Abstract: A biostimulator transport system, such as a biostimulator delivery system, is described. The biostimulator transport system includes a flexible tether extending through a tether support to a tether bight. The tether bight loops through an attachment feature of a biostimulator to connect the biostimulator to the biostimulator transport system. Tether legs extend from the tether bight to a handle of the biostimulator transport system. The handle includes a housing and a knob, and the tether legs attach to the housing and the knob. A tether leg can be disconnected from the housing and the knob can be removed to pull the tether out of the attachment feature and release the biostimulator from the biostimulator transport system. Other embodiments are also described and claimed.

Abstract: A biostimulator delivery system having a tether cable, is described. A connector can be mounted on the tether cable to connect to a biostimulator. The connector can be a protuberance that lodges within the biostimulator, or a threaded connector that screws into the biostimulator. The tether cable has a stranded cable configuration, including several strands extending about a core strand in a helical direction. The stranded cable structure resists breaking under bending stresses typically seen during a tether mode used during delivery of the biostimulator. The tether cable reliably secures the biostimulator to the delivery system in the tether mode. Other embodiments are also described and claimed.

Abstract: A leadless biostimulator including an attachment feature to facilitate precise manipulation during delivery or retrieval is described. The attachment feature can be monolithically formed from a rigid material, and includes a base, a button, and a stem interconnecting the base to the button. The stem is a single post having a transverse profile extending around a central axis. The transverse profile can be annular and can surround the central axis. The leadless biostimulator includes a battery assembly having a cell can that includes an end boss. A tether recess in the end boss is axially aligned with a face port in the button to receive tethers of a delivery or retrieval system through an inner lumen of the stem. The attachment feature can be mounted on and welded to the cell can at a thickened transition region around the end boss. Other embodiments are also described and claimed.

Abstract: A loading tool for loading a biostimulator onto a biostimulator delivery system is described. The loading tool includes a first body portion and a second body portion connected by a hinge. A latch is mounted on the first body portion, and the latch can be locked to fasten the first body portion to the second body portion. A biostimulator can be mounted in the loading tool, and a tether of a biostimulator delivery system can be inserted through a funnel in the loading tool to engage the biostimulator. An operator can use only one hand to unlock the latch, open the loading tool, and remove the loading tool from the biostimulator prior to delivering the biostimulator into a patient. Other embodiments are also described and claimed.

Abstract: This application provides hearing aid devices including a housing, hearing aide electronics enclosed in the housing, and a capacitive switch coupled to the hearing aid electronics.

Abstract: A system includes a number of electronic devices that uses multiple voltage sources and a supply source to provide the different supply voltages without up-converting a voltage level or down-converting a voltage level. In an embodiment, the supply source is realized using a battery having multiple voltage taps, where the battery provides the multiple voltage sources. In an embodiment, the system is a hearing aid. A single battery includes a common substrate on which a number of battery regions is formed, where each battery region provides a supply voltage at a rated voltage level different than the other battery regions. The common substrate may be configured as a rigid platform, a flexible platform in a folded configuration, a flexible platform in a rolled configuration, or other platform configurations that provide for multiple battery regions on a single platform.

Abstract: A hearing aid is provided with a switch that automatically, non-manually, controls a configuration of the hearing aid in the presence of a magnetic field. In an embodiment, the switch in the hearing aid is configured to control a filtering configuration of the hearing aid in the presence of a magnetic field.

Abstract: A hearing aid is provided with a switch that automatically, non-manually controls at least one of inputs, filters, or programmable parameters in the presence of a magnetic field.

Abstract: A hearing aid that compensates for a patient's hearing deficit in a gradually progressing fashion. The hearing aid may be programmed to successively select in a defined sequence a parameter set that defines at least one operating characteristic of the signal processing circuit from a group of such parameter sets. The defined sequence may end in a parameter set that optimally compensates the patient's hearing.

Abstract: A simple cochlear implant is provided that can be implanted in a doctor's office under local anesthesia, which does not destroy residual hearing, and in a preferred embodiment, which is small enough to fit within a person's ear canal. The cochlear ear implant includes an exterior ear module, an interior ear module, and a cochlear electrode array. The exterior ear module includes a hollow housing within which are located the active electrical components including a microphone, power supply, and processor. The exterior ear module is easily removable from the body without surgery and is positioned in the auditory canal, the concha bowl or behind the pinna. The interior ear module is a semi-permanent assembly located immediately exterior to the tympanic membrane. It is a simple passive module for relaying signals to the electrode array. The communication of auditory signals from the exterior ear module to the interior ear module may be achieved by various techniques including by direct electrical transmission.
