摘要： An implantable medical device (10, 80, 90, 120, 130, 140, 150, 170, 180) includes a plurality of separately housed and flexibly interconnected modules (30, 32, 34, 172, 182). A first module (30) includes a control electronics within a first housing (36), and may be coupled to a second module (32) that includes a second housing (38) by a flexible interconnect member (44, 46, 174, 184). In some embodiments, an overmold (48, 82, 92, 122, 132, 176, 186), which may be flexible, at least partially encapsulates the first and second housings. The second module may be a power source module that includes a power source, such as a rechargeable battery, within the second housing. The implantable medical device may also include a third module, such as a recharge module that includes a coil within a third housing. The overmold may at lest partially encapsulate the third housing, or the third module may be tethered to the overmold by a flexible tether member (124). A flexible interconnect member and/or flexible overmold may allow multiples degrees of freedom of movement between modules of an implantable medical device.

摘要： An implantable medical device (IMD) including a nonhermetic battery is described. The IMD includes components and a power source module that includes the nonhermetic battery. The IMD also includes a barrier to substantially impede movement of substances from the nonhermetic battery to the components. The barrier may include a hermetic feedthrough, a gel, a polymer, or a solid electrolyte within the nonhermetic battery, and a seal member. The barrier may also be a material that encapsulates the nonhermetic battery and a getter within the IMD. In some embodiments, the IMD comprises a modular IMD including an interconnect member. In that case, the barrier may include a material that fills at least a portion of a void defined by the interconnect member. A length and a cross-sectional area of the interconnect member may also act as a barrier.

摘要： The invention is directed to techniques for decreasing the volume and thickness of a hermetic battery that includes an electrode stack contained within a hermetic housing. In particular, the invention is directed to batteries that have a non-uniform thickness as defined by the hermetic housing. A battery according to the invention includes a battery housing with at least two battery housing portions that define different thicknesses. For example, a first portion of the battery housing may have first thickness and house the battery, while a second portion of the battery housing has a second thickness and includes one or more feedthroughs. The second thickness may be greater than the first thickness.

摘要： Components (114, 116) of an implantable medical device (10) are arranged to facilitate a low-profile housing (36). A circuit board (80) within the housing carries integrated circuits (114) and discrete components (116). The integrated circuits and discrete components are located on first and second opposing surfaces (110, 112) of the circuit board, respectively. In some embodiments, the implantable medical device is implanted on a cranium of a patient and the housing is concave such that it substantially conforms to the cranium. In such embodiments, the integrated circuits and/or discrete components can be arranged on the circuit board according to height to better conform to the concavity of the housing. In some embodiments, the implantable medical device includes a telemetry coil (82) that is positioned within the housing such that it occupies space that cannot be practically occupied by the circuit board. The housing may comprise a feed through oriented at an angle relative to a major surface of the housing.

摘要： At least one surface (120,126) of an implantable medical device (10,90,100) is concave along at least one axis such that it substantially conforms to a surface within a patient, such as the cranium, when it is implanted on that surface. In some embodiments, the surface of the implantable medical device substantially conforms to an arc with a radius that is between 4.5 and 9.5 centimeters, and is preferably approximately equal to 7 centimeters. The implantable medical device comprises a plurality of interconnected modules (30,32,34), and an overmold (48,92,102) that at least partially encapsulates each of the modules. In such embodiments, at least one surface of the overmold is concave along at least one axis. Further, each of the modules of such an implantable medical device may comprise a housing (36,38,40), and at least one surface of at least one of the housings may be concave along at least one axis.
