communication with the pressure sensor, the material being capable of transmitting pressure variations to the pressure sensor. The plurality of electrical conductors have ends within the housing, and the pressure sensor is mounted on the end of at least one of the conductors. Also disclosed are medical leads incorporating the pressure sensor module, and methods for fabricating the modules. The pressure sensor module is compact, and particularly so where cable conductors are utilized and the sensor is directly mounted on at least one of the cable conductors. The compactness of a pressure sensor module pursuant to the invention facilitates its incorporation into a small diameter, flexible medical lead enhancing its placement within a patient's body, for example, within the left atrium of the heart.

    摘要： Tachyarrhythmia is treated by applying anti-tachycardia pacing through at least one multi-site electrode set located on, in or around the heart. The electrode set is arranged and located such that an electrical activation pattern having a wave-front between substantially flat and concave is generated through a reentrant circuit associated with the tachyarrhythmia. The electrode set may be one of a plurality of predefined, multi-site electrode sets located on, in or around the atria. Alternatively, the electrode set may be formed using at least two selectable electrodes located on, in or around the atria.
