In one embodiment of the present inventions, an exhaust outlet in a vacuum processing chamber includes a nonsealing flow restrictor which can facilitate rapid opening and closing of the flow restrictor in some applications. Because the flow restrictor is a nonsealing flow restrictor, the conductance of the flow restrictor in the closed position may not be zero. However, the flow restrictor can restrict the flow of an exhaust gas from the chamber to permit the retention of sufficient processing gas in the chamber to deposit a film on the substrate or otherwise react with the substrate. After a film has been deposited, typically in a thin atomic layer, the exhaust flow restrictor may be opened such that the flow restrictor conductance is significantly increased to a second, higher flow rate to facilitate exhausting residue gas from the chamber. The nonsealing flow restrictor may be closed again to deposit a second layer, typically of a different material onto the substrate. The nonsealing flow restrictor may be rapidly opened and closed to deposit alternating layers of a variety of materials onto the substrate.

The invention relates to leadless cardiac pacemakers (LBS), and elements and methods by which they affix to the heart. The invention relates particularly to a secondary fixation of leadless pacemakers which also include a primary fixation. Secondary fixation elements for LBS's may either actively engage an attachment site, or more passively engage structures within a heart chamber. Active secondary fixation elements include a tether extending from the LBS to an anchor at another site. Such sites may be either intracardial or extracardial, as on a vein through which the LBS was conveyed to the heart, the internal or external surface thereof. Passive secondary fixation elements entangle within intraventricular structure such as trabeculae carneae, thereby contributing to fixation of the LBS at the implant site.

The invention relates to leadless cardiac pacemakers (LBS), and elements and methods by which they affix to the heart. The invention relates particularly to a secondary fixation of leadless pacemakers which also include a primary fixation. Secondary fixation elements for LBS's may passively engage structures within the heart. Some passive secondary fixation elements entangle or engage within intraventricular structure such as trabeculae carneae. Other passive secondary fixation elements may engage or snag heart structures at sites upstream from the chamber where the LBS is primarily affixed. Still other embodiments of passive secondary fixation elements may include expandable structures.
