    摘要: An implantable cardiac system has a master pacing unit and a remote satellite pacing unit. The master pacing unit is electrically coupled to a right side of a patient's heart via a lead assembly. The satellite pacing unit is a leadless device mounted on the left side of the patient's heart and is wirelessly controlled by the master pacing unit. The satellite pacing unit is affixed to the heart by one or more mounting members. The base of the satellite unit case has a gel-like material which facilitates adhesion of the pacing unit to the heart tissue. The gel-like material promotes tissue growth to hold the pacing unit in place on the heart. The gel-like material may be composed of polyvinlpyrrolidone and may contain a steroid, such as dimethyl sulfoxide (DMSO), or dexamethazone sodium phosphate.

    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: The intrapericardial lead includes a lead body having a proximal portion and a flexible, pre-curved distal end portion. The distal end portion carries at least one electrode assembly containing an electrode adapted to engage pericardial tissue. The distal end portion further carries a pre-curved flexible wire member having ends attached to spaced apart points along the distal end portion of the lead body, the flexible wire member having a normally expanded state wherein an intermediate portion of the wire member is spaced apart from the distal end portion, and a generally straightened state wherein the wire member and the distal end portion are disposed in a more parallel, adjacent relationship so as to present a small frontal area to facilitate delivery into the pericardial space. The wire member re-expands to its normal state after delivery into the pericardial space to anchor the distal end portion of the lead body relative to the pericardial tissue.
