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.

Loading tool for a biostimulator

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.

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

Switching structures for hearing aid

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.

Switching structures for hearing assistance device

Systems, devices and methods are provided for selectively coupling hearing aids to electromagnetic fields. One aspect relates to a hearing aid device. In various embodiments, the hearing aid device includes an induction signal receiver for receiving induction signals, a microphone system for receiving acoustic signals, a hearing aid receiver, and a signal processing circuit. The signal processing circuit includes a proximity sensor for detecting an induction source. The signal processing circuit presents a first signal to the hearing aid receiver that is representative of the acoustic signals. When the induction source is detected, the signal processing circuit presents a second signal to the hearing aid receiver that is representative of the induction signals and transmits a third signal representative of the induction signals from the hearing aid device to a second hearing aid device. Other aspects are provided herein.

System and method for selectively coupling hearing aids to electromagnetic signals

A hearing aid is provided with a a programmable, signal processing circuit electrically connecting an input system to an output system, a magnetic field sensor, and a selection circuit connected to the magnetic sensor. The selection circuit may be adapted to control at least one of the input system, output system, and the signal processing circuit, where the selection circuit in conjunction with the magnetic field is configured to select the system or circuit to control based a magnetic field strength received at the magnetic field sensor being one of at least three levels of magnetic field strength.

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.

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.

Hearing aid with time-varying performance

A hearing aid having a battery door seal that substantially reduces or eliminates unwanted air flow from and into a battery compartment is provided. Eliminating unwanted air flow removes a potential source of acoustic feedback and provides significant improvement in frequency response of the hearing aid. The hearing aid includes a battery compartment with sidewalls that have a step joint formed between an opening in a faceplate to the battery compartment and a substantially flat portion of the sidewalls. The battery door has a lip that sets on the step joint when the battery door closes providing an air seal around a substantial portion of the battery compartment. A thin slit is provided between the faceplate and the battery door behind the end of the battery door, where the battery door is connected to the faceplate by a hinge to provide appropriate air flow for proper battery operation.
