An implantable electronic device has a main housing with a leak-proof-sealed housing chamber containing electronic circuitry. An optical module is connected to the main housing, and has a module housing with a leak-proof-sealed transducer chamber isolated from the main housing chamber. The module housing has an optically-transmissive optical element, and the transducer chamber contains an optical transducer connected to the circuitry. The module housing includes a number of signal conductors extending from the transducer chamber to a location external to the transducer chamber, and connected to circuitry in the main housing chamber.

An implantable medical device having a sealed housing forming a chamber containing rhythm management circuitry. The housing has an exterior defining a recess in which a header is received. The header has a number of lead bores, and includes an electrical contact within each bore, with each contact connected to the circuitry in the housing. The housing recess encompassing a major portion of the header, which may be positioned away from the corners of the housing, and which may be formed to avoid protruding from the housing. The recess may enclose at least three orthogonal sides of the header, and may include opposed parallel side capturing the header.

Cardiac performance associated with a current set of N pacing parameters is improved by adjusting the cardiac pacing parameters until optimal or substantially optimal cardiac performance is achieved. The cardiac performance associated with the current set of N pacing parameters is determined. An incrementing step, a determining step, and a increment updating step, are repeated for i=1 to N, where i represents which of the N pacing parameter is being adjusted. The incrementing step includes incrementing an ipacing parameter in the current set of N pacing parameters based on a corresponding iincrement value, to thereby produce an iset of test pacing parameters. The determining step includes determining a cardiac performance associated with the iset of test pacing parameters. The increment updating step includes updating the iincrement value based on the cardiac performance associated with the iset of test pacing parameters. Finally, after all of the N increment values have been updated, the current set of N pacing parameters is updated based on the updated increment values. The updated current set of N pacing parameters should provide superior cardiac performance than the previous current set of N pacing parameters.
